Can diphtheria mutate?

Can diphtheria mutate?

ulcerans diphtheria toxin gene is of note because accumulation of these gene mutations potentially could lead to decreased effectiveness of the diphtheria toxoid vaccine for prevention and diphtheria antitoxin for treatment of toxigenic C. ulcerans disease.

What genetic element is responsible for the ability of Corynebacterium diphtheriae to make diphtheria toxin?

Two factors have great influence on the ability of Corynebacterium diphtheriae to produce the diphtheria toxin: (1) low extracellular concentrations of iron and (2) the presence of a lysogenic prophage in the bacterial chromosome.

Where is the gene for diphtheria toxin production?

Diphtheria toxin (DT) is an extracellular protein of Corynebacterium diphtheriae that inhibits protein synthesis and kills susceptible cells. The gene that encodes DT (tox) is present in some corynephages, and DT is only produced by C. diphtheriae isolates that harbor tox+ phages.

What toxin does diphtheria produce?

Diphtheria toxin is an exotoxin secreted by Corynebacterium, the pathogenic bacterium that causes diphtheria. The toxin gene is encoded by a prophage called corynephage β….Diphtheria toxin.

Can diphtheria be cured?

Today, the disease is not only treatable but also preventable with a vaccine. The diphtheria vaccine is usually combined with vaccines for tetanus and whooping cough (pertussis).

What is the prevention of diphtheria?

Vaccination. Keeping up to date with recommended vaccines is the best way to prevent diphtheria. In the United States, there are four vaccines used to prevent diphtheria: DTaP, Tdap, DT, and Td. Each of these vaccines prevents diphtheria and tetanus; DTaP and Tdap also help prevent pertussis (whooping cough).

What is the main cause of diphtheria?

Diphtheria is a serious infection caused by strains of bacteria called Corynebacterium diphtheriae that make a toxin (poison).
