NECROTIZING FASCIITIS Necrotizing fasciitis is commonly known as , flesh eating bacteria (infection). Is a disease condition of rapidly spreading infection, usually located in fascial planes of connective tissue that results in tissue necrosis (dead and damaged tissue). The disease occurs infrequently, but it can occur in almost any area of the body. In many cases have been caused by Abeta-hemlytic streptococci (Streptococcus pyogenes), and many different bacterial genera and species, either alone or together (polimicrobial) can cause this disease.
Also in some cases mycotic (fungal) species causes necrotizing fasciitis. In the 1840 to 1870 this condition was described by several people and in 1952 Dr. B. Wilson termed the condition necrotizing fasciitis. Most likely the disease the disease had been happening many centuries before it was first described in the 1800s. As of now there names that have been used to clarify the same disease as necrotizing fasciitis: flesh –easting bacterial infection or disease , suppurative fasciitis, dermal Meleney , or Fournier’s gangrene and necrotizing cellulitis.
The word necrotizing placed before the body region , it locates the place in the body where it initially locates , for example necrotizing colitis and necrotizing arteriolitis but it all refer to the same disease. There are some cases reported that can be acquired just by a scrape of the skin on the beach . Also from dog and insect bites. The drug user would not know when it has enter the body, because it could be through the injection that could cause the infection that will present with a sign of simple cutaneous absecess.
Is very important in understanding that what ever the infection organism could be when it reaches and grows in the connective tissues and the of some organisms can progress about 3 centimeters per hour. Then the infection becomes difficult to stop with antimicrobial drugs and surgery . There are 3 general groups based on the genera of organisms causing the infection and some clinical findings that vary from patient to patient.
Type 1 is either caused by more than two bacterial genera (polymicrobial) or by the infrequently found single bacterial genus such as Vibro or fungal genera such as Candida. Type 2 is caused by Streptococcus spp, and Type 3 (or termed type 3 gas gangrene) is caused by Clostridium spp. Most cases of necrotizing fasciitis are caused by bacteria, is very rare that other organism such as fungi cause this disease.
