Haliotid herpesvirus 1 (AbHV-1), common name abalone herpesvirus, is a virus in the family Malacoherpesviridae.

Contents

Discovery

In 2005 there was an outbreak of acute ganglioneuritis in an Australian population of the edible gastropod mollusc, abalone or Haliotis spp. Potential herpesvirus particles had also been identified previously in Taiwan following mortalities in Haliotis diversicolor. 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.

A diagnostic PCR test has been developed to detect the abalone virus in 2010. 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. Savin et al. (2010) have purified abalone virus particles and isolated and sequenced genomic DNA of the Haliotid herpesvirus 1.

Description

Haliotid herpesvirus 1 has an icosohedral capsid approximately 100 nm in diameter, surrounded by a 150 nm diameter spiked viral envelope.

Taxonomy

Haliotid herpesvirus 1 is the only known species in the genus Haliotivirus.

Host range

Haliotid herpesvirus 1 infects the large edible sea snails known as abalones: Haliotis species such as Haliotis diversicolor.
