erythrogenic toxin

Erythrogenic toxin is a harmful substance produced by certain bacteria, especially streptococcus groups responsible for illnesses like scarlet fever. This toxin causes the skin to develop a characteristic red rash and can lead to symptoms such as high fever and sore throat. It acts as a superantigen, triggering an excessive immune response that results in inflammation and the distinctive skin redness. The presence of this toxin is a key factor in the development of scarlet fever's symptoms, and its production highlights the importance of prompt treatment to prevent complications.
