“…In reality, furunculosis was the first fish infection for which the 'Koch postulates' were demonstrated more than a century ago (Austin & Austin, 2007;Bernoth et al, 1997). It was thought originally that the infection affected only salmonids, but it soon became evident that it was distributed worldwide and affected many other marine and freshwater fish species, such as the Atlantic cod (Gadus morhua), halibut (Hyppoglossus hyppoglossus), turbot (Scopthamus maximus), lamprey (Petromyzon marinus), carp (Cyprinus carpio), goldfish (Carassius auratus) and eel (Anguilla anguilla) among others (Austin & Austin, 2007;Bernoth et al, 1997;Godoy et al, 2010;Goldschmidt-Clermont et al, 2009;Noga, 2010;Wiklund & Dalsgaard, 1998).…”
