**2.1.4** *Salmonella* **from bison**

Twenty bison from one herd in North Dakota, US were run through a chute and approximately 20 grams of feces obtained from the rectum of each animal. Fecal samples were transferred into sterile plastic cups, placed on ice and transported to the laboratory for culturing. *Salmonella* spp were cultured using the procedure described by Khaitsa et al (2007a). All suspect colonies were sent to National Veterinary Services Lab, Ames, IA for serotyping. Antimicrobial susceptibility testing was carried out using Sensititre Trek Diagnostic Systems, Westlake, OH.
