Vibrios are ubiquitous in marine and estuarine environments and are commonly present in or on shellfish and other seafood. They are present in the environment as free-living and associated with different substrata (Tamplin et al., 1990). Epibionts are able to survive in the natural environment longer than free-living forms, and by means of adhesive strategies, they can adapt to adverse conditions, eg organic matter limitation (Roszak and Colwell, 1987; Carman and Dobbs, 1997). The colonisation of planktonic copepod integument by Vibrio spp. is a well-described phenomenon especially in what concerns the attachment to the copepods in faecal polluted and non-polluted coastal zones (Kaneko and Colwell, 1975; Venkateswaran et al., 1989; Tamplin et al., 1990; Carli et al., 1993; Maugeri et al., 2004). Larger numbers of V. cholerae are associated with zooplankton than are found in the surrounding water column (Huq et al., 1983). The dispersion of eggs and faecal pellets should contribute to bacterial diffusion in the aquatic environment.Interest in the occurrence of potentially pathogenic vibrios is high from an epidemiological and ecological point of view. Vibrios able to cause human disease include the cholera toxin-producing strains of V. cholerae, that are responsible for epidemic/pandemic cholera, thermostable direct hemolysin-producing strains of V. parahaemolyticus, a leading cause of gastro-enteritis and V. vulnificus, which can cause sepsis and serious wound infections. The transmission of V. cholerae strains from their environmental reservoir to humans through water sources or seafood has been demonstrated. Other non-epidemic Vibrio species, including
