Novirhabdovirus is one of the genera of ''Rhabdoviridae'', along with Vesiculovirus, known to infect aquatic hosts. They can be transmitted from fish to fish or by waterborne virus, as well as through contaminated eggs. Replication and thermal inactivation temperatures are generally lower than for other rhabdoviruses, given the cold-blooded nature of their hosts. Hosts include a large and growing range of marine and freshwater fish.〔Whelan, Gary E. (Viral Hemorrhagic Septicemia (VHS) Briefing Paper ) Michigan Department of Natural Resources. Retrieved on 2007-07-15.〕 A common characteristic among novirhabdoviruses is the NV gene, an approximately 500-nucleotide-long gene located between the glycoprotein (G) and polymerase (L) genes. The expected protein encoded by the NV gene is not found in the virions, leading to its being named a "nonvirion" (NV) protein. This is the origin of the genus name Novirhabdovirus. The four recognized species of the genus are Hirame rhabdovirus, currently isolated to Japan, Infectious hematopoietic necrosis virus (IHNV), enozootic to North America but now present in Europe and Asia, as well, Viral hemorrhagic septicemia virus (VHSV), enzootic to Europe, but now present in North America and Asia, as well, and snakehead rhabdovirus (SHRV).〔(Rhabdoviridae ) ICTVdB Index of Viruses, Version 28, June, 2002.
