Vibriosis is an important disease of farmed and wild fish, caused by species of the genus Vibrio. During December 2000, high mortalities were observed in a wild population of big scale sand smelt Atherina boyeri in Limnos, Greece. The microbiological analysis of the moribund fish resulted in the isolation of a pure culture of Vibrio anguillarum. The bacterium was identified by bacteriological procedures and slide agglutination reaction. Focal or more extensive necrosis was found in almost all organs, in all fish examined and the retina of the eyes appeared corrugated. The pathogenicity of the strain for sea bass was confirmed by bath challenge causing mortalities up to 97%. Factors contributing to the outbreak of the disease were considered to be the presence of parasites (Platyhelminthes) in the intestinal tract. No simultaneous infection at a fish farm in the vicinity had been reported. However, since there are disease interactions between wild and cultured fish, infected wild fish, can act as a reservoir of the pathogen.
