title: Morphogenesis and fine structure of eel virus (Berlin), a member of the proposed Birnavirus group.
abstract: Eel Virus (Berlin) is associated with the occurrence of skin tumors in European eels. The genome of the virus consists of two segments of double-stranded (ds) RNA. The agent is assembled exclusively in the cytoplasm. Isometric particles with a diameter of 61 nm and in addition tubular structures and smaller particles were observed. The virion has a single shell: its capsid is composed of 132 interconnected morphological units with T = 13 dextro symmetry. According to particle size and bipartite nature of the genome, this virus has to be assigned to the tentatively proposed group of bisegmented ds RNA animal viruses.
