An example of bacteria producing these toxins is Staphylococcus aureus. They are nonmotile, gram-positive, nonspore-forming, facultative anaerobic bacteria, which produce several enzymes and toxins. The enzymes include coagulase (both free and bound to cell membrane staphylokinase), hydraluronidase, phosphatase, proteinase, lipase, and gelatinase. The toxins produced by Staphylococcus aureus are aexotoxin (lethal, dermonecrotic, hemolytic, and leucolytic), b exotoxin (hemolytic), g exotoxin (hemolytic), d exotoxin (dermonecrotic and hemolytic), leucocidin (leucolytic), exfoliative toxin (causing the scalded skin syndrome in skin infections), and enterotoxins.
