المستخلص:
جمع 60 نموذجا من عينات بول وسط المجرى من المرضى الراقدين في المستشفى الذين يعانون من اخماج المجاري البولية من مستشفى اليرموك ومستشفى الكرخ ومستشفى القديس رافائيل/ الراهبات للمدة من 27 شباط 2014 ولغاية 25 اذار 2014، وقد اظهرت نتائج الزرع البكتريولوجي الحصو | Sixty mid - stream urine specimens were collected from patients presented with urinary tract infections whom attending Al - Numan, Al - Yarmouk, Al - Karkh, and Saint Raphael/Al Rahibbat hospitals in Baghdad for the period February, 27th to March, 25th 2014. Bacteriological culture identified fifty (80.33%) isolates as E. coli depending on cultural and biochemical characteristics as well as Api and Vitek 2 automated systems. However, 82% of isolates developed ? - hemolysis on blood agar plates.Susceptibility of all isolates against seven commonly prescribed antibiotics were investigated and 96, 82, 84, 92, 92, and 56%. of isolates were resistant to ampicillin, ampicillin/sulbactam, amoxicillin/clavulanic acid, cefalothin, imipenem, and meropenem, ceftazidime, respectively.Concomitantly, ? - lactamase production was detected phenotypically by disk replacement method. The results showed that 82% of all isolates have the ability to produce ? - lactamase. Interestingly, correlation coefficient between ? - lactamase and hemolysin production was 0.99.Using microtiter plate method, all E. coli isolates were tested for their ability to form biofilm. The results revealed that 36, 54, and 10% of isolates formed biofilm with variable thickness; weak, moderate, and strong, respectively.Alongside with previous findings, blaCTX - M - 2, blaVIM, blaTEM, and blaPER were identified in 18, 12, 10, and 4, respectively. Nevertheless, none of blaOXA - 1, blaOXA - 4, blaOXA - 30, blaIMP, blaCTX - M - 1, blaCTX - M - 9, blaKPC, and blaSHV. The isolate number 11 harboured the highest number of genes (blaTEM, blaVIM, and blaPER) among all tested isolates. Twelve albino mice was divided randomly into four groups comprising A through D injected with ceftazidime at sub MIC, E. coli 11, E. coli 11 with ceftazidime solution, and standard strain, respectively.Histopathological sections did not show any changes in respeuct to group A. however, group C suffered signs of infection less than those appeared in group B sections. Simultaneously, group D suffered intense histpathological changes more than other groups infected with resistant isolate.
