This study was undertaken to determine the prevalence, antimicrobial susceptibility, and genetic relatedness of Salmonella enterica subsp. enterica and Campylobacter spp. in poultry meat, and to analyze the association of genetic types of these bacteria with their geographical distribution and antimicrobial resistance profiles. Fifty-four and 71 of 100 samples were found to be contaminated with Salmonella and Campylobacter, respectively. Nine Salmonella serotypes were found, including S. enterica subsp. enterica serovar Infantis (33%), Schwarzengrund (12%), Manhattan (9%), and others. Campylobacter jejuni and C. coli were detected from 64 (64%) and 14 (14%) samples, respectively. S. enterica subsp. enterica exhibited a high frequency of resistance against tetracycline (78.3%) and streptomycin (68.3%). C. jejuni and C. coli isolates were resistant to sulfamethoxazole/trimethoprim (90.5%), nalidixic acid (47.3%), ampicillin (45.9%), and ciprofloxacin (40.5%). Cluster analysis was performed for the Salmonella isolates using PFGE and for the Campylobacter isolates with PFGE as well as comparative genomic fingerprinting. which were combined with the drug-resistance data to analyze with respect to the locations in which the poultry meat was produced. This analysis revealed that C. jejuni strains with a particular genotype and antimicrobial resistance profile are spreading in specific areas in Japan.
