Unusual Case of Necrotizing Fasciitis Caused by Vibrio choleraeO137

ABSTRACTWe report a case of necrotizing fasciitis caused by Vibrio choleraeO137 in an immunocompromised 49-year-old man. The infection was acquired following a minor traumatic injury and exposure to seawater during the summer of 2009 in Italy. Although highly immunocompromised, the patient survived. The strain was cytotoxic, invasive, and adhesive and contained a fragment of the El Tor-like hemolysin (El Tor hlyA) gene.
