Abstract

Staphylococcus aureus, konakçılarında kolonize olabilmek ve hastalık oluşturabilmek için çok çeşitli ekzotoksinlere sahiptir.
Bu ekzotoksinlerin esas görevi konakçı dokularını, bakterinin gelişmesine uygun hale getirmektir. Bu derlemede, S aureus tarafından
salgılanan ekzotoksinlerin ve hemolizinlerin yapılarından ve biyolojik fonksiyonlarından bahsedilmiştir.

Exotoxins of Staphylococcus Aureus

Abstract

Staphylococcus aureus has a wide variety of exoproteins that contribute to its ability to colonize and cause disease in
its hosts. The main function of these proteins are to convert local tissues into suitable condition for bacterial development. This review
addresses the structure and biological functions of the exotoxins and hemolysins secreted by S.aureus.
