A clinical study was conducted with the objective to isolate and identify the uterine aerobic bacteria in crossbred dairy cows with postpartum subclinical endometritis (SCE). One hundred and ninety four recently calved cows from different organized dairy farms in and around the city of Bangalore were screened for SCE by endometrial cytology using cytobrush technique on 35 day postpartum (dpp) from the cows. Uterine samples were collected from the cows found positive (98) for SCE using endometrial cytobrush for aerobic bacterial culture. Either single isolate (42.16 per cent) or mixed isolates (57.83 per cent) were isolated from the uterus in 83 out of 98 cows with SCE. The most common single isolate observed was Escherichia coli (45.71 per cent) in 16 out of 35 cows followed by Staphylococcus (42.86 per cent), Proteus spp. and Enterobacter sp. (5.71 per cent). Whereas, E. coli + Staphylococcus sp. were isolated as mixed isolates in 32 (66.67 per cent) out of 48 cows followed byE. Coli + Proteus in 11 cows, E. coli + Staphylococcus and E. coli + Enterobacter sp. in one cow each besides three cows (6.25 per cent) with more than three different isolates. In the present study, E. coli was the most frequently isolated aerobic bacteria either as single isolate or as mixed isolate with other aerobic bacteria in crossbred dairy cows at 35 dpp with SCE.
