in bovine endometritis, Onl J Vet Res., 29 (11): 674-694,
2025. Endometritis induces delayed uterine
involution and poor reproductive performance. We report bacterial culture uterine
swabs and antibiotic susceptibility from 89 dairy cows by 21-35 day postpartum
endometritis. Swabs were collected from the uterine lumen and bacteria identified
by aerobic and anaerobic culture. Antibiotic susceptibility of pathogenic
isolated bacteria was determined by disk diffusion yielding Arcanobacterium
pyogenes, E. coli, and non-differentiated streptococci,
staphylococci and bacillus spp. E. coli was sensitive to enrofloxacin and ceftiofur but
resistant to tetracycline and oxytetracycline. A. pyogenes, were resistant to oxytetracycline
72, tetracycline 66, enrofloxacin and ceftiofur 72%. We found widespread resistance to enrofloxacin and third generation cephalosporins.
