Survey of bivalve molluscs for Bonamia spp. and other parasitic pathogens in Florida east coast lagoons

A 2007 study of Suminoe (Crassostrea ariakensis) and eastern (Crassostrea virginica) oysters exposed to Indian River Lagoon (IRL), Florida waters revealed the presence of Bonamia spp. in exposed oysters. In 2010, a survey of oysters and other bivalves (n = 721, 18 species) was conducted in the southern IRL (10 sites) and in the more … Continue reading Survey of bivalve molluscs for Bonamia spp. and other parasitic pathogens in Florida east coast lagoons

Survey of Potential Reservoir Species for the Oyster Parasite Multinucleate Sphere X (Haplosporidium nelsoni) in and Around Oyster Farms in the Damariscotta River Estuary, Maine

In the summer of 2010, the Damariscotta River Estuary, ME, experienced the first large multinucleate sphere X disease (Haplosporidium nelsoni) outbreak in commercial stocks of the eastern oyster (Crassostrea virginica). In 2012, biofouling organisms were sampled in and around the commercial oyster operations with the intent of looking for the presence of the parasite to … Continue reading Survey of Potential Reservoir Species for the Oyster Parasite Multinucleate Sphere X (Haplosporidium nelsoni) in and Around Oyster Farms in the Damariscotta River Estuary, Maine

Identification of cvSI-3 and evidence for the wide distribution and active evolution of the I84 family of protease inhibitors in mollusks

Protease inhibitors are an extremely diverse group of proteins that control the proteolytic activities of proteases and play a crucial role in biological processes including host defenses. The I84 family of protease inhibitors in the MEROPS database currently consists of cvSI-1 and cvSI-2, two novel serine protease inhibitors purified and characterized from the eastern oyster … Continue reading Identification of cvSI-3 and evidence for the wide distribution and active evolution of the I84 family of protease inhibitors in mollusks

Pathogenic enteric viruses in louisiana oysters and environmental waters

Norovirus (NoV) and pathogenic enteroviruses are the major causes of gastroenteritis in humans worldwide, and are usually transmitted through direct or indirect exposure to raw or partially treated sewage. Filter-feeding shellfish concentrate virus particles from the water and transmit them to humans. The occurrence of norovirus GI and GII and fecal indicators in Louisiana eastern … Continue reading Pathogenic enteric viruses in louisiana oysters and environmental waters

What is going on with Perkinsus marinus in the Gulf of Mexico?

The National Oceanic and Atmospheric Administration (NOAA) Status and Trends Mussel Watch Program sampled the largest oysters in nearly every major US coastal lagoon and estuary in the Gulf of Mexico once during the winter from 1986 to 2010. This contribution examines trends in the principal oyster disease in the Gulf of Mexico, Dermo, caused … Continue reading What is going on with Perkinsus marinus in the Gulf of Mexico?
