The Malacoherpesviridae are a family of DNA viruses that cause diseases in molluscs.
The family name Malacoherpesviridae is derived from Greek word ‘μαλακός (malacos) meaning ‘soft’ and from Greek word ‘μαλάκιον (malakion) meaning ‘mollusc.
Within this family two species have been described: Ostreid herpesvirus 1 in 2009 and Haliotid herpesvirus 1 in 2010.
Malacoherpesviridae may have the ability to infect across species, a feature not typically observed in vertebrate herpesviruses. This ability appears to be restricted to related mollusc species.
