Comparative and evolutionary analysis of an adapter molecule MyD88 in invertebrate metazoans

The myeloid differentiation factor 88 (MyD88) is an essential adapter in Toll-like receptor (TLR) signalling pathways, with TLR the first pattern-recognition receptor (PRR) that was discovered in Drosophila. In the present study, a MyD88 gene was identified and characterized from a commercially important shellfish, Scapharca subcrenata, including a DEATH domain and TIR domain conserved within … Continue reading Comparative and evolutionary analysis of an adapter molecule MyD88 in invertebrate metazoans

The first invertebrate NFIL3 transcription factor with role in immune defense identified from the Hong Kong oyster, Crassostrea hongkongensis

NFIL3 (nuclear factor interleukin 3-regulated) is a basic leucine zipper type transcription factor that mediates a variety of immune responses in vertebrates. However, the sequence information and function of NFIL3 homologs in invertebrates, especially mollusks, remains unknown. In the present study, the first NFIL3 homolog was identified in a marine mollusk, Crassostrea hongkongensis (designated as … Continue reading The first invertebrate NFIL3 transcription factor with role in immune defense identified from the Hong Kong oyster, Crassostrea hongkongensis

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

Manual of diagnostic tests for aquatic animals

Valid laboratory results are essential for Aquatic Animal Health Services to implement a range of programmes for diagnosis, surveillance and trade. This Manual of Diagnostic Tests for Aquatic Animals (Aquatic Manual) supports Aquatic Animal Health Services to provide effective laboratory testing for pathogenic agents that may adversely affect aquatic animals. (...) The World Organisation for Animal Health … Continue reading Manual of diagnostic tests for aquatic animals
