How can one bacterium, C. perfringens cause three different diseases including cellulitis, gas gangrene and food poisoning?

maybe it depends on what part of the body it infects and what cells do it's toxins reach?

Huh? I found at least 41 starins in the ATCC, and considering what a starin is in bacteriology, there are probably thousands if ou consider all the isolates that have been established in the different labs around the world.

No, I would back up Mr Mistery o this one. Different infection sites, different reactions of the body, different illnesses.

C. Perfringens may produce different toxins. For example, food intoxication may occur with enterotoxigenic strains of perfringens. Other toxins are responsible of gas gangrene, while site of infection, and host susceptibility are (of course) very important to determine the disease.
