Haliotid herpesvirus 1 (AbHV-1) | |
Haliotid herpesvirus 1 (AbHV-1), common name abalone herpesvirus, is a virus in the family Malacoherpesviridae.[1]
Discovery
In 2005 there was an outbreak of acute ganglioneuritis in an Australian population of the edible gastropod mollusc, abalone or Haliotis spp.[1] Potential herpesvirus particles had also been identified previously in Taiwan following mortalities in Haliotis diversicolor.[1] Using transmission electron microscopy, herpes-like particles were observed in ganglia of affected abalone and purified virions from moribund abalone nervous tissues were identified as resembling those of herpesviruses.[1]
A diagnostic PCR test has been developed to detect the abalone virus in 2010.[1] The test has detected viral DNA sequences in diseased abalone from separate geographical locations in Australia and in DNA isolated from a herpes-like virus found some time ago in Taiwan.[1] Savin et al. (2010)[1] have purified abalone virus particles and isolated and sequenced genomic DNA of the Haliotid herpesvirus 1.[1]
Description
Haliotid herpesvirus 1 has an icosohedral capsid approximately 100 nm in diameter, surrounded by a 150 nm diameter spiked viral envelope.[1]
Taxonomy
Haliotid herpesvirus 1 is the only known species in the genus Haliotivirus.[1]
Host range
Haliotid herpesvirus 1 infects the large edible sea snails known as abalones: Haliotis species such as Haliotis diversicolor.[1]
