Pseudomonas anguilliseptica infection as a threat to wild and farmed fish in the Baltic Sea

The transport of live fishes related to the growth of the fish farming industry worldwide may increase the transfer of previously known bacterial pathogens into new geographic areas and new host species, but also facilitate the introduction of completely new bacterial pathogens. Species belonging to the genera Vibrio and Aeromonas are well known in many countries, infecting a large number of fish species. Other bacterial fish pathogens like Pseudomonas anguilliseptica species, up to now considered less harmful, may constitute a potential threat to a developing fish farming industry, especially of European whitefish.
