“…Pathogenic V. anguillarum-like strains have also been isolated from crustaceans and molluscs (4,5,19). Although vibriosis has been reported in complete freshwater culture (17), the disease is primarily a marine problem.…”

On the basis of plasmid composition as well as serological and biochemical properties, 26 strains identified as Vibrio anguillarum isolated from diseased fish could be assigned to two different groups. Except for three reference strains, these strains were isolated from Norwegian fish. The four strains isolated from rainbow trout (Salmo gairdnern), the only strain isolated from char (Salvelinus alpinus), and three of six strains isolated from Atlantic salmon (Salmo salar) harbored a plasmid of 47 megadaltons (MDa). Restriction endonuclease analysis showed that this plasmid and the virulence plasmid pJMl, carried by V. anguillarum strain 775, were very similar but not identical. Strains harboring the 47-MDa plasmid had nearly identical biochemical properties and were serotype 01. Strains isolated from reared coastal cod (Gadus morhua), turbot (Scophthalmus maximus), halibut (Hippoglossus hippoglossus), free-living saithe (Pollachius virens), and partly from reared Atlantic salmon differed from strains harboring the 47-MDa virulence plasmid by not containing this plasmid, by having different biochemical traits, and by being serotype 02. Rainbow trout which were experimentally infected with a strain isolated from cod suffering from vibriosis developed clinical symptoms similar to those in cod but quite different from those usually seen in rainbow trout.

“…33 We observed motionless, loss of appetite, swimming abnormality, hemorrhages on anal, ventral, lateral region, eyes and fin rots as seen previously disease outbreaks. 6,7,11,[34][35][36] Prolapsus of anus and adhesion in abdominal cavity also reported clinical symptoms [35][36][37][38] while we could not detected them, inflammation in liver's capsula was detected which is caused peritonitis. We argued that if infection would progressive, peritonitis could cause adhesion on abdominal cavity and may exudate should be seen.…”

“…Hyperemia, necrosis, mononuclear cell infiltration and melanin pigmentation were observed on 9, 11, 15th days in kidney tissues of control and infected fish groups. Experimental group; mononuclear cell infiltration and intensively desquamation of gill tissues were seen (Table 1, Fig 5,6) in the infected group. In some cases, atrophy and desquamation were noticed (Fig.…”

“…Austin and Austin 33 were reported that there is limited information about pathogenesis of L. anguillarum, that so; we would like to give macroscopic clinical signs and micro-scopic findings in different tissue and organs during experimental infection from one to 15 days. Generally, L. anguillarum causes about 40-70% mortality in natural infection for fish 6,25,26 , mortality could be reach 100% in experimental infections.15,27-30 Avci et al, 11 were reported that L. anguillarum caused 40% mortality in experimental infection by immersion and 55% mortality by intraperitoneal injection. As similar these findings, our results showed that mortality reached above 70% by intraperitoneally.…”

The rainbow trout production increased more than 100% in the last decade and total rainbow trout production was shown as 107.013 tons according to 2016 statics. According to Federation of European Aquaculture Producer, Turkey was determined as the biggest rainbow trout producer into the European Countries in 2016. Together with high production capacity, a number of outbreaks were reported causing L.anguillarum (Vibriosis). The pathogenesis of L. anguillarum which were experimentally infected in rainbow trout were examined during 15 days in our study. Spreading of agent that was injected with intraperitoneally into tissue and organs were studied by using histopathological methods. The mortality rate of agent was determined above 70% and deaths were seen in 2-3th days of experiment. In addition of these, liver, spleen, kidney and gills were determined as the most affected organs and tissues. In the present study was obtain for original pathological findings of L. anguillarum.

“…Vibrio anguillarum is an halophilic microorganism also adapted to fresh water and pathogenic for many fish (salmonids, trout, sea bass, etc.) in which it causes a septicemic-hemorrhagic syndrome (vibriosis) which is widespread from the Mediterranean to Pacific (OHNISHI and MUROGA, 1977;GIORGETTI and CESCHIA, 1982).…”

The fish pathogen Vibrio anguillarum causes a lethal infection in farmed fish characterized by hemorrhagic septicemia. There are no reports of experimental laboratory infections in warm-blooded animals. We investigated the effects of an intraperitoneal infection with different doses of a V. anguillarum suspension in mice and guinea pigs. The infection caused a 95-100% of mortality in 24-48 h. Hemorrhagic septicemia was observed at necropsy and confirmed by histological and hematological examination. Immunohistochemically positive bacterial clumps were detected exclusively in vessel lumen in all examined organs, including brain, and V. anguillarum was reisolated in pure culture from all organs, particularly from the kidney. Blood analysis showed erythropenia and leukopenia with granulocytosis in mice, platelet reduction and leukopenia with lymphocytosis in guinea pigs.
