Background: Asymptomatic bacteriuria (ASS) is common among women with diabetes. The aim of this study was determine the prevalence of and risk factors for ASB in women with diabetes type 2 in Shahre-kord city of Iran. Methods: In a six months period (April- September 2005), a total of 100 women with diabetes (type 2) and 100 healthy women without diabetes as control group were investigated for the presence of ASH. After a follow-up of six months, the rate of developing ofASB to symptomatic urinary tract infection (UTI) in patients was evaluated. Results: The prevalence of ASB was 20% in the diabetic patients and 40/0 in control group (P< 0.05). Escherichia coli, Coagulase negative staphylococci, Enterococcus spp. and Klebsiella pneumoniae were the most prevalent isolates respectively. Pyuria was present in 80% of patients withASB and in 17.5% of those without ASB. Symptomatic UTI in previous year was the only risk factor for ASH in the patients (P< 0.05). During a follow-up of six months, 40% of diabetic patients with ASB developed to symptomatic UTI. Conclusions: The prevalence of ASB is increased in women with diabetes and we recommend screening for detection and treatment of ASB in diabetic patients.
