A Urinary Tract Infection (UTI) is a bacterial infection that affects any part of the urinary tract. It is second most common type of infection in the body and serious health problem affecting millions of people each year. Women are especially prone to UTI?s than men. According to epidemiological data, 35-45% of all acquired infections occur in the urinary tract and 80% are associated with bladder. Individual susceptibility to infection is shown by an abnormal colonization of microorganisms at periurethral region. Uroepithelial cells have greater ability to bind infectious microbes by surface adherence. We evaluated totally 1105 cases with symptoms and sign of UTI were enrolled for the study. We analyzed a database comprising 1105 patients. A mid-stream urine samples were collected from symptomatic out-patients and in-patients from different age groups (less than 15 years, 15-40 years, above 40 years) of both sex. The percentage of urine sample showing significant bacteriuria and to find out: different bacterial flora associated with UTI; most predominant and common bacterial flora associated with UTI was found out. In our study among the total patients only 357 cases were culture positive. The organisms responsible to cause UTI was E.coli (80%), other organism were Staph aureus (7%), Klebsiella (4%), Enterococci (3%), Pseudomonas aeruginosa (3%), Enterobacter (2%) and Proteus vulgaris (1%). The investigation also showed that most predominant organism isolated was E.coli . The highest rate of UTI cases were females compared to males.
