Lymphocystivirus cause mass mortality events like megalocytiviruses and ranaviruses, fish with lymphocystis exhibit grossly visible papilloma-like skin lesions which substantially reduce their commercial value. No vaccines are currently available for lymphocystis viruses. Group: dsDNA The genus "Lymphocystivirus" has only one species: "Lymphocystis disease virus 1" (LCDV-1), but Lymphocystis disease virus 2 (LCD-2) is another virus that has been proposed as a second member. LCDV-1 infects European flounder "Platichthys flesus" and European plaice ("Pleuronectes platessa"). LCDV-2 infects the common dab ("Limanda limanda"). A third species Lymphocystis disease virus C has also been proposed based on the relative lack of sequence similarity of
Remo flounder Remo flounder The Remo flounder, "Oncopterus darwinii", is an edible flatfish of the family Pleuronectidae. It is a demersal fish that lives on bottoms at depths of between . Its native habitat is the southwestern Atlantic along the southeast coast of South America, from Santa Catarina, Brazil in the north to the San Matías Gulf, Argentina in the south. It can reach in length. The Remo flounder is a righteyed flounder and so has both its eyes on the right-hand side of its body.
