Main Factors of Staphylococcus aureus Associated with the Interaction to the Cells for Their Colonization and Persistence

Abstract

Staphylococcus aureus is a microorganism that can colonize the nose, pharynx, and other regions of the body. It has also been observed that it can cause persistence. Successful colonization of S. aureus depends in the factors that favor the interaction of the bacteria with host cells. The bacterial determinants of S. aureus that have the capacity to adhere to human tissues involve adhesion factors such as teichoic acids and cell-wall-anchored proteins (CWA) such as ClfA, IcaA, SdrC, FnBPA, among others. The colonization and persistence process first involve adhesion to the tissue, followed by its reproduction and the possible formation of a biofilm. This review will describe the main virulence factors that allow bacterial adhesion and biofilm formation, including the accessory gene regulator genes (agr), related to colonization and persistence of S. aureus.
