Abstract
This study was to investigate the prevalence and characteristics of
antimicrobial-resistant Staphylococcus aureus and
methicillin-resistant S. aureus (MRSA) from 4,264 retail meat
samples including beef, pork, and chicken in Korea between 2013 and 2018. A
broth microdilution antimicrobial susceptibility testing was performed for
S. aureus. Molecular typing by multilocus sequence typing
(MLST), spa typing, and pulsed-field gel electrophoresis
(PFGE), was performed on mecA-positive S.
aureus strain. S. aureus was isolated at a rate of
18.2% (777/4,264), of which MRSA comprised 0.7% (29 strains). MLST
analysis showed that 11 out of the 29 MRSA isolates were predominantly sequence
type (ST) 398 (37.9%). In addition, ST72, ST692, ST188, ST9, and ST630
were identified in the MRSA isolates. The spa typing results
were classified into 11 types and showed a high correlation with MLST. The
antimicrobial resistance assays revealed that MRSA showed 100% resistance
to cefoxitin and penicillin. In addition, resistance to tetracycline
(62.1%), clindamycin (55.2%), and erythromycin (55.2%) was
relatively high; 27 of the 29 MRSA isolates exhibited multidrug resistance. PFGE
analysis of the 18 strains excluding the 11 ST398 strains exhibited a maximum of
100% homology and a minimum of 64.0% homology. Among these, three
pairs of isolates showed 100% homology in PFGE; these results were
consistent with the MLST and spa typing results. Identification
of MRSA at the final consumption stage has potential risks, suggesting that
continuous monitoring of retail meat products is required.
