Corynebacterium diphtheriae & Diphtheria

Corynebacterium diphtheriae is a pathogenic bacterium that causes diphtheria. It is a Gram-positive nonmotile, club-shaped bacillus. Corynebacterium diphtheriae produces an extremely potent exotoxin known as diphtheria toxin which alters protein function in an infected individual. The toxin can be distributed by the circulatory system to other organs and may cause paralysis and congestive heart failure. Four subspecies of the bacteria are recognized: C. diphtheriae mitis, C. diphtheriae intermedius, C. diphtheriae gravis, and C. diphtheriae belfanti.
