Diphtheria - Wikipedi

  1. Diphtheria is an infection caused by the bacterium Corynebacterium diphtheriae. Most infections are asymptomatic or have a mild clinical course, but in some outbreaks more than 10% of those diagnosed with the disease may die. Signs and symptoms may vary from mild to severe and usually start two to five days after exposure. Symptoms often come on fairly gradually, beginning with a sore throat.
  2. Diphtheria (dif-THEER-e-uh) is a serious bacterial infection that usually affects the mucous membranes of your nose and throat. Diphtheria is extremely rare in the United States and other developed countries, thanks to widespread vaccination against the disease
  3. Diphtheria can be caused by one of several strains of bacteria called Corynebacterium diphtheria (C. diphtheria). Most infections of the respiratory tract and skin are caused by strains that release diphtheria toxin, which is then released in the body. Generally speaking, the more toxins that are released, the sicker a person with diphtheria.
  4. Diphtheria vaccination is recommended for all babies, children, teens, and adults. DTaP and DT are given to children younger than 7 years old, while Tdap and Td are given to older children and adults

  2. Diphtheria is a serious bacterial infection that affects the mucous membranes of the throat and nose. Although it spreads easily from one person to another, diphtheria can be prevented through the.
  3. Diphtheria Toxin is a bacterial exotoxin which consists of an active (A) domain, and a binding (B) domain. The toxin acts by binding to the HB-EGF receptor on cells and enters by receptor-mediated endocytosis. The acidic environment of the endosome causes the toxin to undergo a conformational change which causes part of the A domain to enter.
