Necrotizing fasciitis: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

More than 80 types of the causative bacteria S. pyrogenes are in existence, making the epidemiology of GAS infections most complex. Wounds as minor as pinpricks, needle punctures, bruises, blisters, and abrasions or as serious as a traumatic injury or surgical incision can provide an opportunity for bacteria to enter the body.

In necrotizing fasciitis, group A beta-hemolytic Streptococcus and Staphylococcus aureus, working alone or together, are most commonly the primary infecting bacteria. They can enter the host via local tissue injury or through a breach in the integrity of a mucous membrane barrier. Other aerobic and anaerobic pathogens, including Bacteroides, Clostridium, Peptostreptococcus, Enterobacteriaceae, coliforms, Proteus, Pseudomonas, and Klebsiella, may be pres-ent. They can proliferate in an environment of tissue hypoxia caused by trauma, recent surgery, or medical compromise. The end product of this invasion is necrosis of the surrounding tissue, which accelerates the disease process by creating an even more favorable environment for the organisms.

Men are three times more likely to develop this rare condition than women, and the disease rarely occurs in children except in countries with poor hygienic practices. The mean age of the population contracting the disease is 38 to 44 years.
