ABSTRACT
Yavari M, Haghkhah M, Ahmadi MR, Bacterial and antimicrobial evaluation of postpartum
endometritis in Holstein dairy cows. Onl J Vet Res., 11 (3): 14-23, 2007. Endometritis is an
inflammation of the endometrial lining of the uterus associated with delayed
uterine involution and poor reproductive performance. Bacteriological culture
from uterine swabs from Holstein dairy cows with postpartum endometritis and
antimicrobial susceptibility are reported. Eighty nine cows were swabbed 21 to
35 days postpartum from uterine lumens. Bacteria were identified by aerobic and
anaerobic culture. Disk diffusion was performed to determine susceptibility of
major pathogenic bacteria to antimicrobials. Most frequent were Arcanobacterium pyogenes, E. coli,
non-differentiated streptococci, staphylococci and bacilli. E. coli were sensitive to enrofloxacin and ceftiofur but
resistant to tetracycline and oxytetracycline. For A.
pyogenes, 72% were resistant to oxytetracycline,
66% to tetracycline and 72% to enrofloxacin and ceftiofur. All isolates were resistant to penicillin. The
results suggested that oxytetracycline may not be
effective for treatment of endometritis. We also found widespread bacterial
resistance to enrofloxacin and 3rd
generation cephalosporins.
