|Abstract:||Species belonging to the genus Vibrio are Gram-negative bacteria that grow in estuaries and marine waters (Vora et al., 2005). They may be found as free-living organisms or associated with zooplankton and phytoplankton (Oberbeckmann et al., 2010). Although many bacteria in the genus Vibrio (referred to generically as “vibrios”) are not harmful to humans, there are a few strains that are especially harmful. Of the more than 65 species of Vibrio, at least 12 are pathogenic to humans and have been associated with food-borne disease (Chakraborty et al, 2000). Vibrio species are particularly infectious in unclean waters (without chlorine) (Morse, 1995) and in heavily populated areas (Hlady and Klontz, 1996). These pathogenic Vibrio species include Vibrio cholerae, the infectious agent responsible for cholera (Chakraborty et al., 2000), Vibrio vulnificus, associated with severe necrotizing wound infection due to invasive fulminating septicemia, and Vibrio parahaemolyticus, one of the world’s leading causes of food-borne illnesses, septicemia, and wound infections (Carbulotto et al. 2010). In the past, several predictive models have been used to describe the dynamics of Vibrio species in the context of environmental impact. For example, Hsieh et al., used a model based on factors such as temperature, salinity and nutrients within the Neuse River (North Carolina, USA) to assess the population dynamics of Vibrio. The Center for Disease control has also recommended that seafood be properly cooked to minimize the risk of ingesting harmful Vibrio as well as avoiding exposure of skin abrasions to warm seawaters (2009).|
