During two long-term bacteriological surveys in European sea bass (Dicentrarchus labrax L.) and gilthead sea bream (Sparus aurata L.) culture facilities on the Spanish Mediterranean coast, four different species of Pseudoalteromonas were found in the internal organs of animals. Pseudoalteromonas undina, Pseudoalteromonas haloplanktis, P. espejiana and Pseudoalteromonas sp. were isolated from 9% out of 177 European sea bass and 11.7% out of 547 gilthead sea bream and they were recovered as pure cultures in 50% of isolations. Among fish with positive bacterial growth, Pseudoalteromonas was more prevalent in sea bass showing clinical signs (27.7%) and in gilthead sea bream without clinical sig…
