Genotypes and Antibiotic Resistances of Campylobacter jejuni and Campylobacter coli Isolates from Domestic and Travel-Associated Human Cases Lilian Niederer a , Peter Kuhnert a , Ralph Egger a , Sabina Büttner b , Herbert Hächler c and Bożena M. Korczak a a Institute of Veterinary Bacteriology, Vetsuisse Faculty, University of Bern, Bern, Switzerland b Swiss Federal Veterinary Office, Bern, Switzerland c Swiss National Centre for Enteropathogenic Bacteria (NENT), Institute for Food Safety and Hygiene, University of Zurich, Zurich, Switzerland ABSTRACT Multilocus sequence typing (MLST) extended with flaB typing of 425 Campylobacter jejuni isolates and 42 Campylobacter coli isolates revealed quite a low overlap between human isolates from travel-associated and domestic cases in Switzerland. Men were more frequently affected by Campylobacter than women, but strains from women and, overall, from travel-associated cases showed mutations conferring quinolone resistance more frequently than strains from men and domestic cases, respectively.
