Flashcards

What is a toxemic infection?

A toxemic infection is an infection where the toxin produced by the bacteria is the primary cause of the disease, rather than the bacteria itself.

Is relapsing fever a toxemic infection?

Relapsing fever is a bacterial infection that causes fever cycles, but the bacteria itself doesn't produce a toxin. The disease is caused by the bacteria multiplying in the blood.

Is tetanus a toxemic infection?

Tetanus infection is caused by a toxin released by the bacteria Clostridium tetani.

Is gas gangrene a toxemic infection?

Gas gangrene is a severe infection caused by toxins released by Clostridium perfringens. The toxins damage tissue and cause gas production.
