Background: Bacteria are capable of invading and infecting humans, leading to disease and sometimes death. Systems and tissues in human body are vulnerable to different organisms. Infection pattern is likely to differ by geographical regions. Aim: This study was aimed to isolate and identify the type of aerobic bacteria causing Urinary Tract Infections (UTI) in different age groups and sexes, and also in some predisposing conditions. Their antibiogram also was done. Materials and Methods: Midstream urine sample collected aseptically from 276 patients were subjected for isolation and identification of aerobic bacteria by standard technique and subsequently antibiogram was done by Kirby –Bayer Method. Both sexes of patients with an age range of 10-70 years and patients with diabetes (22), hypertension (8) and anemia (8) were also included in the study. Results: Escherichia coli was the predominant organism(50%) among other isolates – Klebsiella species (27.3%), Proteus species(7.14%), Staphylococcus saprophyticus (5.95%), Staphylococcus aureus (3.57%), Enterococci (3.57%), Pseudomonas species(2.38%). UTI was more common among patients of 60 and more years of age; however, incidence was more in female patients (36.2 – 38.5%) compared with male patients (25-30%). Anemia, Diabetes and Hypertension conditions were found to predispose UTI. Aminoglycosides and Quinolones were found to be more effective against the isolates. Conclusion: The present study reveals in spite of the topographical diversity, the infecting bacterial isolates from this area were found to be the same as from any other part of India.
