Antibiotic sensitivity of isolates was carried out against commercially available antibiotics using the disc diffusion method on Mueller-Hinton Agar. The incidence of E. coli was found to be higher in females than in males, as out of 200 urine samples, 132 were females and 68 were males. With regards to age-wise distribution, this study revealed that among the females the incidence was reported in all age categories with the highest being in the post-menopausal and the infant age groups, while for males the incidence was high in the older age group (above 50 years). The prevalence of E. coli was more in out - patients (OPD) than the in- patients (IPD) as there were 141 OPD samples and 95 IPD samples, thereby indicating that this infection also has a community-based source of transmission. E. coli isolates were reported to be the most sensitive to imipenum and tazobactam, while the greatest resistance of these isolates was against ampicillin and trimethoprim sulfamethoxazole.]]>Guentzel, M.N.,1991Escherichia, Klebsiella, Enterobacter, Serratia, Citrobacter and Proteus.]]>1991pp: 377-388pp: 377-388Gupta, K., D.
