What is Diphtheria? Diphtheria is caused by the bacterium Corynebacterium diphtheriae. This germ produces a toxin that can harm or destroy human body tissues and organs. One type of diphtheria affects the throat and sometimes the tonsils. Another type, more common in the tropics, causes ulcers on the skin. Diphtheria affects people of all ages, but most often it strikes unimmunized children.
Diphtheria is an infectious disease caused by the Corynebacterium species of bacteria and is most often associated with a sore throat, fever, and the development of an adherent membrane on the tonsils and/or nasopharynx. Severe infections can affect other organ systems such as the heart and the nervous system. In addition, some patients with diphtheria can also have skin infections. Exotoxin produced by the bacteria is an important component in causing diphtheria's more severe symptoms. Medically Reviewed by a Doctor on 3/22/2016.
