streptolizinok
Streptolysin O is a potent exotoxin produced by certain strains of Streptococcus pyogenes, a bacterium also known as group A Streptococcus. This toxin is a key virulence factor, contributing significantly to the pathogenesis of streptococcal infections. It belongs to the thiol-activated cytolysin family, meaning its activity is dependent on the presence of reducing agents and it can be inhibited by cholesterol.
The primary action of streptolysin O is to form pores in the cell membranes of eukaryotic cells,
Due to its ability to lyse red blood cells, streptolysin O is a hemolysin. Its detection in
