Clostridium perfringens
A family of highly conserved cholesterol-dependent cytolysins, closely related to perfringolysin from "Clostridium perfringens" are produced by bacteria from across the order Bacillales and include anthrolysin, alveolysin and sphaericolysin. Sphaericolysin has been shown to exhibit toxicity to a limited range of insects injected with the purified protein.
