Abstract: اجريت هذه الدراسة على عزلتين مختلفتين لبكتريا Salmonella ( typhi وtyphimurium ) تم الحصول عليهما من مختبر الصحة العامة في محافظة النجف خلال شهر كانون الاول 2014. تضمنت الدراسة ثلاثة محاور رئيسية , المحور الاول بكتريولوجي وتضمن دراسة تشخيصية للعزلتين وفق انظمة تشخيصية متقدمة ومعتمدة وتضمن المحور الثاني الكشف عن بعض عوامل الضراوة التي تمتلكها البكتريا كقدرتها على الحركة, وانتاج انزيم البروتييز والقدرة على تكوين biofilm اما المحور الثالث فقد تضمن دراسة مناعية تم من خلالها تحضير المستضد الجسمي والمصل التشخيصي متعدد التكافؤPolyvalent antisera لكل من العزلتين.تم اختبار البكتريا من خلال اجراء الفحوصات المجهرية والكيموحياتية وتقنيات Api - 20 والVitek2 ومن خلال نتائج تلك الفحوصات ومقارنتها بالصفات النوعية للبكتريا تاكد بانه العزلتين قيد الدراسة هما Salmonella typhi , وSalmonella typhimurium . اظهرت النتائج قدرة بكتريا Salmonella جنس typhimurium على استهلاك السترات , وانتاجها لكميات كبيرة لكبريتيد الهيدروجين على وسط kliglar iron agar في حين كانت لها القدرة على تخمير العديد من السكريات واهما سكر Arabinose . في حين كانت العزلة للجنس typhi غير قادرة على استهلاك السترات وانتاجها لكميات قليلة لكبريتيد الهيدروجين بالاضافة لعدم قدرتها على تخمير سكر Arabinose .كشفت الدراسة عن امتلاك بكتريا السالمونيلا لبعض عوامل الضراوة متمثلة بانتاج الانزيم المحلل للبروتينات protease enzyme وقدرتها على تكوين biofilm الذي تعتبر احدى العوامل الرئيسة في تلوث الاغذية المحفوظة وانتشار المرض اضافة الى قدرة البكتريا على الحركة بنشاط مما يمكنها من اختراق الطبقة المخاطية المبطنة للامعاء. ومن النتائج التي توصلت اليها الدراسة قدرة البكتريا على مقاومة المضادات الحيوية النيومايسن والكلورامفينكول الذي كان في السابق يعتبر المضاد الحيوي الاول في علاج الاصابة ببكتريا السالمونيلا في حين اظهرت البكتريا حساسية كبيرة للمضادين السيبروفلوكساسين والسيفترياكسون اضافة الى حساسيتها للمضادات كوتريميكسازول والتيتراسايكلين والنالدكسك اسد ,كما اظهرت العزلتين تباين في نسبة الحساسية الكبيرة الى المتوسطة للمضادين الاموكسلين والامبسيلين حيث كانت Salmonella typhi حساسة لتلك المضادات في حين كانت Salmonella typhimurium متوسطة الحساسية لتلك المضادات .المصل التشخيصي متعدد التكافؤPolyvalent diagnostic antisera تم تحضيره خلال طريقة مقترحة من قبل جامعه فلوريدا. حيث تم تحضير المستضدات الجسمية لكلتا العزلتين لبكتريا السالمونيلا المقتولة بالحرارة وحقن هذه المستضدات في الحيوانات المختبرية ( ارانب ) التي قسمت الى ثلاثة مجاميع حقنت الاولى والثانية منها بمستضدات جسمية مختلفة للعزلتين المختلفتين وباربعة جرع بين حقنة واخرى ثلاثة الى اربعة ايام في حين حقنت المجموعة الثالثة بالمحلول الملحي الفسلجي واستخدمت كمجموعة سيطرة للمقارنة تم بعد الحقنة الرابعة للحيوانات سحب الدم من الحيوانات بطريقة ثقب القلب تم عزل المصول واختبار كفاءتها في الكشف عن البكتريا من خلال فحص التلازن agglutination test لكلا المستضدين مع الاضداد المتمثلة بالمصل وكانت النتيجة موجبة لكلا الفحصين . اما عند مزج المستضد للعزلة الاولى مع الضد العزلة الثانية فقد اظهرت نتيجة موجبة للتلازن لكنها كانت ضعيفة مقارنة مع النتيجة الاولى, في حين عند عمل تفاعل مع بعض انواع من البكتيريا الواقعة ضمن العائلة المعوية فكانت النتيجة غير جديرة بالذكر | The present study was executed on two different isolates of Salmonella (typhi and typhimuruim) which were obtained from Central Health Laboratory in AL - Najaf province during December 2014. The study included three main parts. The first part was to confirm diagnosis of those isolates based on reliable diagnostic procedures. The second part concerned with the study of some virulence factors of Salmonella such as motility, production of protease enzyme and ability to formation of biofilm. The last part included immunological study including preparation of somatic antigen and polyvalent diagnostic antisera for each isolates. The suspected isolates were fully identified by using bacteriological, biochemical, API 20E and Vitek2 techniques. The results of these tests which compared with specific characteristics of Salmonella indicated, it was that the isolates included in this study were Salmonella typhi and Salmonella typhmurium . The results revealed that ability of Salmonella genus typhimurium was able to utilize citrate, produce high amount of H2S in Kliglar iron agar and ferment Arabinose sugar, while Salmonella typhi was incapable to citrate utilization and produce little amount of H2S in Kliglar iron agar and has inability to ferment Arabinose sugar. The results revealed that Salmonella produced virulence factors represented by producing protease enzyme and biofilm formation which consider as the main factor in contaminating of food and transmission of disease. The results exhibited a remarkable resistance of Salmonella to Neomycin and Chloramphenicol which was consider the first choice in treatment of Salmonella, but it was sensitive to Ciprofloxacin, Ceftriaxone, Cotrimoxazole, Tetracycline and Naldixic acid, while it exhibited variable sensitive to Ampicillin and Amoxicillin . Polyvalent diagnostic antisera were prepared according to protocol being suggested by Florida State University. Preparation of heat killed somatic antigen for each isolates of Salmonella, then were injected in three groups of laboratory animals (rabbits). The first and second group was injected with different somatic antigen in four successive doses with an interval time of three to four days, while the third group was injected with normal saline which used as control. Blood was collected from animals by intracardiac injection then serum has been separated and tested for its specificity by reaction with Salmonella typhi and Salmonella typhimurium using the agglutination test. The results were highly positive and specific, but when test antigen of first isolate with serum of second isolate will exhibit positive result with weak agglutination, then when cross reaction prepared antisera with live antigens of other some species belong Enterobactrecea the results was no considerable reaction

Abstract: This study was conducted to detect the invasive aspergillosis inimmunocompromised patients with rapid diagnostic method (ELISA).This study was conducted on 50 immunocompromised patients, theywere the attendants of Hematology / Oncology Department of BaghdadTeaching Hospital, pediatric oncology wards. The patients presented withfever which is not responding to antibiotics along with cough and sputumand abnormality on chest x - ray . And 11 healthy Iraqi individuals wereincluded in this study. from March 2013 till October 2013.Sputum and serum. initially direct microscopical examination donefor each sample and stained with gram stain. Sputum was immediatelycultured on Sabouraud dextrose agar (SAB) and Brain heart infusion agar(BHI) labeled with same code number of that sputum. Wet preparationwas down from colonies on Sabouraud dextrose agar plate or Brain heartinfution agar for isolation and identification of species of growingmould.This study showed that female to male ratio among patients studygroup was (1.2 : 1) .The age of the patients ranged from from 2 to 70 years with a meanage (31.8 ± 0.8) years. For the control the age ranged from 11 to 60 yearswith a mean age (31.1 ± 0.1) years. The peak mean age group (10 - 20)years with (5.1 ± 0.1).This study showed that 33( 66%) of patients were havingneutropenia which it is highly significant = 11.58 when the P value(P<0.01) , 10 ( 20% ) of patients were having neutrophilia and 7 (14%)of patients were having normal blood film results.IIThis study showed that sputum culture for Aspergillus positive in 18cases and it was negative in 17 patients, it was not done in 15 casesbecause some are from patients were sputum sampling was difficult to beobtained (pediatric), or have no sputum . And the Aspergillus speciesisolated from this culture showed that Aspergillus fumigatus is the most common species isolated from sputum culture 11 (61.1%) of positive culture results.The results showed high significant of AML diseases which composed 18 of 50 (36%) of patients , and most of the patients 24 of 50 (48%) of patients were on amphotericin B treatment.The results of the detection of galactomannan antigen detected by ELISA showed that the difference between the mean cutoff value of the patients and the control group was statistically significant (T = 0.135 and P value <0.05). In patient study group the ELISA test was positive in 39 of 50 (78% ) which it is highly significant when compared with noncancerous control group who were all negative 11 of 11 (100%) at p - value <0.001.Finally this study showed that (28 of 50) 56% of patients were dead because they are have invasive pulmonary aspergillosis (IPA) which is serious and potentially fatal disease that might kill the patients if any delay occurs in lab. diagnosis. So early diagnosis of invasive pulmonary aspergillosis may give higher cure rates.

Abstract: الداء الزلاقي هو مرض مزمن، يحدد مناعيا من شكل الاعتلال المعوي الذي يؤثر في الامعاء الدقيقة عند الاطفال والبالغين ذوالميول الوراثي . وتظهر بشكل سريع عند ابتلاع الاطعمة التي تحتوي على الغلوتين. ويشار ايضا الى انه ذرب الاضطرابات الهضمية والحساسية من الغلوتين في الامعاء او غير ذرب الاستوائية. يمكن تعريف الغلوتين بانه كتلة البروتين المطاط الذي يبقى عندما يتم غسل عجين القمح لازالة النشا. مكونات البروتين الرئيسية في الغلوتين (غليادين وغلوتينين) وهي بروتينات التخزين في الحنطة. استجابة الخلايا المناعية للغليادين تشمل زيادة التعبير من المستقبلات السطحية. بعض من هذه المستقبلات تشمل HLA - DR ، جزيء التصاق ما بين الخلايا ، CD3 ( في خلايا Tالناضجة ) ، CD25 وCD69 ( في خلايا T المنشطة والخلايا القاتلة الطبيعية ) .هدف هذه الدراسة هو التحقيق في القيمة السريرية لستخدام علامات CD في تشخيص الداء الزلاقي . اشتملت هذه الدراسة على 40 مريضا (21 من الذكور و19 من الاناث) مصابين بالداء الزلاقي حضروا مستشفى الجهاز الهضمي والكبد التعليمي في مدينة الطب ، وخلال الفترة ما بين فبراير 2013 الى حزيران 2013. كذلك تالفت مجموعة السيطرة من 40 شخصا اصحاء الذين لم يشكو من اي مشكلة في الجهاز الهضمي. وتم اخذ عينات من الدم الوريدي لكل شخص ( الدماء الجديدة لاجراء اختبار الكشف عن العلامات السطحية باستخدام تقنية التدفق الخلوي والامصال لاجراء اختبار tTG الاضداد الذاتية باستخدام تقنية الاليزا ) . هذه الدراسة بينت ان اعمار المرضى المصابين بالداء الزلاقي في هذه الدراسة قد تراوحت ما بين سنتين الى ستة وخمسين سنة وبمتوسط عمر (15.6 ± 13.1) سنة. انخفاض مستوى الدم من خلاياT اللمفاوية الموجبة لعلامة CD3 بشكل ملحوظ في الحالات ( المرض الزلاقي ) التي تراوحت بين (7.6 - 62.3) بمتوسط (36.8 ± 16.7) مقارنة مع مجموعة السيطرة التي تراوحت بين (4.4 - 62.1) بمتوسط (41.9 ± 16.9). في حين ان مستوى الدم من خلايا T اللمفاوية الموجبة لعلامة CD6بزيادة كبيرة في مجموعة الحالات التي تراوحت بين(1.8 - 25.6) بمتوسط (10.5 ± 5.1) بالمقارنة مع مجموعة السيطرة التي تراوحت بين(1 - 9.4) بمتوسط (3.6 ± 2.2) . كما اثبتت الدراسة الحالية ان هناك فروقات ذات دلالة احصائية في مستويات المصل الذي يحتوي اضداد ذاتية tTG - A (p < 0.001) والمصل الذي يحتوي اضداد ذاتية tTG - G (p < 0.007) بين الحالات والسيطرة. اخيرا استنتجنا ان علامة CD69 هي اداة دقيقة لتشخيص اولي للداء الزلاقي . كذلك هناك ارتباط كبيربين كل من المصل الذي يحتوي اضداد ذاتية tTG - A والمصل الذي يحتوي اضداد ذاتية tTG - G مع خلايا Tاللمفاوية الموجبة لعلامة CD69 في المرضى الذين يعانون من الداء الزلاقي | Coeliac disease is a chronic, immunologically determined form of enteropathy affecting the small intestine in genetically predisposed children and adults. It is precipitated by the ingestion of gluten - containing foods. It is also referred to as coeliac sprue, gluten - sensitive enteropathy, or non tropical sprue. Gluten can be defined as the rubbery protein mass that remains when wheat dough is washed to remove starch. The major protein components of gluten—gliadin and glutenin—are storage proteins in wheat. The response of immune cells to gliadins includes the increased expression of surface receptors. Some of these receptors include HLA - DR, intercellular adhesion molecule, CD3 (in mature T - cells), CD25 and CD69 (in activated T - cells and natural killer cells). This study conducted to investigate the clinical value of using CD markers in diagnosis of coeliac disease. A total of 40 patients (21 males & 19 females) with coeliac disease attending the Gastroenterology and Hepatology Teaching Hospital in the Baghdad Medical City, during the period between February 2013 - June 2013.The control group consisted of 40 apparently healthy individuals who were not complaining of any gastro - intestinal problem. Venous blood samples were taken from each subject (fresh blood tested for detection of surface markers by flow cytometry and sera tested for Anti - tissue transglutaminase auto - antibodies by Enzyme Link Immune Sorbent Assay).This study shows that the age of coeliac disease patients in this study was ranged between (2 - 56) years with the mean age of (15.6 ± 13.1) years. Blood level of CD3 positive T - lymphocytes was not significantly decreased in cases group that ranged between (7.6 - 62.3) with mean (36.8 ± 16.7) when compared with controls group that ranged between (4.4 - 62.1) with mean (41.9 ± 16.9), While the blood level of CD69 positive T - lymphocytes was significantly increased in cases group that ranged between (1.8 - 25.6) with mean (10.5 ± 5.1) when compared with controls group that ranged between (1 - 9.4) with mean (3.6 ± 2.2). Also the current study has been demonstrated that there were a statistical significant difference in the serum levels of tissue transglutaminase - A auto - antibodies (p < 0.001) and tissue transglutaminase - G auto - antibodies (p < 0.007) between cases and controls. Finally this study concluded that CD69 marker is an accurate tool for the diagnosis of coeliac disease. There were significant correlations between each of Serum tTG - A auto - antibodies and Serum tTG - G auto - antibodies with CD69 positive T - lymphocytes in coeliac disease patients.

Also, 30 patients with benign fibroadenoma as case control group their ages ranged between (19 - 52) years; with the mean age was 33.1+ 10.2 years. Those patients were diagnosed clinically, radiologically and cytologically and histopathologically by specialists, and they were among patients who attending the National Center For Early Detection Of Cancer - Medical City Complex / Ministry of Health, during the period from October 2011 to February 2012. Twenty apparently healthy subjects as a control group were included in the present study for comparison. Major findings of current study were the following : - 1. There was a statistical significant difference in the serum level of galectin - 4 between breast cancer patients and healthy control group (p > 0.001) and even between case control and healthy control groups (p>0.001), however , there was no statistical differences between patients and case control groups (p=0.92). Since no statistical significant differences in serum galectin - 4 median values between breast cancer patients (malignant tumors) and case control groups (benign tumors), therefore one can deal with breast tumor cases in general regarding serum galectin - 4.2. Also, The current study has been demonstrated that there was a statistical significant difference in the serum level of Toll like receptor - 2 between breast cancer patients and healthy control group (p > 0.001) and even between case control and healthy control groups (p >0.001), however, there was no statistical differences between patients and case control groups (p =0.44). Since no statistical significant differences in serum Toll like receptor - 2 median values between breast cancer patient (malignant tumors) and case control groups (benign tumors), therefore one can deal with breast tumor cases in general regarding serum Toll like receptor - 2 .3. The predictive value of the tested galectin - 4 to detect the validity of this parameter was studied since it had the highest accuracy (98.8) with sensitivity 100% within the cut off value (0.44ng/ml); therefore, testing positive at this cut - off value will establish a possible diagnosis of tumor with (95.2%) confidence in a clinical setting where the primary diagnosis of tumor had equal odds probability (50% pretest probability), and with (99.4% )confidence in a clinical setting where the primary diagnosis (based on history and examination) of tumor had a high probability (90% pretest probability).4. The predictive value of the tested Toll like receptor - 2 to detected the validity of this parameter was studied since it had the highest accuracy (97.5) with sensitivity 100% within the cut off value (0.14ng/ml); therefore, testing positive at this cut - off value will establish a possible diagnosis of tumor with (90.9%) confidence in a clinical setting where the primary diagnosis of tumor had equal odds probability (50% pretest probability), and with (98.9% )confidence in a clinical setting where the primary diagnosis (based on history and examination ) of tumor had a high probability (90% pretest probability).5. The median concentration of serum galectin - 4 was obviously higher (0.895 ng/ml) among those patients with average to long duration of disease (3months +) in comparison to those with very recent disease (> 3 months) and whose median concentration of galectin - 4 was (0.552 ng/ml). The difference observed failed to reach the level of statistical significance (p value= 0.12); however, there was a statistic significant weak positive linear correlation between disease duration and human galectin - 4 (r=0.268, p=0.039).6. The median concentration of serum Toll like receptor - 2 was obviously higher (0.619 ng/ml) among those patients with average to long duration of disease (1years +) in comparison to those with very recent disease ( > 3 months) and whose median concentration of Toll like receptor - 2 was (0.343 ng/ml). The difference observed failed to reach the level of statistical significance (p value= 0.049); however, there was a statistically non significant weak positive linear correlation between disease duration and serum Toll like receptor - 2 (r=0.16, p=0.22).7. Concerning tumor size categories, the median concentration of serum galectin - 4 was obviously higher (0. 895 ng/ ml) among those patients who were within the fourth (highest) quartile in comparison to those within the first (lowest) quartile (0 .567 ng /ml). There was a weak positive and statistically not significant linear correlation between tumor size and serum galectin - 4 concentration (r=0.046, p=0.76).8. Concerning tumor size categories, The median concentration of serum Toll like receptor - 2 was obviously higher (0.619 ng/ ml) among those patients who were within the fourth (highest) quartile in comparison to those within the first (lowest) quartile (0.288 ng /ml). There was a weak positive and statistically not significant linear correlation between tumor size and Toll like receptor - 2 concentration (r=0.145, p=0.34).9. For both (Galectin - 4 and Toll like receptor - 2) there were no statistical differences in serum median concentration between ductal carcinoma in situ and infiltrative carcinoma (p =0.12, 0.64 respectively)

Abstract: Parvovirus B19 is a small single - stranded DNA virus and the only member of the species Parvoviridaeknown to infect humans. The virus exhibits a strong tropism for erythroid progenitor cells using the erythrocyte globoside P antigen as a surface viral receptor. In the setting of shortened red blood cell survival, mild pancytopenia characterized by transient and spontaneous recovery in healthy subjects. Nevertheless; severe aplastic anemia associated with parvovirus B19 infection may precede or be associated with acutelymphoblastic leukemia (ALL) that has been described in a number of reports.The attenuated immune response in these patients may obscure the serologic and clinical manifestations of infection. Infection may mimic a leukemic relapse or therapy - induced cytopenia, and may lead to hospital admission, frequent blood sampling, renewed bone marrow aspirates, multiple transfusions of red blood cells (RBCs) or platelets, and cessation of maintenance chemotherapy for up to 3 weeks in children with ALL.Materials & Methods : A cross sectional study involved forty five patients with ALL were currently attending department of oncology in Children'sWelfare Teaching Hospital in medical city of Baghdad between December 2012 and April 2013.Twenty one patient who newly diagnosed with ALL and 24 who underwent chemotherapy.Their age ranged from 8 months to 15 years with mean age ±SD equal to6.54±4.2 years. Compared to forty five of apparently healthy children who were already under pre operative screening tests. They included in this study as a control group, age and sex were matched.The practical part of this study performs the followings : 1 - Serological detection of parvovirus B19 specific antibodies (IgM and IgG) in patients’ serum using enzyme linked immunosorbant assay (ELISA).2 - Molecular detection of parvovirus B19 - DNA using Real - time PCR for viral load measurement.3 - Other tests : include hematological tests which were done routinely for patient assessment.ResultsB19 - IgM was detected in 7 out of 45 patients tested (15.6%) compared to 2 out of 45 (4.4%) apparently healthy children whom belong to control group. No Statistical significant difference was observed (P - value >0.05) and the risk of parvovirusB19 infection in children with ALL was 3.96 times (odds ratio).B19 - IgG was detected in 18 out of 45 patients (40%) compared to 6 out of 45 (13.3%) of apparently healthy children. Statistical significant difference was clearly noticed (P - value < 0.05).Four out of 21(19.05%) children whom newly diagnosed with ALL had acute parvovirus B19 infection compared to 3 out of 24 (12.5%) children on maintenance chemotherapy gave positive parvovirusB19 - IgM.Parvovirus B19 IgG antibodies were detected in 8 out of 21(38.1%) 0f newly diagnosed children with ALL compared to 10 out of 24 (41.7%) children on maintenance chemotherapy.The correlation between parvovirus B19 IgG - and IgM - Antibodies among study groups shows that 4 out of 45 (8.9%) was detected to be positive in children with ALL group compared to control group which revealed no detectable combined B19 IgG/IgM antibodies.Parvovirus B19 - DNA was detected in 6 out of 45(13.3%) compared to none detectable DNA signals among the control group. All cases with positive parvovirus B19 nucleic acid signals were underwent maintenance chemotherapy which were represented in 6 out of 24(25%), statistical significant difference were noticed among study cases. The viral load was ranged from (65x103 - 106 copies/ml) with mean of (36x104 copies/ml).In newly diagnosed ALL cases, only one case (4.7%) had IgM/IgG antibodies and 3 out of 21 cases (14.3%) gave IgM positive antibodies. While children on maintenance chemotherapy ,a combined IgM/IgG were detected in 3 cases out of 24(12.5%), 3 cases with both IgG and B19 DNA signal detection and only two (8.3%) children on maintenance chemotherapy gave positive B19 DNA signal (P - value < 0.05).The effect of B19 infection on blood parameters during recent, prior and absent infection for studied groups showed that the mean values of hemoglobin were 8.5±1.8, 6.5±2.5 and 8.5±2(g/dl) in children with ALL who were proved to have positive IgG, IgM and B19 DNA respectively compared to12.8±0.7 among control group (P<0.05). Other blood parameters showed a decreased RBC count which were estimated in cases with positive anti B19 IgG was 3±0.7 anti B19 IgM was 2.5±0.9whereas, mean RBC count was2.9±0.6 in association with B19 cases DNA detected signals (P<0.05). Furthermore, acute B19 - infection associated with a decreased WBC count among ALL cases with (p<0.05), a remarkable decrease in platelets count was appeared in cases with acute B19 infection (P<0.05).Regarding clinical symptoms and signs associated with B19 infection, 2 out of 7 (28.6%) cases with peticheal rash had acute infection with B19 virus, 3 out of 7 (42.9%) ALL cases with acute B19 infection complained from Arthralgia and 8 out of 18(44.4%) cases had non - specific fever and proved to have acute B19 infection, one ALL case with positive B19 IgM and/or B19 DNA out of 3 (33.3%) with bilateral cervical lymphadenopathy, 5 out of 6 (83.3%) cases with acute B19 infection had hepatosplenomegaly.Based on the sample studied, 15% of true B19 - IgM was identified by ELISA test compared to13% of true B19 - DNA signal detection by real time - PCR, whereas 100% of correctly no detectable B19 - DNA signal was identified in healthy control using real time - PCR, compared to 95% of negative B19 - IgM in serum level among control group using ELISA.A child who has a detected B19 - DNA signal by real time - PCR has a 100% chance of having acute infection compared to 77% chance of using ELISA test.Conclusions The study results are consistent with previous studies which appear that children who suffering from ALL are at increased risk of B19 infection. The use of real time PCR detects high B19 - DNA viral load. Notable percentage ofpersistent B19 infection was recorded among children with ALL who are receiving ongoing treatment, in addition, most of acute B19 infected ALL cases were asymptomatic. Acute B19 - infection was shown to be an important cause of anemia and cytopenia in children with ALL.Recommendation : Further follow up studies are necessary to clarify the role

Abstract: A total 100 samples, only nineteen isolates of S. aureus were obtained from different samples includes (urine ,vagina, stool, wound, and abscess ) from patients by standard bacteriological methods. All samples were obtained from patients or individuals who admitted to Al - Hillah Surgical Teaching Hospital and Merjan Medical City in Babylon Governorate during a period extending from (July 2017 to September 2017). Then the specimens cultured in selective media and identified by using biochemical and bacteriological tests and using specific primer(sau).Only (19)isolate of Staphylococcus aureus isolates were recovered.Some virulence factors of all S. aureus isolates were studied as sea gene , PCR was performed using specific primer on genomic DNA from S .aureus isolate . PCR amplification of sea gene indicated that two from vagina isolate 2 : 4(50%),three from urine 3 : 3(100%) and four from stool 4 : 4(100%) and one isolates from abscess 1 : 4(25%) and one isolates from wound1 : 4(25%) .Specific PCR primer was used for the detection of( tsst) gene.It was found that tsst gene was observed in 16 isolates which include urine, pus ,wound,and stool in percentage 100%.Specific primer was used for detection of eta gene .It was found that eta was observed in three from urine 3 : 3(100%), four from vagina 4 : 4(100%) and three from abscess 3 : 4(75%) and four from wound4 : 4(100%) and four from stool 4 : 4(100%).cna gene was also detected in S.aureus by using specific PCR primer .It was found that can gene was observed in two from urine 2 : 3(66.6), one from vaginaII1 : 4(25%), three from wound 3 : 4(75%) and three from abscess 3 : 4(75%) and two from stool 2 : 4(50%) .Also, ica gene was detected in S.aureus isolates by using specific primer , it was found that gene present in 2(66.6%) isolate from urine sample and 1(25%) isolate from abscess sample.However, molecular detection of pvl gene was done using specific PCR primer. It was found that pvl was observed in bacterial isolates in only 2(50%) isolate from abscess sample and 1(25%) from wound sample.Clumping factor A (clfA) gene was investigated by PCR technique using specific primer for his gene. It was found that clfA gene was observed in three from urine sample 3(100%) and one from vagina 1(25%) and four from abscess 4(100%) and four from wound 4(100%) and three from stool 3(75%).S. aureus isolates were subjected to show its ability to produce staphylokinase enzyme .It was that only 2 from 4 (50%) isolates from wound extracylallary were able to produce staphylokinase enzyme by creating clear zones around wells containing their cultures in the skim milk agar plate.Hyaluronidase activity was also investigated it was found that( 89%) of S. aureus isolates give positive result for hyaluronidase by turbidity reduction assay in the determination of hyaluronidase.The relationship between 19 S. aureus isolates using RAPD - PCR was performed. Ten primer showed polymorphism among the isolates test generatingIII88 bands, 58 of which were polymorphic with sizes ranging between 100 to 3000 bp. The mean percentage of ten primer 61.36% .The Dendogram two main cluster, the first include one isolate (st9 abscess) and the second include 18 isolates, However , the second cluster divide the 18 isolate into two subcluster. Using the ten primer isolate 11 reveled highest similarity with isolate 1 (69%) and the isolate 17 and 18 have similarity (69%) followed by isolates 7 and 16 with similarty (61%) .However , isolate 14 and 9 showed the lowest similarity (10%). All the remaining pairs showed intermediate similarity percentage with highest and lowest percentage .PCR amplification of Agr group gene from 19 isolates product different types based on size range from (323 - 659 ) bp were recognized as follows Agr I (441bP) ,Agr II(575 bp),Agr III(323 bP),Agr IV (659 bp),and. The frequencies of agr Groups III 17(89.1%) and Agr Groups I 15(78.7%) were more than those seen in other Groups flowed by agr IV 7(36.7%), while agr Group II 2(10.4%) was the least obtained in all the five isolates .DNA sequencing of cna gene from isolates of S. aureus revealed 188 mutation in four isolates and give identity in percentage (76 - 89%) with standard strand S. aureus in NCBI website ,this gene sequencing is the first described in Iraq.

Abstract: تعتبر Escherichia coli وEntamoeba histolytica من اكثر مسببات الامراض الشائعة التي تسبب الامراض المعوية والامعائية في جميع انحاء العالم.تم جمع 150 عينة براز من المرضى الذين يعانون من الاسهال الكبير خلال الفترة من اكتوبر 2017 حتى نهاية ديسمبر 2017 من ثلاثة مستشفيات رئيسية في مدينة الحلة ، وقد تم تشخيص 46 عزلة على انها E.coli والكشف عن 28 عينة على انها E.histolytica.شملت عزلة ال E.coli ما ياتي 29 من الذكور و17 من الاناث ، في حين شملت E.histolytica 19 من الذكور و9 من الاناث.تتراوح الفئة العمرية الاكثر شيوعا لانتشار العدوى في كل من E.histolytica وE.coli (1 - 10) سنوات . وهذا يمكن ان يكون وفقا لحقيقة ان الاطفال يلعبون على التربة مع نظافة ضئيلة او معدومة ضمن هذه الفئة العمرية او بسبب انخفاض المناعة خلال هذه الفئات العمرية.ظهر من عزلات E.coli ان اكثر انواع الاسهال شيوعا هو 14 اسهالا مائيا في حين كان في عينات E.histolytica الاسهال الدموي هو الاكثر شيوعا حيث بلغ 18 اسهالا دمويا.كان عامل الاقامة الاكثر شيوعا في كل من E.coli وE.histolytica في المناطق الريفية حيث كان حوالي 32 في E.coli و18 في E.histolytica. ويرجع ذلك الى العديد من العوامل مثل وجود الحيوانات الاليفة كمضيفين والتي تساعد على توزيع الاصابات المايكروبية ، غياب معظم المبادئ الصحية العامة ، غياب اجراءات الصرف الصحي ، تقديم الطعام والماء الملوثين .وقد درست بعض عوامل الضراوة في بكتريا القولون التي اختبرت في الدراسة الحالية لانتاج كبسولات كانت النتائج الايجابية 37 ، وكان مستضد عامل الاستعمار 18 ، وكان انتاج الهيموليزين صفرا ، وكان انتاج البكتريوسين 46.ان اكثر الانماط المصلية المنتشرة لبكتريا E.coli هو ETEC وقد كان 16 عزلة. تم اختبار تاثير بعض المضادات الحيوية على E.coli واظهرت النتائج التي تم الحصول عليها ان اعلى ارتفاع معدل مقاومة كان 43 الى ampicillin و42 الى Ceftriaxone في حين ان اعلى ارتفاع معدل انتشار الحساسية كان 43 الى Meropenem و34 الى amoxiclave.تم اختبار انتاج ESBL بواسطة E.coli في هذه الدراسة عن طريق الفحص والاختبار التاكيدي الذي كان 10 عزلات لديهم القدرة على انتاج ESBL باستخدام اختبار الفحص العادي في حين ظهرت 20 عزلة بواسطة الاختبار تاكيدي.كما تم الكشف التاكيدي ل E.histolytica بواسطة ELISA في 28 عينة التي تم الحصول عليها وجميعها اعطت نتائج موجبة | Escherichia coli and Entamoeba histolytica are among the most common pathogens that causes intestinal and extra - intestinal diseases worldwide .One hundred fifty (150) stool samples were collected from patients suffering from significant diarrhea during the period of October 2017 to the end of December 2017 from three main hospitals in Hilla city, about 46 isolates were identified as Escherichia coli and 28 Entamoeba histolytica were detected in all specimens. From 46 isolates of E.coli were included 29(63.1%) in males and 17(36.9%) in females , while from 28 E.histolytica about 19(67.9%) in males and 9(32.1) in females .The most prevalence of infection by both E.histolytica and E.coli were among age group range (1 - 10) . This could be according to the fact that children are found of playing on the soil with little or no hygiene within this age group or due to low immunity.The most common type of diarrhea in this study were 41(89.2%) watery diarrhea caused by E.coli while the 18(46.2%) bloody diarrhea were the most common in diarrhea cases by E.histolytica.Most cases of diarrhea were commonly in both E.coli and E.histolytica cases in rural that about 32(69.6%) by E.coli and 18(64.2%) by E.histolytica .These are due to many factors such as the presence of domestic animals as hosts which help in parasites distribution ,an absence of most common hygienic principles ,absent of sanitation measures , present of contaminated food and water, and the presence of insects as vectors to these pathogens .Some virulence factors of E.coli which have been tested in the present study were involve capsule production that positive results about 37(80.5%) ,colonization factor antigen were 18(39.1%), hemolysin not produced , and bacteriocin production were about 46(100%) . The high prevalence of E.coli serotypes in this study are with Enterotoxigenic E.Coli that about 16(34.8%) isolates. The enterotoxigenic E.coli pathotype is recognized as one of the main important diarrheagenic E.coli in developing countries.The effect of some antibiotics on E.coli was tested and the results that obtained show that the high prevalence of resistance 43(93.4%) to ampicillin and 42(91.4%) to Ceftriaxone while the high prevalence of sensitivity were 43(93.4%) to meropenem and 34(73.9%) to amoxiclave . The Extended Spectrum β - Lactamase production by E.coli in this study also tested by confirmatory test that was about 20 isolates were having the ability to produce ESBL by using confirmatory test.The confirmatory detection of E.histolytica by using ELISA were also applied in this study were the results give 28(100%) positive for E.histolytica .

Abstract: A total of 200 samples were collected from different sources of patients that including (sputum , tonsil, sinuses, vagina, urine) and from both sexes during a period from September 2016 to December 2016. Only twenty isolates (10%) were identified as Klebsiella pneumoniae positive according to the cultural characteristics and biochemical tests. Eight (40%) isolates from sputum, 5(25%) isolates from urine, 3(15%) isolates from tonsil, 2(10%) isolates from sinus, and also 2(10%) isolates from vagina. K. pneumoniae in males formed 12 isolates(60%) and 8 isolates(40%) in the females .The age - groups of patients who involved in the study was ranged from one year to thirty years old. The results showed that the mean age of patients was 14.9 years with standard deviation of 10.96. All isolates (100%) were able to produce capsule, siderophore, colonization factor antigen(CFA I/CFAIII) and urease, but none of these isolates were able to produce hemolysin. They have ability to form biofilm and have a strong role in stone formation. Regarding antibiotic susceptibility testing all Klebsiella pneumoniae isolates were resistant to Aztreonam, Ampicillin, Amoxicillin/ clavulanic acid) and penicillin G, whereas sensitive to Gentamycin, Ceftriaxone, and Amikacin. The molecular detection of some virulence genes ( magA gene, kfu gene, and uge gene) was done by PCR technique. And all isolates (100%)were negative mag A. Also, PCR technique displayed that 5 isolates 20(25%) were positive for Kfu gene, while only two isolates 20(10%) were positive for Uge gene. As well, the antibiotic resistance genes bla TEM and bla SHV markers were investigated, 18(90%) isolates positive to bla TEM from them(14) isolates carried on plasmid and (4) isolates carried on chromosomal DNA, while bla SHV gene was found in 17(85%) isolates positive from them (14) isolates carries on plasmid and (3) isolates carried onchromosomal DNA. Moreover, RFLP/PCR analysis explored bla TEM and bla SHV genotyping for Klebsiella pneumoniae isolates in the current study illustrating ESBL contribution in the increment of bacterial resistant to antibiotics.

Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp. among pediatric patients in Babylon province, Iraq. Out of 191 different clinical samples were collected from pediatric patients during the a period of July 2016 till November 2016. Samples were obtained from aged from 1day till the age of pediatric patients 14 years old who admitted to Babylon teaching hospital for maternity and children (mainly in nursery neonatal care unit, intensive care unit, general wards) and Hilla teaching hospital (mainly in burn unit). Samples obtained included; blood, urine, cerebrospinal fluid, burns wounds and others (bronchial fluid, abscess) data like name, age, sex, residence, body weight, attending for vaccination program before or after, any clinical documented infection or not, and whether received antibiotics before or after, were taken from patients before sampling.Among 191 clinical samples, 45 (23.5%) gave positive growth on ordinary culture media, yielding 45 bacterial isolates, identified using biochemical tests,Vitek2 - system ID cards, and API system. The bacterial isolates were recovered form urine 16 (35.5%), burn wounds 15 (33.3%), blood 13(28. 8%), and bronchial fluid 1 (2.2%). Among 191 clinical samples, 146 (76.4%) gave no growth. The reason of negative culture may be attributed to fungal infection, viral infection, fastidious bacteria that might be lost during transporting or antibiotics usage before taking samples. Out of the total samples collection 191, ESKAPE pathogens group corresponded 12 isolates (6.3%) were recovered. While (26.6) from positive growth cultures. They were isolated from samples of burn wounds 6 (50%), blood 5(41.6%), and bronchial fluid 1(8.3%). Among 12 isolates of (6.3%) ESKAPE pathogens group from 191 recovered from clinical samples, S. aureus was recovered in high rate (33.4%) followed by P. aeruginosa, K. pneumoniae, and A. baumannii However, no isolate belonged to E. faecium was recovered in this study. Results of antibiotic susceptibility testing of ESKAPE pathogens group using Vitek 2 - system found that P. aeruginosa isolates showed high rate of antibiotic resistance, followed by K. pneumoniae, S. aureus, E. cloacae, and A. baumannii isolates respectively. Different antibiotic susceptibility patterns were recorded among ESKAPE pathoges group isolates. Multi drug resistance (MDR) was found in high rate 10 (83.3%), and extensively drug resistant (XDR) 2(16.6%) , However, no isolates belonged to pan drug resistant (PDR) were recovered in this study. In the present study found that high rate 6/8 (75%) from the all isolates of G - ve bacteria within ESKAPE pathogens group (P. aeruginosa, K. pneumoniae E. cloacae, A.baumannii) were ESBL - producers and all isolates were AmpC producer.According to we knowledge, this study is a first record of investigation the prevalence of pattern resistant bacteria among ESKAPE pathogen group in pediatric patients in Iraq

Abstract: هدفت هذه الدراسة الى توضيح العلاقة بين البالغين الذين يعانون من السمنة والتعرض للعدوى الميكروبية من خلال تقدير المعايير المناعية مثل (IFN - γ & IL - 2)، عناصرcomplement system (C3, C4) , وقياس فعالية الخلايا المناعية الالتهامية من خلال الكشف عن الاصابة بـ Streptococcus pyogenes وMeasles virus. انجز هذا العمل على 50 شخصا من ذوي السمنة البالغين (11 ذكرا و39 انثى) تتراوح اعمارهم من (20 - 60) عاما قاموا بزيارة قسم التغذية في مستشفى مرجان التعليمي في محافظة بابل خلال الفترة من نوفمبر 2014 الى يناير 2015، و30 شخصا اخرين اصحاء لا يعانون من السمنة (21 ذكور و9 اناث) تتراوح اعمارهم من (22 - 42( عاما. وتم قياس مؤشر كتلة الجسم (BMI) لكل فرد من ذوي السمنة والاصحاء. تم جمع عينات الدم من كلا المجموعتين لقياس فعالية الخلايا الالتهامية، والمعايير المناعية الاخرى مثل (IFN - γ & IL - 2)، وعناصر complement system (C3, C4), والكشف عن الاصابة بـ Streptococcus pyogenes وMeasles virus بطريقة الامتزاز المناعي المرتبط بالانزيم. اظهرت النتائج ان تركيز (IL - 2) عند ذوي السمنة اقل بكثير وبشكل معنوي عن الذين لا يعانون من السمنة (P˂0.05) ، ولم يظهر تركيز IFN - γ)) في مجموعة ذوي السمنة انخفاضا معنويا (p>0.05) عن تركيزه عند الاصحاء. وكانت عناصر complement system (C3, C4)مرتفعة عند ذوي السمنة وبشكل عالي المعنوية (p˂0.001) عن مجموعة الاصحاء الذين لا يعانون من السمنة، ولكن فعالية الخلايا الالتهامية اظهرت انخفاضا عالي المعنوية (p˂0.001) عند مجموعة ذوي السمنة (6.1٪) مقارنة بمجموعة الاصحاء (10.6٪)، وزيادة تراكيز كل من ASO وanti - measles virus - IgG وبشكل عالي المعنوية (p˂0.001) عند ذوي السمنة مقارنة بالاصحاء | This study aimed to clarify the relationship between obese adults & susceptibility to microbial infections by evaluating the parameters of cytokines (IFN - γ & IL - 2), complement components (C3 & C4), and phagocytic index using of Anti - Streptococcus pyogenes Ab and Anti - Measles virus - IgG Ab as indicators of infections. This work was applied on 50 obese adults visited to the center of nutrition in Marjan hospital in Babylon province from November 2014 to January 2015, and 30 non - obese apparently healthy as controls. Obese adults consist of (11 males and 39 females) with age range 20 - 60 years, while 30 apparently health controls consist of (21 males and 9 females) with age range 22 - 50 years. Body mass index (BMI) for all subjects obese & controls was estimated. Blood samples were collected from obese group and control group to estimate phagocytic index, and ELISA test for cytokines (IFN - γ & IL - 2), complement components (C3 & C4), and detection of measles - IgG antibody and anti - streptolysin O antibody. IL - 2 concentration in obese adults was significantly lower than non - obese adults (p˂ 0.05), and no significant decreased (p>0.05) of IFN - γ in obese group, the complement components (C3 &C4) in obese adults were a highly significant than controls, but the phagocytic index showing there is a highly significant decreased (p˂0.001) in activity of neutrophils of obese adults (6.1%) compared to control group (10.6%), ASO and Anti - measles - IgG concentrations increased in obese adults with a highly significant (p˂0.001) as compared to controls. This findings can be concluded as that obese subjects have low levels of immune system and more susceptible to be infected with microbial infections

Proteus spp وEnterobacter ايجابية لتفاعل الجيلاتيناز، في حين ان جميع العزلات من Klebseilla واكثر عزلات E.coli سالبة لهذا العامل. واظهرت نتائج اختبار انتاج ال lipase في سالبة الجرام ان معظم العزلات ايجابية لاختبار lipase. وكشفت النتائج ان جميع العزلات كانت موجبه Biofilm وضع تشكيل (50٪)، في حين لا يوجد عزلات سالبه له. وفيما يتعلق بعوامل الضراوة الشائعة للبكتيريا المعزولة من عدم وجود مرض السكري وعوامل الضراوة فكانت نادرة. وكانت نتائج المتغيرات المناعية (C3، C4، Ig A، IL4، وIL6) للمرضى السكري في الدراسة, قد انخفضت مستويات C3، IgA، IL4، وIL6 للمرضى السكري ، في حين مستوى C4 قد ارتفع. من خلال نتائج هذه الدراسة، يمكن ان نستنتج؛ ان انواع البكتيريا التي عزلت من مرض السكري من النوع الثاني هي التالية E.coli تليها K. Pneumoniae, Enterobacter spp., Proteus spp, Micrococcus, Citrobacter S.epidermidis, kocuria kristinae, S.aureus , and Streptococcus spp. والطفيليات هي الاميبا الحاله للنسيج ثم الجيارديا اللامبيليا | In this study include (100) diabetic type (II) patients as diagnosed by Diabetolegist and 50 healthy control with an age range of (25 - 65 years) who attended to the two hospitals in Babylon : (Al - Qasem and Marjan), during the period from January 2015 until June 2015. Shown that grams - negative bacteria constitutes 74% from the total isolates and were considered the predominant aetiological agent of DM compared to gram - positive bacteria which constitutes 26%. The most common bacterial isolates were E.coli followed by Klebsella Pneumoniae, Enterobacter spp, Proteus spp, and less common bacteria were Staphylococcus aureus, Staphylococcus epidermidis, Kocuria kristinae, Citrobacter, Micrococcus and Streptococcus spp, whereas the most common parasites were Entamoeba histolytica 55% and Giardia lamblia 45%.The virulence factors of common bacterial isolated from diabetes Mellitus type II in this study are studied. The capsule was present in all Klebsella pneumoniae isolates, Enterobacter isolates and some isolates of E.coli, whereas the other bacteria such as Proteus mirabilis isolates in this study does not possess the capsule. Colonization factor antigens were detected; The CF - I and III were detected in mostly bacterial isolates which showed positive results with these factors. All isolates of Staphylococcus aureus bacteria were able to produce coagulase which is considered as a virulence factor for pathogenicity of these bacteria. All isolates of Staphylococcus aureus and E. coli expressed β - hemolytic (complete lyses), while all isolates of Streptococcus were α - hemolytic pattern (incomplete lyses) showing a greenish line around the bacterial colonies. All isolates of Staphylococcus epidermidis and some isolates of Proteus spp. were γ - hemolytic (non hemolytic). In the present study the siderophore synthesis was investigated among bacterial isolates and the results showed that all bacterial isolates (E. coli and K. pneumonia), and mostly of isolates of Enterobacter spp. and Proteus spp. were able to synthesis siderophore. Some isolates of Proteus mirabilis and Enterobacter spp. were positive for gelatinase reaction, while all isolates of Klebseilla pneumoniae and mostely E.coli were negative for this factor. The results of lipase production test in G - ve showed that most isolates were positive to lipase production test. The results revealed that all isolates were biofilm former, high and moderate biofilm formation mode were account for (50%) while there is no isolates that express non - biofilm formation. Regarding the virulence factors of common bacterial isolated of non - diabetes Mellitus have rare virulence factors.The results of Immunological parameters (C3, C4, IgA, IL4, and IL6) for DM patients were studied. In this study the levels of C3, IgA, IL4, and IL6 for DM patients were decreased, whereas the level of C4 was increased. In light of the results documented in this study, we can conclude the following; the types of bacteria which isolated from diabetes mellitus type II from the most to least common are E.coli followed by K. Pneumoniae, Enterobacter spp., Proteus spp., S.aureus, S.epidermidis, kocuria kristinae, Citrobacter, Micrococcus, and Streptococcus spp. And parasite : Entamoeba histolytica and Giardia lamblia isolated from diabetes mellitus type II. Most bacterial isolates in this study have the ability to possess more than one virulence factor such as capsule, siderophors, lipase production, hemolysin, extracellular protease, adherence factors, and biofilms to produce infection in diabetes mellitus type II patients. The virulence factors of common bacterial isolated in non - diabetes mellitus have rare virulence factor. The levels of Immunological parameters of C3, IgA, IL4, and IL6 for DM patients were decreased, whereas the level of C4 was increased.

The study show that the highest percentage of isolated fungi was from males as it was(51.4)% while in females was (48.6)%. Patients' ages were found to be between (11 - 80) years and the age group (21 - 30) years was the most frequent Category in (30.3)% and the Category (71 - 80) years was affected only in (0.8)%. The highest percentage of insulation fungi during the period of sample collection was in February which constitute (30.9)% and the lowest percentage was in March reaching only (14.1)%.The highest ratios to isolate the fungus was recorded among housewives and unemployed males and it was (44.2%), while the lowest rates of insulation when the students reached (15.9%).The cases of otitis media excelled on the rest of the pathological cases accompaniments of Otomycosis as the proportion of insulation was (19.4%), followed by disease of blood pressure which their percentage was (5.3%), while the rest of the pathological cases did not have significant influence in insulation, for more ear side affected the left ear was affected in(51.8)% and the right was affected in (48.2) %. The study showed that there is inhibitory effect of (flucanazole, Nystatin, Clotrimazole, Miconazole, Itraconazole and Ketoconozole) against Aspergillus spp (A.niger, A.flavus and A.terreus). All antifungals were effective and their inhibitory ratio was (100) %, except for the antifungal (Fluconazole ) which found to have a lower inhibitory effect (10) % against the species A.flavus only. Testing the phospholipase activity for aspergillus species, A.flavus and A.niger showed phospholipase activity in two degrees (++, +++), but A.terreus shoed only (++). Searching the gene alp " which is encoded for the production of alkaline protease " showed that all the Aspegillus species produces the gene with amplification results of (100)% for the band supposed to appear at the molecular weight of (747) pb

Abstract: Between September and November 2013 a total of 140 urine specimens obtained from patients in Al - Kadhmiah Teaching Hospital, Ibn - Al Naffees Teaching Hospital, and Educational Laboratories in Medical city. These midstream urine specimens were obtained from patients clinically suspected to have urinary tract infection (UTI) in sterilized containers. All specimens were processed immediately after collection.A total number of 140 specimens of mid - stream urine were collected from patients suffering urinary tract infection symptoms. These isolates were obtained from 41 male and 99 female patients. They were distributed in the age group of 5 - 60 years old. All specimens were identified using biochemical tests and API 20 E system. 60 (42.85%) of urine specimens was Escherichia coli and 15(10.71%) of specimens growth was Klebsiella spp. and 25(17.85%) growth was Proteus spp. and 40 (28.57%) was G+ve bacteria.The adherence ability of E.coli isolates were evaluated by using Congo red agar and detected their ability to produce biofilm by using methylene blue staining technique in polystyrene microtiter plates and then Optical density was determined at 580 nm.All sixty isolates of E.coli were grown on Congo red agar medium to detect their adherence ability. Twenty (33.3%) isolates were given negative result by forming pink colonies on congo red agar, were as, forty (66.6%) isolates were given positive result by forming black colonies with a dry crystalline. Three isolates give strong results E.coli (13, 8, and 40). Consistency indicated biofilm production by microtiter plate. E. coli 40 which isolated produced the thickest biofilm (O.D. : =3.17).Type 1 fimbriae expression by E.coli 40 isolate was detected by mannose - resistant hemagglutination (MRHA) of human blood group (O) IRBCs in the presence of 2% D - mannose. The isolate showed strong MRHA characteristics of type 1 fimbriae under microscope (40x). The E.coli E.40isolate which produced the thickest biofilm and gave strong MRHA was elected to be the source of type 1 fimbriae.Type 1 fimbriae was extracted by heating and mechanical shearing and partially purified by Ultracentrifugation (48, 000xg for 3hrs). SDS - PAGE with a molecular weight 20, 000 Dalton.Anti - type1 fimbriae antisera were prepared in rabbits. The specificity and titration of anti - type1fimbriae antibodies were determined using IgG protein by radial immunodiffusion plate and bacterial agglutination. IgG antibodies to fimbriae type 1 were also detected in rabbit sera from immunized rabbit and non - immunized. Immunized rabbit test 1 had increases in Fim1 - specific IgG antibodies (9.5) mg/dl. Immunized rabbit test 2 had increases in Fim1 - specific IgG antibodies (8.6) mg/dl. The non - immunized rabbit had no increase in absolute IgG antibodies to Fim1.The antisera agglutinated bacterial cells up to 1/80 dilution confirming the presence and titer of specific antibodies against type1 fimbriae.The microtiter plate method was applied to estimate the role of the prepared anti - type1fimbriae antibodies in reducing the biofilim formation by E.coli. Prevention of bacterial adherence and subsequent biofilm formation to polystyrene microtiter plate was studied by employing different dilutions (1/10, 1/20, 1/40, 1/80, 1/160, 1/320, 1/640) of rabbit sera containing anti - type 1 fimbriae antibodies. The maximum inhibition of biofilm formation in terms of optical density (580 nm) was found in lowest dilution (1/10) (highest concentration of Abs). However, the minimum inhibition was observed in highest dilution of rabbit antisera (1/640) (lowest concentration of Abs). Here the inhibition occurs in a dose dependent manner as the biofilm formation increased dramatically with increasing in antisera dilution. The results also showed that there is a significant difference(P<0.05) among data treated with sera and data without sera and among serial dilutions.General urine examination and culture for urine that absorbed from test 2 and control was done (GUE) show that pus cell in urine was (1 - 2/HPF). There was no growth of bacteria in urine culture.The Histological section show that the Control and test 1 rabbit (have been immunized with fimbriae and adjuvant and injected with E.coli intra muscular) and Test 2rabbit (that has been immunized with fimbriae and adjuvant and injected with E.coli directly in bladder has normal epithelial cells and mucosa.
