Overwhelming sepsis with Vibrio vulnificus: a coastal pathogen in Oklahoma.

Vibrio vulnificus has been associated with three main clinical syndromes; primary septicemia; wound infection, and gastroenteritis. This organism has increased virulence for persons with underlying medical conditions that predispose to iron overload or an impaired immune system. Since the organism proliferates more readily in warm, coastal waters, such infections are more commonly found in those regions. Infection can result from the ingestion of contaminated, undercooked seafood; contact of a wound with seawater; or a puncture wound sustained from a contaminated surface. Vibrio infections rarely occur in inland areas, but when they do occur, they are usually a result of the contact of wounds with contaminated, brackish water or the ingestion of raw shellfish. Because infections with this organism occur less frequently in non-coastal regions, the diagnosis may not be suspected initially in susceptible individuals and a delay of treatment may result. We present a case of V. vulnificus sepsis occurring in a man with underlying liver disease and a history of row oyster consumption in Oklahoma and discuss the clinical manifestations of primary sepsis with this organism as well as prevention strategies.
