“…Farmed production of turbot is steadily increasing in Europe, mainly in France and Spain. Mortalities, attributed to marine birnavirus infections, have been reported in farmed turbot in Norway and Spain (Mortensen et al, 1990(Mortensen et al, , 1993Novoa et al, 1993a). The high dependence of some of these production plants on the importation of turbot juveniles from other geographical areas increases the risk of introducing "new" pathogens to unexposed marine populations.…”

Six marine birnaviruses isolated from turbot (Scophthalmus maximus) were compared with the infectious pancreatic necrosis virus reference strains Sp, Ab and WB from salmonid fish. This comparison was carried out by PAGE analysis of viral RNA and polypeptides and comparison of the reaction pattern with 4 monoclonal antibodies against the reference strains. High heterogeneity was found among the 6 isolates when comparing the RNA and polypeptide electrophoretic patterns and their reactions with the monoclonal antibodies. Most of the strains isolated from turbot could not be ascribed to any established serotype.

“…In Japan another aquatic birnavirus, yellowtail ascites virus (YAV), has caused significant mortalities anlong yellowtail fingerlings Seriola quinqueradiata (Egusa & Sorimachi 1986, Fujimaki et al 1986, Miyazaki 1986. Recently, IPNV has been associated with post-smolt mortality of Atlantic salmon in both Norway and Scotland (Krogsrud et al 1989, Smail et al 1992) and IPNVinduced disease has been experimentally transmitted to farmed turbot Scophthalmus maximus in France, Norway and Spain (Castric et al 1987, Mortensen et al 1993, Novoa et al 1993. In Norway, IPNV has been isolated regularly from halibut since 1989 (Rodseth 1992), often in connection with acute mortalities during weaning.…”

lnfectious pancreatic necrosis virus (IPNV), serotype NI, isolated from Atlantic halibut Hippoglossus hippoglossus, was used to bath-challenge (2 X l o 5 0 TCIDso ml-' for 1 h) Atlantic halibut fry of different sizes at 12 and 15°C in 3 trials. In all trials, the fry challenged at 15°C experienced significantly higher cumulative mortality compared to the unchallenged fry. The smallest fry (mean weight 0.1 g) also experienced significantly higher mortality compared to the controls when infected at 12"C, whilst the medium-sized fry (mean weight 1.0 g) did not display any mortality when infected at this temperature. The largest fry (mean weight 3.5 g) were only challenged at 15'C, resulting in 30 % cumulative mortality All fry infected at 15°C and the small fry infected at 12OC remained IPNV positive during the entire experimental period. In contrast, the medium-sized fry infected at 12 "C seemed to be able to clear the infection after 3 wk. Moribund and diseased fry showed clinical signs such as distended stomach and uncoordinated swimming. Patholog~cal findings included necrosis of the liver, kidney and intestine, but the pancreatic t~ssue was unaffected. lmmunohistochemistry revealed strong positive reactions to IPNV in the livers of challenged individuals.

“…This mixed infected fish has IPNV in brain tissue and VHSV in heart and kidney tissue. It was studied that turbot is susceptible to IPNV (Mortensen, 1993). This is also the first detection of IPNV in wild marine fish in Black Sea.…”

Existence of viral hemorrhagic septicemia virus (VHSV) has been recently reported in Turkey. A total of 5967 marine and freshwater fish were sampled to detect VHSV between 2007 and 2009 in the Black Sea region of Turkey. Of the 5967 fish, five fish tested positive by PCR reactions of tissue filtrates and supernatants of cell cultures showing CPE indicated by a specific 587 bp fragments from the glycoprotein (G) gene of VHSV. All the VHSV positive fish were turbots and none of the other fish species was VHSV positive. The nucleotide sequences among five isolates had shown 96% to 99% homology. In the phylogenetic study, all the new isolates were genogroup 1e. In this study, it was also discovered that an IPNV-VHSV mixed infected wild turbot.
