Study of bacteria isolated from urinary tract infection and their sensitivity pattern.

A retrospective study was conducted among out-patient and in-patient in Kathmandu medical college Teaching hospital of one month from the duration 2060-11-15 to 2060-12 -15. Mid-stream urine [MSU] of 300 patient were cultured. Out of these 75 patients urine were found to have significant bacterial growth. Total of five species of bacterial species isolated were viz.E.coli 37 (33.3%) Proteus species 25 (27.7%) Klebsiella species 15 (16.6%) Staphylococcus aureus 8 (8.8%) and Pseudomonas aureginosa 1 (1.1%). Regarding their antibiotic sensitivity pattern E. coli were sensitive to Nitrofurantoin 31 (83.8% ) Norfloxacin 25 (67.5%) Ofloxacin 30 (81.0%) Amoxycillin 16 (43.2%) Nalidixic acid 15 (40.5%).proteus species were sensitive to Nitrofurantoin 15 (60.0%) Norfloxacin 15 (60.0%) Ofloxacin 12(48.0%) Amoxycillin 13(52.0%) Nalidixic acid 10 (40.0%) Ciprofloxacillin 12 (48.0%). Klebsiella species were sensitive to Nitrofurantoin 9 (60.0%) Norfloxacin 5 (33.3%) Oflaxin 6 (40.0%) Amoxycillin 5 (33.3%) Nalidixic acid 4 (26.6%) ciprofloxacillin 6 (40.0%). Staphylloccus aureus were sensitive to Nitrofurantoin 8 (100.0%) Norfloxacin 6 (75.0%) Oflaxin 8 (100.0%) Amoxycillin 7 (87.5%) Nalidixic acid 6(75.0%) Ciprofloxacillin 8 (100%). And Pseudomonas aureginosa were resistant to all antibiotics which we are using in this research work. (authors)
