The polypeptide and RNA compositions of purified virions of eel virus European were compared to those of three strains (VR-299, SP and AB) of infectious pancreatic necrosis virus (IPNV) isolated from trout. All three IPNV strains could be distinguished by the relative mobilities of either the virion polypeptides or the double-stranded RNA genome segments. The eel virus had a similar polypeptide profile to strain AB IPNV but differences between the two viruses in the migration of genome segments indicated each was unique. Annual epizootics among pond-cultured Japanese els (Anguilla japonica) in Shizuoka pre-fecture, Japan have been reported since 1969 (Egusa, 1970). Environmental nd physiological factors alone or in combination with a bacterium of the genus Cytophaga were believed to be the major causes of the observed epizootics (Egusa et al., 1971; Egusa, 1976). Virological examin-ations of diseased eels, however, revealed the presence of a previously undescribed virus (Sano, 1976). Examinations of eels from farms in 10 different locations indicated that this same virus was present in several populations of cultured eels in Japan (Sano et al., 1981). This disease out-break followed the importation of European eels (Anguilla anguilla) to Shizuoka prefecture. The
