Although the lytic activity of some microbe-derived hemolysins on red blood cells may be of great importance for nutrient acquisition, many hemolysins produced by pathogens do not … See more Many bacteria produce hemolysins that can be detected in the laboratory. It is now believed that many clinically relevant fungi also produce hemolysins. Hemolysins can be identified by their ability to lyse red blood cells in vitro. See more The structure of several hemolysins has been solved by X-ray crystallography in the soluble and pore-forming conformations. For example, α-hemolysin of Staphylococcus aureus forms a homo-heptameric β-barrel in biological membranes. The See more As hemolysins are produced by pathogenic organisms, the main treatment is the intake of antibiotics specific to the pathogen that have caused the infection. Moreover, some hemolysins may be neutralized by the action of anti-hemolysin antibodies, … See more • Hemolysis (microbiology) • Pore-forming toxins • Staphylococcus aureus See more One way hemolysin lyses erythrocytes is by forming pores in phospholipid bilayers.
