Historically, anaerobic pedal infections have not been referenced as extensively in the literature as their counterparts in the brain, mouth, breast, pelvis, ear, liver, lungs and intestinal tract. This may be due to the numerous confusing colloquial terms often ascribed to them. Terms such as "hospital gangrene", "gas gangrene", "acute hemolytic streptococcal gangrene", "anaerobic cellulitis", "necrotizing fascitis", "vascular gangrene", "myofascial necrosis", "liquefaction necrosis", and the "fetid foot" are not entirely incorrect but do serve to obfuscate the correct medical definition of each specific entity. More basically, even the term "anaerobe" may be a source of confusion. By convention, an anaerobic organism is any microbe that requires reduced oxygen tension for growth and cannot grow on a solid cultural media, in an environment of 10% CO2, in air (18% oxygen).
