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

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: تم التحري عن بكتريا السالمونيلا في 520 عينة من الاغذية المحلية في مدينة تكريت, وجدت هذه البكتريا في 26 عينة (5%), كانت اعلى نسبة لتواجدها في عينات اللحوم المثرومة (2.5%) والتي تمثل 16.25% من العينات الكلية للحوم المثرومة المدروسة.عزلت السالمونيلا من عي | The presence of Salmonella spp. was investigated in 520 local food samples in Tikrit city, Salmonella was found in 26 samples (5%), with the highest presence in minced meat (2.5%) which was represented 16.25% of all minced meat samples. Salmonella was isolated from chicken's meat at a percentage of 3.75%, and same percentages for meat slices samples, egg cortex and chicken's blood represented 5% for each one, and isolated too from vegetables and cheese at a percentage of 2.5% for each one. No Salmonella has been detected from sweet, yoghurt and egg content. Six Salmonella species were isolated, S. typhimurium was to be the most frequent and represented 42.30% of positive samples, then S. enteritidis and S. anatum in 34.61% and 11.53% respectively, but S. agona, S. typhi and S. arizona existed in a percentage about 3.84% for each one. Also, all the isolated species showed their own serological formula. The selective medium Tetrathionate broth (TTB) was found to be superior for isolation of Salmonella than Selenite cystine broth (SCB), the former positivity was 96.2% and 88.5% respectively. For test of better selective medium for isolation, TTB was found to be more suitable for isolation of S. anatum, while SCB was better for isolation of S. arizona.All the six isolated Salmonella species showed high sensitivity to Ciprofloxacin (5?g) and moderately sensitive to Chloramphenicol (30?g), while they showed high resistance to three antibiotics Amoxicillin (30?g), Nalidixic acid (30?g) and Pipracillin (100?g). They showed resistance with different percentages to the other tested antibiotics : Ampicillin (10?g), Gentamicin (10?g), Streptomycin (10?g), Tetracycline (30?g) and Trimethoprim (25?g).

This study aimed to isolation and identification the species of Pseudomonas and metabolic efficiency test in the analysis of petroleum hydrocarbon compounds and measure the effectiveness of antagonism in resistant pathogenic fungi to tomato plant. Thirty four isolates were identified, the Pseudomonas spp. was the highest frequency with 22 isolates. These isolates distributed to 16 isolates of pseudomonas aeruginosa and 6 isolates of pseudomonas fluorescens. Also this study included isolation of two pathogenic fungi which were Alternaria alternate and Fusarium solani in tomato plant. Statistical analysis revealed significant differences at (p<0.05) between the bacterial isolates in their analysis of hydrocarbon compounds, when the optical density measurement as an indicator of the effectiveness of growth on hydrocarbon sources. All isolates showed different optical densities were highest isolation of pseudomonas aeruginosa isolated from urinary tract infections as optical density amounting to 0.23nm. Also showed an increase in electrical conductivity values for all isolates within the incubation period, the highest value to the hospital (1) isolate with 12.8 mc/cm in the third week of the incubation, But decreased in the sixth week to 8.7 mc/cm and all isolates showed a good effectiveness of electrical conductivity in the third week and noted significant differences (p<0.05) in electrical conductivity values for isolates compared with control of 7.2 mc/cm. The results of the DNA electrophoresis of the all isolates contain the two genes (C23O and rhIB) which they code for the production of hydrocarbon - degrading enzymes. In Bio - antagonism experiments noted that all isolates were inhibitory to the growth of two pathogenic fungi and stimulating the growth of tomato plants in glass and field experiments through increase germination, vegetative ratio and root length and increased weights with significant difference at (p<0.05)with seed treatment with fungus only. The best isolates increased in germination were pseudomonas aeruginosa hospital isolate and pseudomonas fluorescens generating isolate which had stimulated germination rate to 76% with significant difference when compared with the control of Alternaria alternata and Fusarium solani which germination rate was 36 and 40 respectively. Pseudomonas aeruginosa which isolated from soil was more efficient in increasing the length of the stem, the stem height was 7.53 cm compared with the control treatment with F. solani, the stem height was 5.7 cm. Pseudomonas aeruginosa hospital which led to an increase in the length of the total root to 3.66 cm compared with the control treatment with F.solani at 1.53 cm. The increase in fresh and dry weights of Total vegetative reached 0.64 gm and 0.065 gm respectively when the treatment of seed contaminated with F.solani fungus and pseudomonas aeruginosa hospital isolate compared to the control which the weights were 0.11 g and 0.011 gm respectively. The highest increase in fresh and dry weights of total root of 0.057 gm and 0.0072 gm respectively when treated seeds contaminated with the F. solani with P. fluorescens hydrocarbon contaminated soil isolate compared with control that the fresh and dry weights was 0.032 g and 0.0017 g respectively. The highest value of stem length registered when treating seed with A. alternata which was 7.5 cm when treating seed contaminated with A. alternata by P. fluorescens isolated from soil contaminated with hydrocarbon compounds. The lowest value of stem length was 7.3 cm for the treatment of seeds contaminated with the A. alternata by P. aerugionsa isolated from the drainage water compared with control treatment (seeds contaminated with A. alternata) which stem length was 6.33cm. As for the fresh and dry weight for total vegetation was the highest value of 0.8 gm and 0.793 gm respectively when the treatment of seeds contaminated with the A. alternata P. aerugionsa isolated from urinary tract infections and the lowest value of fresh weight was 0.61gm for total vegetation when treated seeds contaminated with the A. alternata by P. aerugionsa isolated from soil non contaminated with hydrocarbon compounds and 0.069 gm when treated seeds contaminated with the A. alternata by P. aerugionsa which Isolated from drainage water compared with control treatment which were 0.15 gm and 0.0014 gm of fresh and dry weight for total vegetation, respectively. As for fresh and dry weight of total root were the highest value 0.071 gm and 0.008 gm respectively, when the treatment of seeds contaminated with the A. alternata by P. fluorescens isolated from soil contaminated with hydrocarbon compounds. while the lowest value were 0.058 gm and 0.0065 gm when treated seeds contaminated with the A. alternata by P. aerugionsa isolated from soil non contaminated with hydrocarbon compounds compared to control treatment (seeds contaminated with the A. alternata only)which the fresh and dry weight values for total root were 0.046 gm and 0.0018 gm respectively. When antagonism study in the glass field, the highest percentage of inhibition of the growth of the F. solani on PDA and cetramide agar were 42% and 61% respectively, when treated with P. fluorescens generator isolate. While the bacterial antagonism with A. alternata on PDA media, the highest percentage of inhibition 51% when treated with the transaction P. fluorescens generator isolate on PDA media. Generally, the treatment of pathogenic fungi with biological control bacteria had reduced the percentage of infection and increase the percentage of germination.

The S. ferax species is more apparently presented in (February, 2014), the number of samples was 10. The less presence was in (April, 2014), the number of samples was 2. The results showed that the number of isolation of Saprolegnia spp. study area as it was S.parasitica species in were 6 in rivers, 2 in lakes, and 3 in fishes. The second species, S. ferax showed number of isolations which were 10 in rivers, 8 in lakes, and 2 in fishes. The PCR examination has used to detect the rDNA gene which responsible for proteases gene and whether it is found in the two species of fungi. The express way has been used to extract DNA and according to the instructions of manufacturer company. The concentrations of DNA in first species were 121.8 - 73.0 mcg/microliter and purity 1.87 - 1.80.In the second species the concentrations of DNA were 2360.4 - 166.9 mcg/microliter and purity 2 - 1.75. The results, by using PCR technique, showed that the percentage of protease in first species was 25% in rivers. In lakes and fish was 100%.Concerning the second species, the percentage of enzyme was 42% in rivers, 40%in lakes, and 50% in fishes. It can be concluded that there is a diversity in fungi species with respect to study areas and enzyme secretion in the stages of fungi infection. The enzyme is more apparently found in S.parasitica species compared with S.ferax species.

Abstract: من مجموع مئة عينة سريرية جمعت من مصادر مختلفة شملت الحروق والدم والجروح ومسحات انفية, تمكنت 90 عزلة من النمو على اكار المانيتول الملحي , ومن بينهم 40(44.4 %) عزلة عائدة لبكتريا المكورات العنقودية المنتجة للانزيم المخثر للبلازما و50 (55.5%) عائدة لبكتريا ا | Out of one hundred clinical samples were taken from different sources which include burns, blood cultures, wounds and nasal swabs infections ; 90 isolates developed growth on mannitol salt agar. Among these, 40 (44.4%) were Coagulase positive (Staphylococcus aureus) isolates, 50 (55.5%) belong to coagulase negative staphylococci in which Staphylococcus epidermidis isolates were 30(60%). The pattern of antibiotic susceptibility of Staphylococcus epidermidis isolates to 12 antibotics (Amoxiclav, Ceftazidim, ciprofloxacin, clindamycin, Erythromycin, Gentamycin, Imipenime, Penicillin G, Tetracycline, Rifampin , Methicillin, and Vancomycin) were determined using disc diffusion method. The results revealed that resistance to Penicillin G10 and Amoxiclav (Amoxicillin - clavulanic acid) were 100%, Methicillin were 93%, Erythromycin were 90%, Gentamycin and Clindamycin were 70%, Tetracycline and ceftazidim were 75%, Ciproflaxacin were 60%, Rifampin were30%. 95% of S.epidermidis isolates were sensitive to Imipenim and 5% of them were intermediate resistant, while these isolates showed 90% sensitivity to vancomycin. 19 isolates were multidrug resistance. Minimum inhibitory concentration of S.epidermidis isolates to vancomycin, was determined. The results revealed that (12) S.epidermidis isolates (40 %) were vancomycin resistant, the MIC of them were between 256 ?g\ml and 32 ?g\ml, (4) S.epidermidis isolates (13.3%) were intermediate resistance, the MIC to 3 of them were 16 ?g\ml and the last was 8 ?g\ml. Some virulence factors of VRSE and VSSE were detected including the hemolysin, protease, lipase and urease. The S. epidermidis isolates were produce hemolysin, protases, lipase and urease, were 100%, 100%, 25%, 100% respectively in VRSE, while in VSSE 100%, 100%, 60%, 100% respectively. The isolates were subjected to polymerase chain reaction (PCR) technique in monoplex pattern to amplify resistant incoding gene : the vanA, vanB and autolysine gene aae gene. The results by this study showed that 12 (40%) S. epidermidis isolates gave the implicone size (1030 base pair) of the vanA gene. However the results of MIC and PCR were similar but no any isolates gave product for presence of vanB gene. All S.epidermidis were able to produce implicone size(858bp) of aae gene. The effect of vancomycin resistant S. epidermidis on cell autolysis activity was detected by whole cell autolytic assay.The results revealed that there was significant difference among three isolates, the VSSE isolate (S.epidermidis 22) have the highest autolytic activity in the presence of antibiotic, followed by the VRSE isolate (S. epidermidis 1) and the VISE isolate (S. epidermidis14) which was the lowest autolytic activity with the presence of antibiotic. The result of transmission electron microscope (TEM) showed that the VRSE isolates (S.epidermidis 1) have thicker cell wall followed by VISE (S.epidermidis 14) isolates.However, the VSSE (S.epidermidis 22) didn't showed any cell wall thickening.

Therefore this study includes the evaluation of the immune status in sera of Babylon governorate displaced and residents with specific aspect for isolation and identification of measles virus from suspected cases. The immune response was evaluated by means of ELISA test (enzyme linked immunosorbet assay) for titration of IgM and IgG immunoglobulin level, in addition to evaluation of perforin level in the sera of 90 measles vaccinated individuals included in this study (50 displaced and 40 residents) from different areas in Babylon governorate, that were collected during the period extent from January up to April of 2016. Data about individuals were fixed according to information of formula including age, sex, geographical location, place displace of displaced and the vaccination date. Successful virus isolation from suspected cases on two types of cells culture included Vero cells line and chicken embryo fibroblast was carried. The titer of the isolated virus on Vero cell line reached (105.8 TCID50 / 0.1ml),which was higher than the titer of the virus isolated on CEF which reach (105.4 TCID50 / 0.1ml) after the third passage of the virus. The isolated virus was confirmed by indirect immunofluorescence technique.The age of subjects included in this study ranged from <1 year up to 24 years old. The results revealed that 15 (30%) have positive IgM index in sera of displaced, whereas residents sera sample shown only 6 (15%) positivity. Howover, all 90 (100%) subjects of both groups showed positive IgG index. The results of the present study showed that there were no significant difference of perforin level in sera of refugees and residents at p<0.05.Assaying of immune response against measles virus by measuring IgM immunoglobulin in sera of vaccinated displaced and resident with measles vaccine reflected a highly significant difference between two groups which reached 0.43 mIU/ml in sera of displaced in comparison with residents sera which reached 0.34 mIU/ml. The result showed also high significant differences in IgM between females and males. The females sera IgM levels of displaced and residents were higher than its level in males sera which reached 0.47 mIU/ml and 0.35 mIU/ml, respectively, in comparison with male sera level which reached 0.40 mIU/ml and 0.32 mIU/ml, respectively. According to age group, the highest IgM value was recorded in displaced and residents sera in age group 10 - 14years (0.50 mIU/ml) and 5 - 9years (0.36 mIU/ml) respec - tively. Whereas the lowest IgM serum value was detected in age group <1 year (0.34 mIU/ml) and 15 - 19years (0.31 mIU/ml) for displaced and residents subjects. According to geographical location, the highest IgM level was detected in sera of displaced from Tal Afar city (0.44 mIU/ml) followed by displaced from Ramadi (0.41 mIU/ml) and the lowest IgM value was detected in sera of displaced from Mosul city (0.33 mIU/ml). Whereas the highest IgM value in sera of residents in the subjects of Al - Mahaweel city (0.37 mIU/ml) followed by subjects of Hilla and Al - Qasem city (0.29 mIU/ml and 0.28 mIU/ml) respectively. For IgG serum immunoglobulin the results revealed that there was no difference in significant levels in both group population. But according to age groups significant difference between displaced and residents was detected at p <0.05 in which the 1 - 4 years old showed the highest IgG serum level in both group (1.98 mIU/ml and 2.18 mIU/ml) respectively. While the lowest IgG sera value was recorded in displaced age group of < 1 year old (0.60 mIU/ml) compared with residents age group of 20 - 24 years old (1.65 mIU/ml).It could be concluded that the results showed that the displaced do not have any effect on the residents of the province of Babylon for measles as a result of the good immunization by Babil Health directorate following to the Ministry of Health.

Abstract: اعتلال الكلية السكري هو السبب الرئيسي للمرض الكلوي المزمن وويرتبط ذلك مع زيادة وفيات مرضى القلب والاوعية الدموية. التعريف الكلاسيكي لاعتلال الكلية السكري هو زيادة افراز البروتين في البول. وتتميز المرحلة المبكرة للمرض عن طريق زيادة صغيرة في افراز الزلا | Diabetic nephropathy (DN) is the leading cause of chronic renal disease. It is associated with increased cardiovascular mortality. The DN has been classically defined as increased protein excretion in urine. Early stage is characterized by a small increase in urinary albumin excretion (UAE), also called microalbuminuria or incipient DN. More advanced disease is defined by the presence of macroalbuminuria or proteinuria. The latter is classically named overt DN.This study was planned with the aim of evaluate the levels of urinary Monocyte Chemoattractant Protein - 1(MCP - 1), interleukin (IL - 18), Osteopontin and Nephrin at diabetic nephropathy and its correlation with the parameters in Iraqi type 2 diabetic subjects and to explore the impact of albuminuria and duration of the diabetes on fine glomerular architecture using podocyte injury related marker (Nephrin) in urine. This may explore the more specific, and sensitive early biomarkers for nephropathy in diabetic patients and could help the physicians in controlling the occurrence of renal failure.Sixty Iraqi type 2 diabetes mellitus patients attending the National Diabetes Center for Treatment and Research at Al - Mustansiriyah University during the period October 2014 - June 2017 were recruited for this study. For the purpose of comparison, 20 control subjects matched for age, gender and ethnic background were also included. The patients and controls were characterized in family history of diabetes, diabetic nephropathy groups divide by used Albumin to creatinine ratio. The patients were also assessed for duration of disease, fasting serum glucose, and serum creatinine and blood urea.The mean urinary level of MCP - 1 (15.38±15.50 vs. 6.10±7.23pg/ml) and IL - 18 (35.90±16.67 vs. 23.55±12.67pg/ml) and osteopontin (337.15±257.06 vs. 174.11±183.65ng/ml) and nephrin (100.01±88.66 vs. 52.23±19.61ng/ml) were significantly higher in T2DM patients as compared to controls.The mean levels of urinary MCP - 1, uIL - 18 and osteopontin in macroalbuminurea group of patients were significantly higher than those in normoalbumine ( p < 0.008, p< 0.0001 and p< 0.03 respectively), and only of the Nephrin in the normoalbuminurea group of patients showed significant increased level as compared to the controls (52.23±19.61 vs.75.05±37.8 ng/ml) (p<0.022).The duration of disease showed an increase in mean of urinary level for all the markers MCP - 1, IL - 18, osteopontin and nephrin (17.01±18.09 vs. 19.76±21.30 pg/ml, 29.24±15.98 vs. 42.98±17.25pg/ml, 321.1±291.05 vs. 409.05±210.0ng/ml, 99.40±48.40 vs. 79.21±44.23 ng/ml) respectively, in late duration of disease as compared with early duration of disease except in Nephrin showed the early duration of disease higher than the late duration of disease (99.40±48.40 vs. 79.21±44.23), although the differences were not significant.The Receiver operating characteristic (ROC) curve analysis for all markers MCP - 1, IL - 18, Osteopontin and Nephrin levels (MCP - 1 = 0.72, IL - 18 = 0.71, Osteopontin =0.70 and Nephrin =0.72) for early diagnosis and detection of DN revealed that the cut - off value of uMCP - 1 was 6.23 pg/mg with 70% sensitivity and 75% specificity; whereas, the cut - off value of u IL - 18 pg/ml was 23.69 ng/mg with 80% sensitivity and 59% specificity and Nephrin was 49.5 ng/ml with 78% sensitivity and 55% specificity. uOsteopontin was 182 ng /ml with 68% sensitivity and 69% specificity.The linear correlation revealed a significant positive linear correlation between urinary MCP - 1, IL - 18, Nephrin and A : C ratio, also showed a significant negative linear correlation between urinary MCP - 1, IL - 18, osteopontin and GFR.In conclusion the Nephrin may be considered as potential diagnostic and prognostic biomarker a for the early detection and progression of diabetic nephropathy while the uMCP - 1, uIL - 18 and uOsteopontine may be considered as potential prognostic biomarkers for the diabetic nephropathy. The duration of disease also affect investigated biomarkers suggesting the long term effect of hyperglycemia

Abstract: Prostate cancer is the most common malignancy and the second leading cause of cancer related death among males worldwide. Prostate cancer developed in prostate , a gland that is located below the bladder and just in front of rectum.Inflammation is a fundamental physiological process that can arise in any tissue in response to traumatic, infectiousor autoimmune injury. Transforming growth factor beta one (TGF - ?I) is a potential regulator of prostate cancer cell growth that signals through a heteromeric complex composed of type I and type II receptors.TGF - ?R II is an important receptor , because TGF - ? bind to receptor II to initiate it's signaling, then receptor II recruits receptor I to initiate signal transduction. Interleukin - 17 (IL - 17) is a pro - inflammatory cytokine produced by T - helper 17 (Th17) cells contributes toboth the processes by playing a dual role in the antitumor immunity. On one hand, IL - 17 encourages an antitumor cytotoxic T cell response leading to tumor regression. On the other hand, by promoting angiogenesis and egress of tumor cells from the primary focus, so IL - 17 promotes tumor growth.This study was carried out to establish the correlation between expression of Transforming growth factor beta one(TGF - ?I), Transforming growth factor beta receptor one (TGF - ?RI) and Transforming growth factor beta receptor two (TGF - ?RII) and prostate cancer progression. Also to establish the role of IL - 17 in prostate cancer development.The study consisted of 16 patients with poorly differentiated malignancy (PDM) ,whose age ranged (48 - 89) years, with mean age of (71.2) years , and 25 patients with moderately differentiated malignancy(MDM) , whose age ranged (31 - 83) years , with mean age of (66.6) years , and 46 patients with benign prostatic hyperplasia (BPH) , whose age ranged (27 - 85) years , with mean age of (64.3) years. Allpatients were diagnosed surgically by consultant physicians in Baghdad hospital for specialist surgeries , Al - Yarmook teaching hospital ,as well as AL - Hilla teaching hospital , and 20 normal tissue sample taken from cadaver, whose age ranged (17 - 28) years , with mean age of (21.8) years , where chosen as a control group. The work was conducted in Iraqi center for cancer and medical genetic researches. The study were performed during the period from March 2014 to December 2014).Immunohistochemistry (IHC) technique was used to detect the level of expression of TGF - ?I , TGF - ?RI , TGF - ?RII and IL - 17 protein in tissues of patients and healthy control groups.The current study revealed that there was significant difference in mean levels of TGF - ?I protein expression between each of poorly and moderately differentiated malignancy compared with healthy control subjects with P - value of 0.001 , but there was no significant difference in mean level of TGF - ?Iprotein expression between benign prostatic hyperplasia and healthy control subjects with P - value of 0.398. Also there was no significant difference between poorly and moderately differentiated malignancy in mean level of TGF - ?I protein expression.TGF - ?R1 protein was expressed in 3 (18.7%) and 14 (56%) of poorly and moderately differentiated malignancy respectively , with weak immunostaining reaction was the most frequent score. There was significant difference in mean level of TGF - ?RI protein expression among all studied groups. TGF - ?RII protein was expressed in 6 (37.5%) and 22 (88%) of poorly and moderately differentiated malignancy respectively ,with weak immunostaining reaction was the most frequent score. There was significant difference in mean level of TGF - ?RII protein expression among all studied groups.IL - 17 immunohistochemical expression was detected in tissues of all studied groups , the results showed that moderate immunostaining reaction was the most frequent score among them. There was significant difference in mean levels of IL - 17 protein expression among all studied groups.We concluded that there was statistically significant association between the loss ofexpression of TGF - ?1 signaling receptors, especially TGF - ?RI, andincreasing grades of malignancy in prostate cancer. These resultssuggest a potential mechanism for prostate cancer cells toescape the growth inhibitory effect of TGF - ? and thus, leadingto a more malignant phenotype.

Abstract: تعتبر عزلات جراثيم التدرن المقاومه للادوية من المشاكل الرئيسية في معالجة مرضى التدرن حول العالم. , ولاهميته اجريت هذه الدراسة لتسليط الضوء اكثر حول الحساسيه الدوائية بواسطة الطرق المختبرية التقليدية وعلى الوسط الصلب ومقارنته مع الطرق التشخيصية المختبرية ا | Drug resistant tuberculosis remained as major problems in the treatment of tuberculosis patients in the world. A prospective study was conducted to evaluate drug susceptibility testing (DST) by classical methods on solid media as compared with advance and molecular Laboratory diagnostic methods (Bactec MGIT 960 and GeneXpert MTB - RIF ). The study included the estimation of the first line anti - TB drugs, including (Rifampicin,Isonizid,Streptomycin and Etambutol) by solid media (Lowenstein - Jensen medium) and Bactec MGIT 960 system. In addition, the use of rapid molecular diagnostic method by GeneXpert MTB/RIF assay. Seventy five TB patients attending the National Reference Laboratory of Tuberculosis /medical city - Baghdad from December 2015 to June 2016 were included in this study. Patients were classified into two main groups : selected MDR patients, which were referred from different hospitals and health respiratory center in Iraq, represented 46 in order to compare different laboratory methods to detect of DST isolates, while 29 were randomly isolated and identified , the study matched by age and gender were also included. This study revealed that the drug resistance tuberculosis to Rifampicin was 47 (62.7%), Isonizid 41 (54.7%), Streptomycin 42 (56.0%) and Ethambutol 38 (50.7%). Respectively , on the golden stander in which solid media were used.The molecular and advance technique (GeneXpert and Bactec MGIT 960) as applied to estimation of drug resistance tuberculosis, the results of drug susceptibility testing (DST), as showed highly sensitivity and Accuracy, when compared with golden stander( LJ media) especially in detected of primary drugs (Rifampicin and Isoniazid) and showed lower sensitivity and accuracy to detected of the secondary drugs (Streptomycin and Ethambutol). The Multiple drug resistance (MDR - TB) case from selective samples was found to be almost similar to that found in other countries of the middle east and other regions in the world. While in the randomly identified samples, the rate of MDR - TB was lower than the referred (previously treated) cases.The GeneXpert MTB - RIF system is rapid molecular methods that used in many countries to identify of MTB and Rifampicin detected during 2 hours only, that used in this study. The high Rifampicin resistance and other drugs of local isolates could be due to abuse of the drug,defaulter and relapse of retreating cases (previously treated).

Abstract: يهدف هذا البحث الى دراسة بكتريا المكورات العنقودية السلبية التخثر, وشملت الدراسة جمع120 عينة ادرار من المرضى المصابين بالتهاب المجاري البولية من الاشخاص المراجعين والراقدين في مستشفى بابل للنسائية والاطفال ومستشفى الحلة التعليمي وللفترة من كانون الاول 201 | This work aims to study coagulase - negative Staphylococci, which included 120 urine sample were obtained from patients suffering from urinary tract infection; who attained to Babylon Maternity and Pediatrics Hospital, and Al - Hilla General Teaching Hospital, during the period from December 2015 to March 2016), they were diagnosed as having UTI by the Urologists. The samples were analyzed for any signs of infection and immediately inoculated on blood and MacConkey agar media plates. All plates were incubated aerobically at 37 ?C for 24 - 48 hrs.Results of morphological and biochemical characterization revealed that out of total of 120 urine samples, 110 showed positive culture, among them 37 isolates are belonged to coagulase - negative Staphylococci, other 73 isolates belonged to other bacterial genera.Molecular detection of coagulase gene (coa) was done for all CoNS isolates. The results showed that 28/37 isolates (75.67%) were positive for this marker, distributed as follows : S. epidermidis gave 15 isolates, S. saprophyticus gave 9 isolates and S. haemolyticus gave 4 isolates.Also, molecular investigation of fnb A and B genes are carried out for all CoNS isolates by using specific PCR markers. 13/37 isolates (35%) were positive for fnb A gene, as 6/13 of S. epidermidis, 5/13 of S.saprophyticus and 2/13 of S. haemolyticus have this gene in their genome. On the other hand, only 4/37 isolates gave positive result for fnb B gene; as 2 isolates of both S. saprophyticus and S. epidermidis have this gene in their genome.Moreover, sec gene also was investigated in CoNS isolates. The results showed that all CoNS isolates are free from this gene.Regarding urease enzyme production, S. epidermidis and S.saprophyticus isolates were found to be urease positive, while S.haemolyticus isolates display urease negative.To demonstrate the ability of bacteria to form struvite stone, urine samples obtained from healthy individuals were used. It was found that struvite stone was formed by S. epidermidis and S. saprophyticus isolates.Moreover, susceptibility to 10 antibiotics were tested by using disc diffusion test (DDT). S. epidermidis was showed 100% resistance for each Methicilline, Ceftriaxone, Ceftazidime and Cefoxitin. Also, it show high resistance 94%, 88%, 88%, 76%, and 59% for Impenem, Gentamycin, Pipracillin, Ciprofloxacin and Amikacin respectively. However, S. epidermidis showed low resistance (6%) for Vancomycin. So, all S. saprophyticus isolates showed high resistance (100%) to each Pipracilline, Ceftriaxone, Methicillin, Ceftazidime and Ciprofloxacin. It showed high resistance (92%) for each Vancomycin and Imipenem, and (83%), (75%), (75%) for Cefoxitin, Gentamycin and Amikacin respectively. In addition to that, all S. haemolyticus was showed (100%) resistance for each Ceftriaxone, Pipracillin, Methicilline, Ceftazidime and Cefoxitin. Also, showed high resistance (75%), (63%) and (50%) for Gentamycin, Amikacin and Ciprofloxacin respectively. While it was showed low resistance (13%) to Vancomycin.
