“…In the last decade, this pathogen has been isolated during the cold periods from turbot ( Psetta maxima ), another major marine fish species cultured in Southern Europe (López-Romalde et al , 2003a), from black spot seabream Pagellus bogaraveo (López-Romalde et al 2003b) and from cod Gadus morhua (Ferguson et al , 2004). Moreover, different microbiological studies have associated infection by P. anguilliseptica with the etiology of several outbreaks of “winter disease”, a pathological condition affecting gilthead seabream reared in Southern Europe during the winter season (Berthe et al , 1995; Dómenech et al , 1997, 1999; López-Romalde et al , 2003a).…”

“…Few descriptions of the histopathological changes caused by P. anguilliseptica can be found in the literature. Pathology of P. anguilliseptica infection has been described for Japanese and European eels (Miyazaki and Egusa, 1977; Ellis et al , 1983) and cod (Ferguson et al , 2004), but not for turbot.Therefore, the aim of this study was to describe the pathology induced by P. anguilliseptica in turbot and to analyze its similarity with that of other fish species.…”

Experimental infection with Pseudomonas anguilliseptica was performed both by intraperitoneal (i.p.) and bath route on juvenile turbot (Psetta maxima) in order to evaluate the pathology induced. Turbot was found to be sensitive to i.p. challenge (1.7×106 CFU/fish) but no to bath exposure. The i.p. challenge induced septicaemic infection and mortality. Externally, moribund fish showed distended abdomen and pale areas at day 9. The gross pathological internal signs present were abundant ascitic fluid in the peritoneal cavity, pale and enlarged spleen, pale and friable liver, and congestive and dilated gut with yellowish exudates. On histopathological examination, bacterial invasion was common in all the tissues studied but the most prominent pathological changes were observed in gut, spleen and kidney after 7 day with features of necrosis. The immunohistochemical findings support the widespread localization of the bacteria after the i.p. injection since the P. anguilliseptica was detected in spleen from day 1 post injection, in liver, kidney and gut from day 4, in muscle from day 7 and in brain from day 9. The difficulties in infecting healthy fish by bath challenge can be explained by the opportunistic nature of this pathogen.

“…Water temperature was approximately 16-18°C when mortality increased, and mortality began to decrease as the water temperature exceeded 20°C. Earlier studies have shown relationships between bacterial diseases in several fish species and water temperature (Tort et al, 1996;Domenech et al, 1997Domenech et al, , 1999Haenen and Davidse, 2001;Ferguson et al, 2004). In the case of sea bream in Spain, water temperatures were below 12°C during outbreaks, and the disease persisted until the water temperature increased to 18-20°C (Doménech et al, 1997(Doménech et al, , 1999.…”

In recent years, several southern coastal fish farms in Korea have experienced 2-30% mortality in striped beakperch suffering from bacterial infections during the spring. In this study, we identified a bacterium isolated from diseased striped beakperch as Pseudomonas anguilliseptica via a biochemical test and 16S rDNA sequence analysis. To evaluate the susceptibility of striped beakperch to P. anguilliseptica, 4.39×10 7 or 4.39×10 5 CFU/fish of bacteria were injected intraperitoneally at 18 ± 1°C into fish weighing 5.5 g. Cumulative mortalities reached 100% and 45% in the 4.39×10 7 and 4.39×10 5 CFU/fish infected groups, respectively. Experimentally infected fish showed cell-associated inflammation as well as bacteria in the kidneys and spleen. This study is the first report of striped beakperch mortality caused by P. anguilliseptica, which has pathogenicity in striped beakperch.

“…Although P. anguilliseptica was initially considered a pathogen closely associated with eel culture it appeared that this pathogen infects a number of different fish species in different water areas. It has been isolated from farmed fish species, like ayu (Plecoglossus altivelis) 6 , cod (Gadus morhua) 7 , gilthead seabream (Sparus aurata) 8 , sea bass (Dicentrarchus labrax), turbot (Scophthalmus maximus) 9 , striped beakperch (Oplegnathus fasciatus) 10 and recently from lumpsucker (Cyclopterus lumpus) 11 .…”

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.
