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

The Whole-Genome and Transcriptome of the Manila Clam (Ruditapes philippinarum)

The manila clam, Ruditapes philippinarum, is an important bivalve species in worldwide aquaculture including Korea. The aquaculture production of R. philippinarum is under threat from diverse environmental factors including viruses, microorganisms, parasites, and water conditions with subsequently declining production. In spite of its importance as a marine resource, the reference genome of R. philippinarum for … Continue reading The Whole-Genome and Transcriptome of the Manila Clam (Ruditapes philippinarum)

Integrating the Vibrio-resistance phenotype and gene expression data for discovery of markers used for resistance evaluation in the clam Meretrix petechialis

In this study, gene expression data were used to select resistance-associated markers that indicate resistance phenotypes in the clam Meretrix petechialis. A total of 1772 clams from 23 full-sibling families were subjected to a Vibrio challenge test, and the results showed significant variation in resistance to vibriosis among different families. Three of the most resistant … Continue reading Integrating the Vibrio-resistance phenotype and gene expression data for discovery of markers used for resistance evaluation in the clam Meretrix petechialis

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

OsHV-1 and notifiable protozoa in healthy Crassostrea corteziensis cultured in two distant areas of the Gulf of California

Infectious diseases have been a major limiting factor for large scale production of oyster farming. Several factors have contributed to the emergence and spread of infectious diseases in all cultivation sites around the world. Therefore, the prevention and control of diseases has become a priority for the sustainability of global aquaculture. Crassostrea corteziensis is a … Continue reading OsHV-1 and notifiable protozoa in healthy Crassostrea corteziensis cultured in two distant areas of the Gulf of California

Metabolomic applications in marine mollusc development and aquaculture

Metabolomics is a rapidly emerging discipline within functional genomics to better understand biochemical phenotypes across a range of biological systems. The approach has many demonstrated applications in aquatic biology, but has not yet been applied to study early lifestages of marine molluscs. This Thesis evaluates metabolomics as an approach to characterise early lifestage phenotypes of … Continue reading Metabolomic applications in marine mollusc development and aquaculture

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
