ABSTRACT
The family Vibrionaceae now contains > 70 species, of which at least 12 are human pathogens (Table 1). This family earlier comprised also of Aeromonas spp. and Plesiomonas spp. but, by comparison of DNA-sequences, these now form their own families, Aeromonadaceae and Plesiomonas, belonging to Enterobacteriaceae. All three families, however, have water and waterassociated animals and plants as their natural habitat, and may cause food-associated infections.
