The objectives of this study were to find out the bacteria from postpartum dairy cows, determination of their antimicrobial sensitivity, to diagnose subclinical endometritis via endometrial cytology and evaluation of reproductive performance. Uterine discharge from normally parturited cows (n=23) were examined for aerobic bacterial identification and antimicrobial sensitivity at a weekly interval. Isolates include gram-positive bacteria (n=13), gram-negative bacteria (n=10) and mixed bacteria (n=7). The most frequently found isolates of bacteria were as follow: E. coli (32.26%), Bacillus cereus (22.58%), Staphylococcus aureus (16.13%), Bacillus cereus + Staphylococcus aureus (9.68%) and Escherichia coli + Proteus vulgaris (3.23%). From all 13 antimicrobial agents used in the culture sensitivity test, Levofloxacin and Ciprofloxacin were highly sensitive antibiotics and metronidazole was found resistant against both gram-positive and gram- negative bacteria. Endometrial cytology was performed in 18 cows, out of which 6 cows were diagnosed with subclinical endometritis. Reproductive performance of these cows was assessed via evaluation of days to first artificial insemination, number of inseminations per conception and calving to conception interval. In conclusion, this study provided an update on information of bacteria present in uterus after parturition, their status of antibiotic resistance and further effect on reproductive performance of cows.
