MRSA Causing Necrotizing Fasciitis in 18-Month-Old Boy.
Necrotizing fasciitis is a rare and fulminant infection of the superficial fascia and subcutaneous cellular tissue. It is commonly polymicrobial, with the combination of aerobic and anaerobic bacteria, which contributes to the rapid progression and severity of the disease. The microbes commonly involved include group A streptococcus, Enterobacteriaceae, anaerobes, and Staphylococcus aureus. Over the past few years, skin and soft tissue infections, including necrotizing fasciitis, due to methicillin-resistant Staphylococcus aureus are increasing.
