Pathogenesis of Vibrio vulnificus

Abstract

This review describes the factors which are currently recognized as being central to the virulence of the human pathogen, Vibrio vulnificus. This estuarine/marine bacterium occurs in high numbers in molluscan shellfish, primarily oysters, and its ingestion in raw oysters results in a ca. 60% mortality in those persons who are susceptible to this bacterium. The organism is also able to produce life-threatening wound infections. We describe here the nature of both the wound and primary septicemia infections, the virulence factors known or believed to be involved in these infections, possible immunotherapy, and some thoughts on the possibility that not all strains of this pathogen are virulent.
