Polyphyletic origin of Vibrio vulnificus biotype 2 as revealed by sequence-based analysis

Appl Environ Microbiol. 2011 Jan;77(2):688-95. doi: 10.1128/AEM.01263-10. Epub 2010 Nov 19.

Abstract

A sequence-based analysis of seven housekeeping and virulence-related genes shows that the species Vibrio vulnificus is subdivided into three phylogenetic lineages that do not correspond with the biotypes and that biotype 2 is polyphyletic. These results support the reclassification of biotype 2 as a pathovar that would group the strains with pathogenic potential to develop vibriosis in fish.
