Necrotizing fasciitis types

The main types of necrotising fasciitis are: Type I (polymicrobial ie, more than one bacteria involved) Type II (due to haemolytic group A streptococcus, and/or staphylococci including methicillin-resistant strains/MRSA) Type III (gas gangrene eg, due to clostridium There are many types of bacteria that can cause the flesh-eating disease called necrotizing fasciitis. Public health experts believe group A Streptococcus (group A strep) are the most common cause of necrotizing fasciitis. This web page only focuses on necrotizing fasciitis caused by group A strep bacteria Necrotizing fasciitis (NF), a life-threatening rare infection of the soft tissues, is a medical and surgical emergency. It is characterized by subtle, rapid onset of spreading inflammation and necrosis starting from the fascia, muscles, and subcutaneous fat, with subsequent necrosis of the overlying skin Necrotizing fasciitis (NF), also known as flesh-eating disease, is an infection that results in the death of parts of the body's soft tissue.

The most commonly affected areas are the limbs and perineum

The most rapidly progressing type of necrotizing fasciitis is Group A streptococcal infection, also known as flesh-eating bacteria. Necrotizing fasciits can also involve microbial infections with a singular bacteria (monomicrobial) or a combination of bacteria (polymicrobial) The presence of anaerobes (or facultative anaerobes) in type I infection is responsible for the hallmark finding of gas formation found later in the course of polymicrobial necrotizing fasciitis. However, the finding is not present in monomicrobial necrotizing fasciitis due to group A streptococci Necrotizing fasciitis is a subset of the aggressive skin and soft tissue infections (SSTIs) that cause necrosis of the muscle fascia and subcutaneous tissues. This infection typically travels along the fascial plane, which has a poor blood supply, leaving the overlying tissues initially unaffected, potentially delaying diagnosis and surgical intervention Group A beta-hemolytic streptococci have historically been noted as a cause of necrotizing fasciitis, but Haemophilus aphrophilus and S aureus are also associated with the condition, and some..
