RESUMO
@#Staphylococcus aureusis a major cause of hospital and community acquired infection,which can express many kinds of cell wall-related and extracellular virulence factors,causing a variety of infectious diseases. Ebh protein is involved in the adhesion,aggregation and biofilm formation of Staphylococcus aureus,and thus closely related to its strong pathogenicity. The pathogenesis of Staphylococcus aureus is controlled collaboratively by different two-component signal transduction systems and transcriptional regulation factors,among which ArlRS is the key two-component system(TCS)necessary for the adhesion,biofilm formation and virulence. At the same time,ArlRS regulates Ebh protein through global regulation factor MgrA,thus affecting the role of Staphylococcus aureus in human infectious diseases. In this paper,the regulatory mechanism was reviewed.
