Diphtheria is caused by strains of Corynebacterium diphtheriae infected with a prophage that carries an exotoxin producing gene. This exotoxin spreads throughout the body, damaging multiple organ systems by interfering with cellular protein synthesis. A pseudomembrane composed of Corynebacterium diphtheriae can block the airway and cause suffocation. Diphtheria can be prevented with DTP (diphtheria, tetanus, and pertussis) vaccine and treated with both antitoxin and antibiotics.
