How is gelatinase a virulence factor
Web1 dec. 2006 · Results demonstrated that the virulence factor gelatinase is disseminated among the genus Enterococcus and that dairy isolates are capable of producing gelatinase at comparable levels with clinical isolates, although this capacity is easily lost during conservation by freezing in the laboratory. Webence and activity of virulence factors were significantly different between the species. Only VRE isolates were selected to compare virulence characteristics between E. faecalis and E. faecium. E. faecalis carried gelE at a significantly higher fre-quency and presented gelatinase activity more frequent-ly than E. faecium (p < 0.001).

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.

As discussed in the previous section, the first two steps in pathogenesis are exposure and adhesion. Recall that an adhesin is a structure, such as a protein or glycoprotein, found on the surface of a pathogen that attaches to receptors on the host cell.
