Strain HCM3A showed all the characteristics of a CA-MRSA strain with low level oxacillin resistance that can easily be missed on testing, susceptibility to most other agents tested, and the presence of SCCmec type V. It contained several virulence factors that are associated with severe infections caused by S. aureus, including PV-luk and seb, on MGE [32], [33]. Here, SETBP1 is linked to infection.
