Molecular epidemiologic investigation of Campylobacter coli in swine production systems, using multilocus sequence typing

Multilocus sequence typing of 151 Campylobacter coli isolates from swine reared in conventional (n = 74) and antimicrobial-free (n = 77) production systems revealed high genotypic diversity. Sequence type (ST) 1413 was predominant and observed among ciprofloxacin-resistant strains. We identified a C. coli ST 828 clonal complex consisting of isolates from both production systems.
