Abstract

Vibrio spp. cause frank and opportunistic infections of humans through exposure to seafood and seawater. Due to their natural occurrence in coastal environments, traditional indicator organisms, such as E. coli, do not predict their presence. This problem has complicated public health initiatives aimed at reducing the impact of illnesses from Vibrio spp. In the U.S., V. vulnificus has received extensive study due to the severity of its disease in humans. Its numbers increase with warmer summer temperature, and decline to nondetectable levels in colder winter months. In environments with salinities greater than 20 ppt, V. vulnificus numbers decline to levels that do not pose human health risks. A similar response to temperature has been observed for pathogenic strains of V. parahaemolyticus, where recent outbreaks of illness have been associated with El Niño weather conditions. In addition, temperature-induced plankton blooms have been linked to epidemic cholera in certain geographical regions of the world. New research shows that seawater temperature and salinity can be used to develop mathematical models of V. vulnificus incidence in coastal environments. Similar efforts might be extended to other Vibrio spp. to develop indicators that predict human health risk, as well as ecosystem integrity.
