Interactions between bacterial virulence and antimicrobial resistance are of increasing interest in clinical microbiology. On this account, antimicrobial resistance of Y. enterocolitica O:3 strains isolated from humans (n = 55), food chain animals (n = 58) and companion animals (n = 13) was determined in relation to the absence or presence of the pYV plasmid-encoded virulence genes yadA and virF. There were no statistically significant associations between the rate of antimicrobial resistance and the presence or absence of the plasmid, either in human- or animal-derived strains. Therefore, it can be concluded that response to conventionally used antimicrobials in Y. enterocolitica O:3 strains is not dependent on pYV -encoded virulence determinants.
