Educational only: videos on MedicalVideos.com are for general information and are not medical advice. Always consult your own doctor about your health.
Two types of clinically distinct necrotizing fasciitis have been described. The most common form (type II) usually occurs in individuals with no concurrent medical illness. Many patients report a history of laceration, blunt trauma, or a surgical procedure as a predisposing factor. It is typically caused by group A Streptococcus (Streptococcus pyogenes). In contrast, type I is usually seen in patients with underlying diabetes and peripheral vascular disease. It is generally a polymicrobial infection; some commonly isolated organisms include Staphylococcus aureus, Bacteroides tragi/is, Escherichia coli, group A Streptococcus, and Pre vote/fa species. Crepitus is more common if anaerobic organisms, such as Clostridium perfringens or 8 tragi/is, are involved.
