Prevalence and susceptibility pattern of Urinary Pathogens.

Urine specimens from 3125 cases were received in the laboratory, on which culture and sensitivity tests were performed. Only 24.8% of cases with significant bacterial growth (100,000 organisms per ml) were tested for their susceptibility to various antibiotics. The organisms were identified by conventional methodology. The susceptibility to antibiotics was determined by disc diffusion technique. Escherichia coli was the commonest (50.97%) of all the isolates to cause UTI, followed by Klebsiella spp (16%) and Pseudomonas aeruginosa (9.03%). 93.0% of E. coli were susceptible to Ofloxacin, 90.12% to Norfloxacin, 89.11 % to Ceftriaxone, 84.05% to Nitrofurantion, 82.02% to Gentamicin, 77.21% to Cephradine, 75.94% to Pipemidic acid, 31.89% to Cotrimoxazole and 29.87% to Ampicillin. Out of Pseudomonas, 97.14% were susceptible to Amikacin, 82.85% to Aztreonam, 51.42% to Ofloxacin, 48.57% to Pipemidic acid, 47.14% to Norfloxacin, 32.85% to Tobramycin and 31.42% to Gentamicin. E. coli was highly sensitive to Ofloxacin and Norfloxacin but highly resistant to Ampicillin and Cotrimoxazole.
