Bacteriological & Serological study of Escherichia coli bacteria isolated from Urinary Tract Infections from women and it`s Resistance to Antibiotic

Abstract

The study was included 100 isolates of Escherichia coli from 350 samples from women with Urinary Tract Infections From different regions in Diyala Province. All samples were collected from 2013 / 10 / 15 to 18/2/ 2014.All bacterial isolates were identified by the biochemical cultural and microbial characteristics and confirmed by API-20E , VITEKA2system.The serological test was performed by slide agglutination test, and 19 Isolates with percentage (19%) gave positive results for the polyvalent antisera O126 ,O26, O111 ,O119 ,O55 .The sensitivity of these isolates were tested against (16) antibiotics, the results induct that E.coli had different resistance to the antibiotics : Augmentin , Aztreonam , Ampicillin , Co-trimoxazole , Chloramphenicol with the rates 100%, 93%, 92%, 89% and 86% respectively. The isolates were more sensitive to Ceftazidime, Gentamycin, Ciprofloxacin, and Cefixime with resistance rate 41%, 38%, 35% and 30% respectively. The antibiotics Imipenem and Tobramycin were more sensitive with sensitive rate 100% and 80% respectively.
