What is black diphtheria?
The bacteria most commonly infect your nose and throat. The throat infection causes a gray to black, tough, fiber-like covering, which can block your airways. In some cases, diphtheria infects your skin first and causes skin lesions. Once you are infected, the bacteria make dangerous substances called toxins.
What are the 5 types of diphtheria?
Respiratory and cutaneous diphtheria are caused by toxic strains of the bacteria Corynebacterium diphtheriae and Corynebacterium ulcerans and very rarely Corynebacterium pseudotuberculosis….Diphtheria
- classical respiratory diphtheria.
- laryngeal diphtheria.
- nasal diphtheria and.
- cutaneous diphtheria (skin lesions).
What are the two types of diphtheria?
There are two types of diphtheria: respiratory and cutaneous. Respiratory diphtheria involves the nose, throat and tonsils, and cutaneous diphtheria involves the skin.
What does corynebacteria look like?
They are gram-positive, catalase-positive, non-spore-forming, non-motile, rod-shaped bacteria that are straight or slightly curved. Metachromatic granules are usually present representing stored phosphate regions. Their size falls between 2 and 6 μm in length and 0.5 μm in diameter.
Where is diphtheria most commonly found?
Since 2016, respiratory diphtheria outbreaks have occurred in Indonesia, Bangladesh, Myanmar, Vietnam, Venezuela, Haiti, South Africa, and Yemen. Cutaneous diphtheria is common in tropical countries.
Can diphtheria be cured?

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.
What is the pathophysiology of diphtheria?
Pathophysiology. Diphtheria is an acute infectious disease caused by the gram-positive bacillus Corynebacterium diphtheriae. It is characterized by a primary lesion, usually within the respiratory tract, and more generalized symptoms caused by release and spread of bacterial exotoxins throughout the body.
Where did diphtheria come from?
Diphtheria takes its name from the Greek word dipthera meaning leather and was named in 1826 by French physician Pierre Bretonneau. This is because it refers to the leathery, sheath-like membrane that grows on the tonsils, throat and in the nose.
