Vibrio cholerae, V. vulnificus and V. parahaemolyticus are responsible for the majority of Vibrio-related illnesses in humans. V. cholerae, usually transmitted to humans through contaminated water is still the leading cause of Vibrio-associated illnesses world-wide, and continues to be a major public health concern in developing countries. In other parts of the world a significant increase in the incidence of seafood-related illnesses attributed to non-cholerae Vibrios, mainly V. parahaemolyticus and V. vulnificus, has been noted since the late 1990s. Climate change affecting both global and local environments has the potential of affecting the natural habitat and increasing the incidence and spread of these emerging pathogens. Increases in local water temperature, or alterations in biogeochemical processes such as ocean carbonate chemistry and changes in phytoplankton, and zooplankton abundance and species, can directly or indirectly impact Vibrio spp. Such impacts include increases in Vibrio spp prevalence, expansion of pathogen range, or alterations in environmental niches that in turn may force genetic adaptation and selection of more virulent strains.
