Impact of extracellular enzymes on Staphylococcus aureus host tissue adaptation and infection.

Abstract

Staphylococcus aureus is a multi-host pathogen that can colonize and infect both humans and livestock in a tissue-specific manner. This amazing feature of the pathogen is mainly facilitated by the surplus virulence agents produced upon necessity and favorable environmental factors. These factors are adept at damaging cellular barriers, manipulating host immune factors, and circumventing the host complement system. The delicate balance between the timely release of virulent factors and the regulation of their production underscores the significance of the exoenzyme network. Moreover, the intricate relationship between the pathogen and host tissue highlights the importance of understanding tissue-specific phenotypes for effective therapeutic strategies. Here, we provide a review on the diverse role played by the extracellular enzymes of S. aureus in tissue-specific infection and systemic colonization leading to distinctive diseased conditions. The article highlights the need to study the role of staphylococcal exoenzymes in various systemic invasions, their impact on the deterioration of host tissue, and the regulation of S. aureus virulence factors.
