Abstract

The objective of this study was to determine the occurrence of Campylobacter , Salmonella and Escherichia coli O157:H7 in fecal samples from a herd of bison and determine antimicrobial susceptibility patterns of pathogens isolated. Fecal grabs were obtained from the rectum of each bison ( n =20). None of the fecal samples tested positive for E. coli O157:H7 or Campylobacter spp. Two of 20 (10%) bison fecal samples tested positive for Salmonella spp. The Salmonella isolates belonged to the serotypes Salmonella Typhimurium (Copenhagen) and Salmonella Worthington. Both isolates were resistant to the same 13 of 20 antimicrobials tested, including macrolides (erythromycin, tilmicosin, tylosin), tetracyclines (chlortetracycline, oxytetracycline), florfenicol, most sulfonamides and penicillin. S. Worthington was also resistant to ampicillin. They were susceptible to at least six antimicrobials including ceftiofur, enrofloxacin and some aminoglycosides.
