Staphylococcus aureus (S. aureus) has been shown to adhere, invade, and induce the death of various host cells. The prominent lineage of livestock-associated methicillin-resistant S. aureus (LA-MRSA) in Asia is the sequence type (ST) 9 that has emerged as a potential zoonotic pathogen. However, the virulence of LA-MRSA ST9 remains not clear. In this study, sixteen representative Taiwan LA-MRSA isolates were selected for adherence, invasion, and cytotoxicity studies against the human lung carcinoma epithelial cell line A549. The isolates showed 100% of cytotoxicity, 35.2% - 61% of adhesion, and 18% - 52.5% of invasion against A549 cells. Different adherent abilities …
