“…McAuslan & Smith (1968) have demonstrated, however, that frog virus 3 DNA is associated with the nucleus in BHK 2 I cells. Nuclear involvement has not been observed in iridescent virus-infected cells (Kelly & Robertson, 1973 I would like to thank Mrs Elizabeth M o r t o n and Mrs Thelma Lescott, together with M r M. G.

“…These viruses were originally grouped together based on their icosahedral symmetry, large double-stranded DNA genomes and the presence of non-cellular-membranederived envelopes (Kelly & Robertson 1973). Their unique replication strategy, involving both nuclear and cytoplasmic phases (Murti e t al.…”

Three iridovirus-like agents associated with systemic infections in fish were examined by electron microscopy, gel electrophoresis of virion polypeptides and serological cross reactions with hyperimmune rabbit sera. The virus associated with epizootic hematopoietic necrosis (EHN) of redfin perch Perca fluviatilis in Australia, the virus from sheatfish Siluris glanis in Germany and a recently isolated iridovirus-like agent from catfish Ictalurus melas in France shared similar virion morphology and size, number and weight of structural polypeptides and common antigens as shown by cross immunofluorescence tests. The characteristics of these 3 piscine viruses and their strilung similarity to frog virus 3, the type strain of the Ranavirus genus in the family Iridoviridae, suggest that they should be grouped into the same genus. The presence of similar agents in fish and amphibians emphasizes the potential adaptation and evolution of serious viral pathogens among these aquatic hosts and further complicates programs aimed at preventing or controlling the spread of fish viruses.

“…It is morphologicaly similar to, but larger than, frog virus 3 (Darlington,Granoff & Breeze,I966;Lunger & Came,I966) and Tipula iridescent virus (Almeida,Waterson & Plowright,I967). On the basis of this rather limited information, ASFV has been classified as a member of the icosahedral cytoplasmic deoxyribovirus group (Wilner, 1969;Kelly & Robertson, 1973). Because of the problems involved in purifying the virus, however, precise biochemical characterization has not been attempted (Hess,I97 I) so that comparison with members of the icosahedral deoxyriboviruses at present is tentative.…”

SUMMARYMethods for the purification of African swine fever virus (ASFV) and its dissection into two fractions are described. The difficulties which have been encountered previously in attempts to purify the virus, namely contamination with large amounts of cellular constituents and aggregation of the virus particles, have been overcome by treatment with Tween 8o and by the use of I i-NaC1 in the sucrose gradients. Five major polypeptides, tool. wt. Ioax I25 (VP1), 76 (VP2), 50 (VP3), 44 (VP4) and 39 (VPs) were found in the purified particles. The virus was dissected by treatment with Nonidet NP 40 into (a) a fraction which had the appearance of an empty capsid shell and contained the polypeptides VP2 and VP3 and (b) a structure containing VP 1 and VP4. The location of VPn was not ascertained.
