LCT and Cutaneous abscess: Notably, phenotypic tests (e.g. haemolysin activity and α-toxin quantitation) and mouse skin abscess model demonstrated that MR526 had similar virulence as the prototype USA300-LAC strains, suggesting the China ST8 USA300-like strains (e.g. MR526) did not attenuate virulence after the introduction into a new geographical region.
