Abstract
RNA-dependent RNA polymerases were found to be associated with two salmonid rhabdoviruses: infectious hematopoietic necrosis (IHN) virus and the virus of hemorrhagic septicemia (VHS). The protein composition of these rhabdoviruses closely resembles that of rabies virus rather than that of vesicular stomatitis virus (McAllister and Wagner, 1975). The optimal temperature for in vitro transcription was found to be approximately 18 degrees C for IHN virus and approximately 15 degrees for VHS, closely approximating optimal temperatures for growth of these viruses in salmonid cells. Unlike vesicular stomatitis virus, manganese ion (1 mM) could be used as a divalent cation substitute for magnesium ion (5 mM). The in vitro transcription products of IHN and VHS viruses hybridized completely to the homologous genome but not at all to the heterologous genome.
