Streptococcal necrosis

Streptococcal necrosis is an acute purulent disease caused by beta; -hemolytic streptococcus infection, and is mainly characterized by skin sheet necrosis, so it is also called acute streptococcal skin necrosis. beta; -hemolytic streptococcus is highly pathogenic, and it can produce hemolysin in the culture medium, so that a broad and transparent hemolytic ring appears around the colony. Invasion of the human body can quickly destroy local tissues and spread around. Entry into the blood can cause a hemolytic response. From the beginning of the disease, the main manifestations of local skin are redness, swelling, and pain, which is very similar to erysipelas, and also known as necrotizing erysipelas and hospital necrosis. It can occur after extremity trauma, and there is no obvious history of trauma. After the advent of penicillin, the disease is rare.
