Abstract

Vibrio species are bacteria found in coastal marine waters that cause harmful health issues in humans. In particular, there are three species Vibrio vulnificus, Vibrio cholerae and Vibrio parahaemolyticus that are of increasing concern. Each of these species causes different medical issues, with V. vulnificus, while a rare infection, being the most detrimental. We are characterizing 468 isolates of V. vulnificus obtained from the Great Bay Estuary (GBE) of NH since 2007 using whole genome analysis and environmental data. While environmental data and V. vulnificus levels have been monitored for years in the GBE, we are the first to analyze this information and have demonstrated that that the level of pollution, temperature and salinity all impact V. vulnificus levels. Furthermore, that strains of V. vulnificus are able to survive under different environmental limits than previously thought. These findings suggest that further analysis is important to evaluate potential human health risk.
