Urinary tract infection : Significant bacteruria and candiduria in diabetics and non-diabetic patients


and their susceptibility tests to selected antimicrobials in both diabetics and non-diabetic patients. Methods : A total of 134 urine specimens, 66(49.3%) were obtained from patient admitted to Ramadi General Hospital in Ramadi and 68(50.7%) from the community setting during the period from April to September 2002. General Urine Analysis and semi-quantitative culture technique of urine were performed .Result : Out of 134 urine cultures, 121(90.3%) showed significant bacteruria . Thirty nine out of 56(69.5%) of hospitalized patients and 13 out of 65(20%) of non- hospitalized patients were diabetics while the remaining were non-diabetics . Further, in diabetic community acquired infection (CA) , Escherichia coli was the most common 10(76.9%) while Klebsiella spp . 15(38.5%) was the most common isolate in hospital acquired infection (HA) . In non-diabetics, Escherichia coli was the most common in both CA and HA, 24(38.0%) and 4(20%) respectively. Furthermore, significant candiduria was found in diabetic HA 11(28.2%) and 9(81.8%) of them harboring urinary catheter in contrast with non-diabetic HA, 6(30%). The isolated bacteria in both groups showed resistance to ampicillin, and sensitivity to aminoglycosides and ciprofloxacin .Conclusion : In diabetic patients, Escherichia coli was the most common organism isolated in CA while Klebsiella spp . was the commonest isolate in HA. In non-diabetics, Escherichia coli was the most common organism isolate from both CA and HA. Candida albicans was the commonest cause of candiduria in diabetic HA. Further, aminoglycosides and ciprofloxacin can be used empirically to treat both types of infection in diabetics and non-diabetics .
