Abstract
Two bullet-shaped viruses, isolated from eels, have been characterized physico-chemically, and their serological relationship to the other fish rhabdoviruses has been determined. Preparations of each virus contain truncated as well as bullet-shaped particles and the RNAs from these sediment at 18S and 4IS, respectively. As determined by PAGE, the virion polypeptide patterns for both viruses were indistinguishable, but were found to differ from those of the other fish rhabdoviruses. Using vesicular stomatitis virus polypeptides as internal markers, the molecular weights of the eel virus polypeptides were calculated to be > 150,000, 64,000, 49,000, 47,000 and 26,000. The two viruses are closely related to each other antigenically, but show no relationship to the other fish rhabdoviruses in neutralization tests.
