The genus Vibrio consists of a group of Gram-negative bacteria that naturally inhabitant aquatic environments worldwide. Among this diverse group of microorganisms are a few human pathogens, namely Vibrio cholerae and Vibrio parahaemolyticus. In addition, our lab studies some Vibrio species that cause disease in aquaculture (Vibrio tubiashii) and corals (Vibrio coralliilyticus). We are applying various modern molecular techniques to better-understand the virulence properties and environmental survival strategies of these pathogens. In addition, we are developing detection assays that can be used in aquaculture facilities to reduce the economic impact of vibriosis.
