ABSTRACT
Campylobacter is a major foodborne pathogen that causes outbreaks and sporadic gastrointestinal disease, creating a serious disease burden. Campylobacter strains isolated from diarrhea cases (n = 11) and raw poultry meat products (n = 2) in Huzhou, including 11 Campylobacter jejuni and 2 Campylobacter coli strains, were subjected to virulence gene, drug resistance gene, genetic correlation, antibiotic resistance, and multilocus sequence typing (MLST) analyses. The 13 Campylobacter isolates were divided into 12 sequence types (STs), one of which was a new ST. The isolated strains contain multiple virulence-related genes. Drug sensitivity analysis showed that the resistance rate of the 13 isolates to nalidixic acid, ciprofloxacin, and tetracycline was 92.3%. Genome sequencing indicated that all 11 strains of C. jejuni carried the tet(O) and blaOXA resistance genes, and 2 strains of C. coli carried multiple drug resistance genes. Phylogenetic analysis based on core-genome single-nucleotide polymorphisms indicated that the 11 C. jejuni isolates from diarrhea patients and food sources are not closely phylogenetically related.
