French scallops: a new host for ostreid herpesvirus-1.

Infectious diseases of marine molluscs and host responses as revealed by genomic tools.

More and more infectious diseases affect marine molluscs. Some diseases have impacted commercial species including MSX and Dermo of the eastern oyster, QPX of hard clams, withering syndrome of abalone and ostreid herpesvirus 1 (OsHV-1) infections of many molluscs. Although the exact transmission mechanisms are not well understood, human activities and associated environmental changes often corr...

Ostreid herpesvirus 1 detection and relationship with Crassostrea gigas spat mortality in France between 1998 and 2006

Since its molecular characterisation, Ostreid herpesvirus 1 (OsHV-1) has been regularly detected in Crassostrea gigas in France. Although its pathogenicity was demonstrated on larval stages, its involvement during mortality outbreaks at the juvenile stage was highly suspected but not evidenced. To investigate mortality outbreaks, the French National Network for Surveillance and Monitoring of Mo...

Ostreid herpesvirus 1 infection in farmed Pacific oyster larvae Crassostrea gigas (Thunberg) in Korea.

Rapid and sensitive detection of ostreid herpesvirus 1 in oyster samples by real-time PCR.

Herpes and herpes-like virus infections have been reported in various marine mollusc species associated with high mortality rates. Following the characterisation and genome sequencing of ostreid herpesvirus 1 (OsHV-1), specific diagnostic tools have been developed based on conventional PCR techniques or in situ hybridisation. We have now developed a real-time PCR assay for rapid, sensitive and ...

Ostreid herpesvirus: A pathogen of oysters

Ostreid Herpesvirus-1 (OsHV-1), OsHV-1 μvar and other variants are herpesviruses causing heavy mortalities, with losses ranging from 50 to 100%, on Pacific oyster (Crassostrea gigas), an important species worldwide cultured. Ostreid Herpesvirus-1 is one of the top 50 largest viral genome; OsHV-1 μvar is a variant of the virus OsHV-1 showing a systematic deletion of 12/13 base pairs sequence bet...
