How is gelatinase a virulence factor

WebGelatinase is one of the virulence factors in E. faecalis. The production of gelatinase is active only in late-log to early-stationary phase. Addition of conditioned medium shifts the onset of the production to mid-log phase, suggesting the presence of an induction factor.
