Turbid uterine discharges from 238 endometritic cows at estrus, that had failed to conceive despite repeated inseminations, were collected for aerobic bacterial isolations and identification. The isolates were then tested for their sensitivity to various chemotherapeutic agents. Out of 238 uterine discharge samples, bacterial isolates were recorded in 147 (61.76%), while 91 (38.24%) were bereft of bacteria. Out of 147 isolates, 124 (84.4%) were recorded as pure cultures and 23 (15.6%) as mixed infections. Gentamicin and ciprofloxacin were equally efficacious with highest percentage sensitivity recorded as 91.8% each. The % sensitivity to other antibiotics in descending order was: enrofloxacin (83.6), tetracycline (76.8), amoxicillin (70.7), cloxacillin (66.6), streptomycin (55.1) and penicillin (53.7).
