This is a short list of diseases caused by bacteria. The reason the bacteria causes the disease varies with the bacteria. In tetanus the bacteria produces a nerve toxin that causes paralysis and eventual death. The bacteria is present in soil and infection is through an open wound. In tuberculosis it is not the bacteria but the body s defense mechanism in trying to kill the bacteria that kills the surrounding tissue where the bacteria resides which is the lung tissue.
Cholera is only a problem where sanitation is poor.
In botulism the bacteria produces an extremely deadly toxin.
