Vibrio Species

The genus Vibrio contains several species, including V. parahaemolyticus and V. vulnificus known to be harmful to humans. Both species can cause gastrointestinal disease due to the consumption of raw shellfish, especially oysters. Our research focuses on the investigation of the ecology and diversity of pathogenic Vibrios that pose a significant threat to human health, and the development of forecasting models or early warning systems for seafood safety. The principal areas of research include:

Significant Prior Projects

Role of specific surface factors in virulence and persistence of V. vulnificus in the environment.
