This study aimed to determine the bacterial isolates associated with postpartum endometritis among dairy cows in Western Australia and their antimicrobial susceptibility profiles. A cross-sectional was conducted between June-October 2020. Endometritis defined as evidence of mucopurulent purulent vaginal discharge 60-100 days postpartum. Vaginal samples were obtained, cultured, identified tested for susceptibility. total 118 grown from 46 animals, representing 36 species. The bacteria isolated both aerobic anaerobic cultures included Bacillus (60.2%), Streptococcus (12.7%), Trueperella (10.1%), Escherichia (6.7%) Staphylococcus (5.9%). remaining genera <5% Histophilus, Aeroccocus, Enterococcus Moraxella. Resistance variable isolates, but highest resistance levels observed Streptococcal enrofloxacin, clindamycin erythromycin, respectively. All exhibited 100% greatest found luteinises trimethoprim-sulfamethoxazole 83%, 66% 33% quinupristin-dalfopristin. There 84.5% 35.2% erythromycin licheniformis subtilis. coli 12.5% gentamycin, ceftiofur, whereas amoxicillin-clavulanic acid 37.5%. Within Staphylococcal 28.5%, 42.8% 14.2% cefoxitin, penicillin tetracycline observed, presence important antimicrobials human use, such cephalosporins, macrolides fluoroquinolones, highlights need judicious use cattle.
