Oysters under threat from deadly herpes virus that is spreading around the world

THE world could soon be facing an oyster shortage as a deadly herpes virus is threatening to devastate oyster populations. The virus known as Ostreid herpesvirus 1 (OsHV-1), is impacting Pacific oysters, which is the most popular species to eat due to their large size and experts are worried it could continue to spread around … Continue reading Oysters under threat from deadly herpes virus that is spreading around the world

Mortality in Crassostrea gigas oysters in Ireland during 2012

OsHV-1 mu Var-related mortality is well described in several countries, including France. In Ireland, however, clear patterns in relation to the incidence and impact of this virus have been difficult to identify, at least in part because seawater temperatures rarely exceed 16 degrees C, a recognised threshold for OsHV-1 mu Var-related mortality, for prolonged periods. … Continue reading Mortality in Crassostrea gigas oysters in Ireland during 2012

Mass mortalities of unknown aetiology in Pacific oysters Crassostrea gigas in Port Stephens, New South Wales, Australia

From January to June 2013 and November to January 2014, mass mortalities were reported in Pacific oysters Crassostrea gigas cultivated in Port Stephens estuary, New South Wales, Australia. In some cases, 100% mortality was reported in both triploid and diploid C. gigas, although native species of oyster cultivated in the same areas remained unaffected. Histological … Continue reading Mass mortalities of unknown aetiology in Pacific oysters Crassostrea gigas in Port Stephens, New South Wales, Australia

Future CRC-P : advanced understanding of POMS to guide farm management decisions in Tasmania (project)

Pacific Oyster Mortality Syndrome (POMS) caused by the OsHV-1 virus was first detected in Tasmania in January 2016 with mass mortalities of cultured Pacific oysters on farms in several major oyster growing areas, including Pittwater, Pipeclay Lagoon, Blackman Bay and Little Swanport. Prior to this outbreak, Tasmanian oyster farms produced around four million dozen oysters … Continue reading Future CRC-P : advanced understanding of POMS to guide farm management decisions in Tasmania (project)

Oysters can get herpes, and it’s killing them. A deadly virus threatens to decimate oyster populations around the world

Oysters, a delicacy eaten on most coastlines of the world, are a multi-billion-dollar industry. They also are intriguing to study from a health perspective. Oysters feed by filtering tiny plankton from the surrounding water, processing up to 50 gallons per oyster daily. In doing so, they improve water quality and make their ecosystems healthier. But the water … Continue reading Oysters can get herpes, and it’s killing them. A deadly virus threatens to decimate oyster populations around the world

Complete genome sequence of vibrio coralliilyticus 58, isolated from Pacific oyster (Crassostrea gigas) larvae

We report here the complete genome of Vibrio coralliilyticus strain 58, which was originally isolated from inactive Pacific oyster (Crassostrea gigas) larvae in Japan. The assembled genome consisted of two chromosomes and one plasmid. These data will provide valuable information and important insights into the biodiversity of this organism. Hyoun Joong Kim, Ji Hyung Kim, Jin Woo Jun and al., Genome … Continue reading Complete genome sequence of vibrio coralliilyticus 58, isolated from Pacific oyster (Crassostrea gigas) larvae

Risk factors for mortality during the first occurrence of Pacific Oyster Mortality Syndrome due to Ostreid herpesvirus – 1 in Tasmania, 2016

The microvariant genotype of Ostreid herpes virus 1 (OsHV-1 μVar) has caused repeated seasonal outbreaks of mass mortality in Pacific oyster (Crassostrea gigas) populations in Europe, New Zealand and in New South Wales, Australia. The first occurrence of OsHV-1 related mortality in Tasmania, Australia was in January 2016; mortality was documented and multivariable logistic regression analysis was undertaken … Continue reading Risk factors for mortality during the first occurrence of Pacific Oyster Mortality Syndrome due to Ostreid herpesvirus – 1 in Tasmania, 2016
