The aim of this study was to investigate the prevalence, antibiotic susceptibility and genotypes of S. aureus of human, meat and poultry origin in Henan Province in China. A total of 327 beef, pork, chicken and human samples collected from local grocery stores and hospital were investigated. The prevalence of S. aureus was found to be 26.7% in beef, 37.5% in pork, 30.1% in chicken and 54.8% in human samples, respectively. Isolates were commonly found resistant to ampicillin (66.9%), tetracycline (61.4%), ciprofloxacin (67.5%) and gentamicin (77.1%), however, none of the isolates was resistant to rifampin and vancomycin, and only one strain of human origin was resistant to vancomycin. The multidrug resistance was common among 66.3% of the isolates. Multilocus sequence typing (MLST) analysis showed that two sequence types namely ST-239 and ST-5 were primarily prevalent among chicken and pork isolates while the most prevalent sequence types among beef and human samples were ST-9 and ST-398, respectively. ST-5 was identified among all isolates, suggesting that the source of S. aureus contamination among animal food and man has some relevance.
