The virulence of enterococci is known to be conferred by various factors including but not limited to cytolysin (CylLLLSM), Enterococcal surface protein (Esp), aggregation substance (AS), gelatinase (GelE), E.
All these potential mechanisms of activation, recognition, and elimination of target cells by NK cells, alone or in combination, induce the release of the content of their lytic granules (perforin, granzyme, and cytolysin).
Listeria monocytogenes can activate all three branches of the UPR and downstream apoptotic signaling via secretion of cytolysin listeriolysin O (LLO), likely by disturbing ER calcium homeostasis through its pore-forming activity [121, 122].

faecium isolates are characterized by a high frequency of genes encoding putative virulence factors, such as collagen adhesin (acm gene), enterococcal surface protein (esp gene), hyaluronidase (hyl gene), gelatinase (gelE gene), endocarditis antigen (efa gene), and cytolysin (cyl operon) [6].

Some of the most important virulence factors include the production of hydrolytic enzymes, namely, gelatinase, lipase, and DNase, haemolytic activity and the production of cytolysin, the presence of adhesins, and the ability to form biofilms [127].
