Sažetak
Streptococcus agalactiae is one of the uropathogens responsible for urinary tract infections (UTI ) in children, pregnant women, and elderly people with chronic underlying diseases. This study was performed to determine the prevalence of urinary tract isolates of group B streptococci (GBS) in a group of females referred to a referral University Hospital in Iran. In this retrospective cross-sectional study, urine analysis and urine culture results of all female subjects referred to the laboratory of the Rasoul-e-Akram Hospital, Tehran, Iran in 2010 were reviewed. Bacteriuria, colony count, pyuria and demographic data of patients were also evaluated. In this study, 10,256 females were investigated; 2061 (20.1%) of them had positive urine cultures. GBS was the isolated microorganism in 184 (8.92%) cases, yielding a prevalence of 1.79% in total study population. The mean age of subjects with positive GBS cultures was 48.24}18.8 years, with a higher prevalence recorded in the 51-60 and 21-30 age groups. The highest rates of cultures positive for GBS were seen in December and January. GBS was found to be sensitive to the following antibiotics: cephalothin (100%), norfloxacin (96.9%), ampicillin (96%), nitrofurantoin (95.5%), and vancomycin (95%). In this study, GBS showed greatest resistance to tetracycline (81.6%) and co-trimoxazole (68.9%). In conclusion, the prevalence of GBS in females with suspected UTI is relatively low; however, attention to the age and susceptibility pattern of antibiotic treatment for UTI caused by this microorganism is necessary.
