Oyster virus may cause devastating results for Tasmania

Oyster supplies in Tasmania are being threatened by a viral disease, which is concerning to producers ahead of the Christmas period. The concern in the sector stems from the fact that the virus causing Pacific Oyster Mortality Syndrome (POMS), which is harmless to humans, weakens oysters and makes them lose their ability to close their … Continue reading Oyster virus may cause devastating results for Tasmania

Development of a duplex Taqman real-time PCR assay for rapid identification of Vibrio splendidus-related and V. aestuarianus strains from bacterial cultures

To enable the rapid and accurate identification of Vibrio splendidus-related and V. aestuarianus strains associated with Pacific cupped oyster Crassostrea gigas mortality, we developed a duplex Taqman real-time PCR assay and evaluated its efficacy. This technique proved to be rapid, sensitive, and specific and will be particularly valuable for epidemiologic studies. Denis Saulnier, Sophie De … Continue reading Development of a duplex Taqman real-time PCR assay for rapid identification of Vibrio splendidus-related and V. aestuarianus strains from bacterial cultures

Preventive effect of three kinds of bacteriophages to control Vibrio coralliilyticus infection in oyster larvae

Vibrio corallilyticus is a well-known pathogen of coral. It is also infectious to a variety of shellfish species, including Pacific oyster (Crassostrea gigas) larvae. V. corallilyticus is remained to be a major constraint in marine bivalve aquaculture practice, especially in artificial seed production facility. Owing to the high mortality and contagious nature of the pathogen, … Continue reading Preventive effect of three kinds of bacteriophages to control Vibrio coralliilyticus infection in oyster larvae

Review of parasites and pathologies of the main bivalve species of commercial interest of Argentina and Uruguay, southwestern Atlantic coast

A systematic review of the parasites and pathologies of the main important commercially bivalve species from Argentina and Uruguay has been done. Bacteria, algae, Perkinsozoa, Haplosporidia, Ciliophora, Apicomplexa, Turbellaria, Trematoda, Cestoda and Nemertea have been found infecting natural populations of bivalve species. Disseminated neoplasia has been recorded in mussels from culture causing gonadal castration and … Continue reading Review of parasites and pathologies of the main bivalve species of commercial interest of Argentina and Uruguay, southwestern Atlantic coast

S.O.S. Pinna nobilis: a mass mortality event in western Mediterranean sea

A mass mortality event (MME) impacting the bivalve Pinna nobilis was detected across a wide geographical area of the Spanish Mediterranean Sea (Western Mediterranean Sea) in early autumn 2016. Underwater visual censuses were conducted across several localities separated by hundreds of kilometers along the Spanish Mediterranean coasts and revealed worrying high mortality rates reaching up … Continue reading S.O.S. Pinna nobilis: a mass mortality event in western Mediterranean sea

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
