Urinary Tract Infections (UTIs) are the common and topmost nosocomial infection, posing threat for both the patients and associated personnel in hospital. The study was conducted to determine the prevalence of bacteria in urine samples and the antibiotic sensitivity pattern of the clinical isolates of UTI causing uropathogens. A cross-sectional study was carried out on 186 patients admitted to Chattagram Maa-O-Shishu Hospital from November, 2017 to April, 2018. The mid-stream urine specimens were collected from the patients through aseptic way and then cultured on McConkey, Blood and HiChrome UTI media. The specimens that showed ≥105 cfu/ml were regarded as positive for the bacterial infection and antimicrobial susceptibility tests (Kirby-Bauer disk diffusion method) were performed on those isolates. Among the 91 culture-confirmed positive UTIs (29.6 % male and 60.9% female), 21 and 70 UTIs were due to the gram positive and gram-negative bacteria, respectively. The main responsible pathogens were Escherichia coli (51.6%), K. pneumoniae (22%), S. aureus (13.2%), P. mirabilis (5.5%), Enterococcus spp. (4.4%) and P. aeruginosa (3.3%). It is suggested that four factors include awareness on UTI, recognition causative factors, prevention and treatment should be emphasized highly for ensuring safe public health.
