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.
