To expand a bit, auto-immune diseases result when an animal's or human's immune response perceive something normal in the body as foreign and try to destroy it. It's not caused by a bacteria or virus, although secondary infections can occur as the organ under attack breaks down. In the case of pemphigus, the over-reactive immune response produces antibodies that attack the "cement" that holds the cells together and causes them to separate.
