Diphtheria is caused by the bacterium Corynebacterium diphtheriae, a gram-positive bacillus. There are three biotypes of the bacterium (gravis, mitis, and intermedius) capable of producing diphtheria, though each biotype varies in the severity of disease it produces.he Corynebacterium diphtheriae bacterium causes disease by invading the tissues lining the throat and producing diphtheria toxin, a substance which destroys the tissue and leads to the development of the adherent pseudomembrane characteristic of respiratory diphtheria.
