At least 3e5 presumptive Campylobacter spp. colonies were picked and underwent Gram staining, catalase and oxidase test. All suspect strainswere identified to the species level using the API Campy identification system (Biomerieux). Campylobacter isolates were subjected to antimicrobial susceptibility tests by the disc diffusion method as recommended by the National Committee for Clinical Laboratory Standards (NCCLS, 2003)
