What is the pathogen of erysipelas?

The pathogen of erysipelas is beta hemolytic streptococci.

Beta hemolytic streptococci is a common bacterium with strong invasiveness. This bacterium can secrete a variety of enzymes and toxins, which can help it break through the body's defense mechanisms and enter the skin and subcutaneous tissue to cause infection. The enzymes produced can decompose some components in the tissue and create conditions for the spread of bacteria. Secondly, beta hemolytic streptococci can adhere to the epithelial cells of the skin and other surfaces, thus better colonization and infection. once attached successfully, it can multiply rapidly and trigger an inflammatory reaction.

Moreover, the bacterium is highly virulent and can cause a strong immune response, resulting in typical symptoms such as redness and heat pain. In addition, when the body's resistance is reduced, such as skin damage, local blood circulation disorders, or some underlying diseases, it is more likely to take advantage of the weakness to cause erysipelas. Moreover, it may also spread through contact transmission, increasing the risk of infection.
