Abstract: اجريت الدراسة على300عينة سريريه مختلفة حصل عليها من الجروح والادرار والقشع والدم خلال الفترة من ايلول 2013 الى شباط 2014.منها 102(34%) لا يوجد نمو بينما 198(66%) نمت على وسط زرعي متخصص. شخصت عشرة عزلات من Acinetobacter baumannii من مائة وثمانية وتسعون من | Out of 300 various clinical samples obtained from wounds, urine, sputum, blood through the period from September, 2013 to February, 2014 of which 102 samples(34%) yielded no growth while 198 samples (66%) were positive growth on selective media. Ten isolates of Acinetobacter baumannii were identified among one hundred ninety eight of Gram - negative bacteria grown on MacConkey agar that was isolated from different clinical specimens in Al - Najaf Al - Ashraf province hospitals. A.baumannii identification depends on morphological, microscopic examination and biochemical tests as the initial identification. Also it was identified by both blood agar containing D - glucose and growth at 44?C. The final identification was performed by Api20E to confirm from all A.baumannii isolates..Distribution of A.baumannii among various clinical specimens where 4 isolates (40%) of wounds specimens and 3(30%) of urine specimens, followed by 2 isolates(20%) and one isolate(10%) of sputum and blood specimens respectively.The virulence factors of A.baumannii were studied, including bioflim formation, adhesion, capsule, hemolysin and protease, beta _lactamases production. The results indicate that 60% of A.baumannii formed the biofilm, 90% of isolates have ability to adhesion to epithelial cell and 70% of isolates was the capsule production, 80% of A.baumannii isolates able to produces beta _lactamases while all A.baumannii isolates cannot produce of both hemolysin and protease.The results showed variation in the resistance of these bacteria to antibiotics where all A.baumannii isolates 100% resistance to each of cefotaxime, Ceftazidime, ceftriaxon, piperacillin while 90% resistance toticarcillin - clavulanic acid, 50% resistance to tobramycin and 30% to ciprofloxacin. 20% of all isolates showed resistance to each of amikacin, Doxicycline, imipenem, meropenem.By using Combing Disc Test(CDT) method to detect Extended Spectrum ? - lactamases(ESBLs) and metallo ? - lactamases (MBLs) production.Where 90% of A.baumannii showed ability to produce of ESBLs while only 20% showed ability to MBLs production.The genotypic method was used to detect csuE, ompA genes and also some of ? - lactamases genes such as blaTEM, blaSHV, blaNDM - 1 by using Polymerase Chain Reaction technique.The results showed that 60% of all A.baumannii isolates produce phenotypic biofilm and 30% carry csuE gene of all isolates while 50% when compared with isolates that show phenotypic formation of biofilm and the distribution of gene among all clinical specimens where 50 %, 33.3% and 25% in sputum, urine and wounds specimens respectively while not present in blood specimens. The results showed that 40% of all A.baumannii isolates carry ompA gene while 44.4% when compared with isolates that show phenotypic adhesion and the distribution of gene among all clinical specimens where 100%, 50 %, 33.3% and 25% in blood sputum, urine and wounds specimens respectively.The outcomes showed 70 % of A.baumannii isolates carry blaTEM gene and 40% of A.baumannii isolates carry blaSHV gene while none carry of blaNDM - 1gene. When compared with phenotypic results of ESBLs, MBLs.The results of blaTEM, blaSHV genes become 77.7% and 44.4% respectively.

Abstract: Six Bifidobacterum isolates were isolated from fully breast - fed healthy infant faeces on reduced de Man Rogosa and sharp medium (MRS - C). Isolates identified on the basis of, colonial and microscopical properties, biochemical tests, and fructose - 6 - phosphate phosphoketolase enzyme (F6PPK) activity assay in cellular extracts. Carbohydrates fermentation profile used for identification of isolates to species level. All bacterial isolates diagnosed as Bifidobacterium genus where in this study B. adolescntis was the predominant species (50%), (B4, B5 and B6), followed by B. breve (B3), B. longum (B1) and B. dentium (B2) each one represent 16.67%.Bifidobacterium isolates were screened for their antagonistic effects against test organism, clinical isolate of shiga toxin producing E.coli O157 : H7 (STEC), using agar - well diffusion method. The isolates B3 and B6 showed clear inhibitory actions, 22 mm and 15 mm diameter of inhibitions zones, respectively. The rest of the tested isolates did not pronounce any inhibitory activity.B. breve in vivo antagonistic behavior and the possible protective effects against STEC was evaluated, using streptomycin treated murine model. Murine intestines was stably colonized orally with B. breve for 14 days, in conjunction mice were challenged orally with STEC, 103 CFU / mouse / day on day 8 of experiment. Bacterteriological analysis of mice faeces at time intervals, was indicated high levels of bacterial colonization were achieved in intestine by B. breve and STEC.Colonization of mice intestine by B. Breve did not inhibited STEC cells from proliferation during infection phase. Hence, the excretion level of STEC in faeces reached to 2.4 x 10 6 CFU/ g of faeces.STEC infected mice showed no severe clinical signs, characterized by hairloss, lethargy, paralysis of fore limbs, and shed of loose faeces. In the B. breve - colonized group, the mentioned clinical signs were almost completely inhibited, except the lethargic of some animals.Immunological studies showed an increase in the levels of sIgA by 2.7 - fold from that of blood IgA in B. breve - colonized mice while, reversed values were recorded in mice infected with STEC, blood IgA level was 1.95 - fold higher than that of sIgA.Histological changes in spleen, liver, kidney, and intestine tissues of mice were studied. The histological sections clarified the protective roles of B.breve, where no effective histological disorders were appeared in B.breve and STEC - colonized mice. In the STEC - infected mice, the pathological abnormalities within the kidney was the predominant, diagnozed as ulcers in the lining membranes, glomerular and tubular epithelium necrosis, without evidence of glomerular thrombi, mild damages was appeared in liver and spleen, and characteristic attaching and effacing (A / E) lesions appeared in the large intestine sections

Abstract: مرض قصور الشرايين التاجية هو النتيجة النهائية لتراكم اللويحات العصيدية ضمن جدران الشرايين التاجية مسببة نقص الاوكسجين وبالتالي حدوث مرض القلب الاقفاري. ويعتبر من الامراض الشائعة واحد الاسباب الرئيسية لحالات الوفاة في العالم. اضافة الى عوامل الخطورة التقلي | Coronary artery disease (CAD) is the end result of the accumulation of atheromatous plaque within the walls of the coronary arteries resulting in shortage of oxygen supply and ischemic heart disease (IHD). It was consider as one of the most common diseases and major causes of worldwide morbidity and mortality. In addition to traditional risk factors for cardiovascular disease, nowadays, accumulating evidence indicates that a variety of infectious agents may contribute to pathogenesis of CAD. The present study evaluated the anti - Helicobacter pylori IgG and IgA and the role of virulence factor of H. pylori cytotoxin associated gene (Cag A) and vacuolating associated cytotoxin (Vac A) as a risk factors for CAD.Eighty patients were divided into 2 groups : first group was 70 patients with CAD, the other group contained 10 patients with another coronary artery disease; they were admitted to Ibn Al - Bitar Specialist Center for Cardiac Surgery in Baghdad between October 2013 and January 2014. Ten individuals used as a healthy control group. All blood samples were tested biochemically such as glucose test, urea test, creatinine test and lipid profile test(cholesterol, triglyceride, LDL and HDL) and all of them showed normal results. The present study revealed that males were affected more than females (3 : 1); with no relation between their ages and bacterial infection.Serum IgG and IgA was Estimated by indirect immunofluorescent (IIF) whereas Cag A, Vac A and high sensitive C - reactive protein (hs - CRP) measured by enzyme linked immunosorbent assay (ELISA) and compared to control group results.The incidence of the anti - H.pylori IgG was highly significantly prevalent in CAD patients 78.57% (55/70), than in control group 0% (0/10), also a high significant difference in another CAD patient group 100%(10/10) as compared to control group 0% (0/10) (P? 0.01).Similarly anti - H. pylori IgA in CAD patients and another CAD patient groups showed highly significant increase when compared to control group 37.14% (26/70), 30% (3/10) and 0% (0/10) respectively (P? 0.01).The incidence of the CagA - positivity was significantly prevalent in mean value (2.74±0.19) in patients with CAD and another CAD patient group(2.72±0.31) than in control group (1.64± 0.16) (P? 0.05). Same result was observed with Vac A antigen; mean value of patient group showed significant increase (1.299 ± 0.04) when compared to controls group (1.41±0.13) (P? 0.05). Also significant increase found between another CAD patient group(1.79±0.17) and control group (1.41±0.13) (P? 0.05). Furthermore; the present study revealed significant differences of concentration levels between hs - CRP in CAD patient group (4.95 ± 0.38 µg/ml) as compared to control group (0.77 ± 0.06 µg/ml), as well as a significant differences found between another CAD patient group (3.96 ± 0.96 µg/ml) as compared to control group (0.77 ± 0.06 µg/ml) (P? 0.05).

Aspergillus niger Has been Isolated from these sample with 56% appearance in soil & 48% in sptum of TB pateints.these isolated were examined micro and macroscopically. purified Fungi was culture on potato dextrose broth, after incubation period polysaccharide antigen of A.niger cell wall was prepared for isolated from soil and TB patients suptum. Molish, protein and glucose test to provide that these antigen are polysaccharide, then immunuization of local rabbit of Orcyctalagus conninculus age 3 - 5 months & 1 - 1.5 Kg for males only (3 animals for each antigen) After the immunization period (one month) some of local and systemic immune response parameters (cellular and humoral) to test animals were studied and compared with control animals which immunized with normal saline. The results of study showed that the polysaccharide antigen isolated from these two strains lead to stimulate systemic humaral immune response which had been studied by using direct agglutination test for appendix immunoglobulin passive haemagglutination test (both were used to determined antibody titer), radialimmunodiffusion test in order to determine level of concentration of immunoglobulins (IgG, IgM) and complement part (C3, C4). where The results of direct agglutination titer of animals immunized with polysaccharide antigen 128 and 1 for control animals and heamagglutination tests titer of animals immunized with polysaccharide antigen serum (2560). These results were higher compared with control group titer (10) and this is also true for immunoglobulin and concentration of IgG, IgM for immunized animals compared to control one. In addition to that The concentration of C3 and C4 had been increased in immunized animals compared to the control. cellular immunological response had been measured by using rabbit Neutrophil Elastase Kit. The eresult show an increase in the level of phagocytosis in animals immunoized with polysaccharide antigen isolated from A.niger cell wall of TB pateints 0.37±0.03 pg/dl while decreased in animals immunoized with polysaccharide of soil A.niger 0.72294±0.25548pg/dl compared with control animals 0.6±0.16386 pg/dl. on the other hand the humaral adaptive immune response had been identified by measuring cytokine IL - 2, IL - 10 in serum rabbit, the level of IL - 2 in rabbit immunoized with polysaccharide antigen soure TB patients and soil is 5.4129±1.08979 and 4.2641±0.62997 pg/dl respectively compared with control animals 3.9327±0.55587 pg/dl. The level of IL - 10 had been dropped for immunized animals with A.niger of TB pateints and from soil 4.8762±1.15104 and 8.2632±4.31933 pg/dl while the control animals having the highest level 10.2576±5.23356 pg/dl among the groups. IgE concentration measured significant difference at p>0.05 in immunized animals of A.niger in both TB pateints and soil 1.1701±0.05811 and 1.0770±0.19355 ml/Iu compared with control where IgE0.8723±0.0849ml/Iu. Miotic index of bone morrow immunized and control animals show mean difference is signification at p>0.05.where the result demonstrate that the polysaccharide antigen fissed the bone marro cells compared to controlled one. In order to identify the viability of antigen in protection. challenge dose test made by injection animals with 108 spore/ml of A.niger conidia which prove their protection in immunized animals while the control animals undergo many morphological and behavioral changes after 5 - 7 days of their injection.I addition that the size of lung and spleen increased when compared with immunized one. The histological culture of lung and spleen of challenge test animals in order to identify the ability and speed of their body to evadicate and prevent infection, display that A.niger coloni appeared for control animals (6 rabbit) while disappeared in culture of immunized one. Skin test also performed to experimental animals which indicate that polysaccharide antigen of A.niger interact with hypersensitivity test of rabbit, where the level of late hypersenetivity increased clearly with propability of p>0.05 with the highest level after 24 hours of beginning test compared to controlled one.

Abstract: بحثت الدراسة جمع 100 مسحة من اطفال مصابين بالتهاب اللوزتين الحاد والمزمن ممن راجعوا استشارية الانف والاذن والحنجرة في مستشفى اليرموك التعليمي للمدة مابين كانون الاول للعام 2013 ولغاية اذار للعام 2014. وكانت نتيجة الزرع المختبري موجبة في 67 مسحة منها وبالا | In this study 100 swabs were collected from infected children with acute and chronic tonsillitis who attended at Al - Yarmook Teaching Hospital (Eear Nose Tonsils consultation clinic) from December 2013 until March 2014. The result of laboratory culture were positive in 67 samples. Depending on their cultural, morphological and biochemical characterization of bacterial isolates : (37.31%) of them were identified as Streptococcus pyogenes bacteria and the diagnosis is confirmed by the use of Remel Rapid STR System. Whereas (34.33%) belong to S.parasanguinis, (11.94%) S.mitis, (11.94%) S.oralis and (4.48%) S.thoraltensis were identification of them are confirmed by using Vitek - 2 System also. As well as Sensitivity test for S.pyogenes cultures for some of the antibiotics done and the results revealed that all cultures were sensitive to tetracycline and chloramphenicol drugs 100%, while it was different in their sensitivity for other drugs. According to age (2 - 13) years revealed the highest percentage of infection for both male and female, however the percentage of acute and chronic tonsillitis was higher in males than females. In this study, during investigation of the antagonist action of lactic acid bacterial isolates against these pathogenic bacteria, results revealed that the method of L.acidophilus discs gave a high inhibition zones with a diameter of 11.3 mm, while L.fermentum discs yielded a high inhibition zones with a diameter of 7 mm 24 hrs following incubation in comparison with well diffusion method by using suspension of L.acidophilus produced a high inhibition zones with a diameter 7.25 mm 48 hrs after incubation. L.fermentum suspension produced a high inhibition zones with 10 mm diameter 24 hrs following incubation. Also the study included measurement of the inhibition activity for bacteriocins produced by L.acidophilus bacteria against the pathogenic bacteria S.pyogenes on nutrient agar by well diffusion method in which results revealed stability of the bacteriocins effects under different PH (4, 5, 6) with percent (100, 60, 50)% respectively for 24 hrs at higher stability and the highest stability of bacteriocins during PH was 4 with percent 100%, while it lost a lot of its activity with acidic PH less than 2 and basal pH more than 8. During the study the effect of Nacl, Kcl and MgSo4 with different concentrations (1 - 5%) with constant inhibitory effect for bacteriocins produced by L.acidophilus against pathogenic S.pyogenes, The result revealed that Nacl had little effect in inhibition zone with 1&2% concentrations. The salt MgSo4 and Kcl showed reduction in the inhibitory activity with 1, 2, 3% concentration, however the higher concentration of salt caused great reduction as 5% concentration led to loss of inhibitory activity for bacteriocins completely.Also this study showed light on the inhibitory effect of probiotics suspensions against the adhesion property of S.pyogenes after treated with L.acidophilus and L.fermentum.where the Result shown that L.acidophilus inhibit the adhesion of S.pyogenes with percent 68.92% either L.fermentum inhibit the adhesion of this pathogenic bacteria to epithelial cell with percent 30.28%. The study is consisted of showed the inhibitory action for suspensions of L.acidophilus and L.fermentum on biofilm formation by S.pyogenes, it was noticed the action of L.acidophilus in the side more than from the action of L.fermentum. During the study of the effect of suspension and filter of L.acidophilus and L.fermentum on the production of Hemolysin enzyme by S.pyogenes, it was noticed that the ability of suspension belong to L.acidophilus and L.fermentum to reduce the diameter of hemolysis zone which was beta type more than the ability of filter L.acidophilus and L.fermentum to reduce of the hemolysis zone which was beta type.

Only 51(31.875 %) Staph. epidermidis isolates were obtained during a period from September 2014 to January 2015, depending on some biochemical tests and VITEK2 system. The Staph. epidermidis was given (gram stain, catalase , urase) positive, (coagulase, manital fermentation, oxidase, motility) negative, non haemolytic to human blood with some exception, most of the strain were able to produce biofilm, and (100%), (64.70%), (74.50%) resistant to penicillin G, ampicillin, and amoxicillin respectively. The Staphylococcus species identified during study were 44 (27.5%) isolates of Staph. aureus, 5 (3.125 %) Staph. haemolyticus, 4 (2.5 %) Staph. saprophyticus, 8 (4%) isolates other Staphylococcus spp. such as Staph. hominis ssp. hominis, Staph. capatis, Staph. xylose, Staph. simulanus, Staph. lentus, and 48 (30 %) from unknown genera. To isolate bacterioghages from sewage water, several sewage water samples were assayed using plaque assay of double agar overlay as a source of Staph. epidermidis phages. The bacteriophages were described depending on plaques size and shapes, phage 1 was the most predominant and frequent in the bacterial lawn and able to infect other S. species such as S. aureus. It has been selected to study it is titer, latent, rise period, and burst size were calculated. The effect of temperature, pH , and NaCl ions on it is original titer were studied.The results revealed a gradual decreasing in the phage titer with increasing dilution number. Latent period extended to (30 minutes) , while rise period was started with (40 minutes) extending to (60 minutes) , burst size was 2.346. Each temperature at several incubation periods , pH , and NaCl ions was significantly varied depending on phage titer. The optimum temperature was 40 ° C, while the 80 ° C was represented the inhibitor temperature. L.S.D. at level (0.05) for interaction was 39.552. The pH 6.5 - 7.5 represented the optimal pH for the best phage activity while the phage titer beginning to declining in above and below this range of optimal pH, L.S.D. at level 0.05 was 17.898 , the optimum NaCl ions concentrations were (0.1 M and 0.25 M), while the titer was significantly decreased with increasing the NaCl ion concentration in the culture solution, the L.S.D. at level 0.05 was (10.696). In conclusion of this study found that Phage1 was considered as predominant phage because of their ability to infect other Staphylococci species such as Staph. aureus.

Abstract: تناولت هذه الدراسة عددا من العضلات الهيكلية في نوعين من الطيور الطائرة (الحمام) وغير الطائرة (الدجاج). العدد الكلي للطيور المستعملة 30 طائرا, 15 من الدجاج و15 من الحمام تمت دراسة بعض الخصائص الفسلجية والنسيجية للالياف العضلية الحمر والبيض والوسطية وحساب | This study deals with a number of skeletal muscles in two types of birds ; flying (pigeon) and running (chicken) types. The total number of the studied birds was 30; 15 were chicken and 15 were pigeons. Some of the physiological and histological characteristics of the muscle fibers (red, white, and intermediate) , the percentage of fibers diameter in the studied muscles, and the change noted in the muscle weight with advancing age had been calculated. The species of the chicken in this study was Gallus domesticus , while the species of the pigeons was Columba livia domestica. The muscles that is used in the study were : pectoralis muscle, femortibialis, triceps, biceps brachii, extensor carpi radialis muscle, and gastrocnemius muscles in two age groups of birds; (3 - 6) months and (6 - 12) months in order to know the changes in the weights, numbers, diameters, and sizes of the muscle fibers that occur with advancing age. The aim of this study is to identify the three types of the muscle fibers their role in the muscle movement and the regions in which there is specific type rather than others. The results had shown that the skeletal muscles in birds consist of heterogenous mixture of the three types of muscle fibers (red, white, and intermediate) , and the white muscle fibers are the predominant type in the pectoralis muscle of both types of birds, and the size of white muscle fibers in the pectoralis muscle in the chickens in the first age group was 73.8%, and in the second age group was 82.9%. While in pigeons, the size of white muscle fibers was 75.5% in the first age group, and 75.4% in the second age group. In addition, the present study deals with the relationship between the muscles weights and the age of the bird in that the muscles show increased weight with advancing age in both types of birds and there were significant differences in muscles weight in both age groups (p?0.05), while the triceps muscle did not show significant difference regarding weight between the two age groups in the same type of birds. The results of the study also show the differences in the diameter of the muscle fibers, that is there was continuous increase in the diameters with advancing age and show significant differences (p?0.05) , but regarding pectoralis muscle there was no significant differences in diameters with advancing age in both types of birds. The results of the study also show that the pectoralis muscle was the largest muscle in the body of the bird, and the ratio of its weight to the total body weight was relatively large.

The two experiments were conducted at the field of College of Agriculture/Al - Qadisiya University during the period from 31/10/2012 to 14/3/2013. For the field experiment, dry and fresh leaves of Eucalyptus were used at the rate of 0, 2, 3, or 6 g dry leaves/Kg soil or at the rate of 0, 4, 8, or 12g fresh leaves/kg soil. Plant height, changes in height during plant life time - course, number of branches, number of flowers, and flower diameter were measured. In addition, chlorophyll content in leaves, anthocyanin in petals, dry weight, nitrogen percent, potassium and phosphorous content in leaves were also determined. For the laboratory experiment, ethanol extract, oil, terpenes, alkaloid, and phenols extracted from Eucalyptus leaves at different concentrations were used. Seed germination, coefficient velocity of germination, plumule and radical length, sugar, protein, melanodialdehyde, glutathione and proline content were evaluated. The results were as follow : 1. Ethanolic extract was negatively affect the percent and coefficient velocity of germination in addition to plumule and radicle length. The reduction in these parameters was greater at the highest concentration of the extract, especially in Calendula officinalis. 2. Treatment with oil extracted from Eucalyptus leaves caused a significant reduction in percent and coefficient velocity of germination, plumule and radical length. 3. Terpenes, alkaloids or phenols treatments at different concentrations resulted in significant reduction in percent and coefficient velocity of germination, plumule and radical length. The reduction was increased as the concentration of the treatments increased. 4. Plant height decreased significantly due to the treatment with dry or fresh Eucalyptus leaves, the reduction in plant height increased as the concentration of the treatment increases in all plants except Asteriscus graveolens plant which showed that the small concentrations of both treatments. It was close to ward in an increase in plant height. 5. Number of branches also significantly decreased when ornamental plants treated with dry or fresh Eucalyptus leaves; the Calendula officinalis plant was the most affected. 6. For the changes in ornamental plants height, as a result of treatment with dry or fresh leaves of Eucalyptus, during life time - course, it was clear the growth curve was close to the S - shape growth curve with obvious significant differences for most treatments compare to control. 7. Dry weight percent was significantly affected in all ornamental plants when they treated with dry or fresh Eucalyptus leaves, If decreased with the concentration of the treatments increased. 8. It was obvious that treatment with dry or fresh Eucalyptus leaves resulted in significant reduction in flower number and flower diameter. Number of flowers decreased as the concentration of the treatments increased. on the other hand, flower was diameter increased as the concentration of the treatments increased, but in both cases it was less than the control. All one obvious that reducing significant in flower diameter, It was reducing great in low levels. 9. Chlorophyll content was also decreased in leaves, while anthocyanin content in petals was increased when the ornamental plants treated with dry or fresh Eucalyptus leaves. 10. Nirogen percent, phosphorus and potassium content in leaves of the four ornamentals decreased when they treated with dry or fresh Eucalyptus leaves. 11. Using terpenes, alkaloids and phenols caused significant increase in sugar content in leaves of the ornamentals, reaching its highest values at the highest concentration of the terpenes. For protein content, it was gradually decreased as the terpens, alkaloids and phenols concentrations increased in Calendula officinalis. In Tagetes patula, protein content was noticeably increased with the increasing in concentrations of the treatments. 12. Malondialdehyde, glutathione and proline content increased significantly in Calendula officinalis and Tagetes patula plants when they treated with terpenes, alkaloids or phenols. 13. Interaction between treatments concentrations and kind of plants had significant effect on all parameters measured.
