Bacterial diseases in marine bivalves ArchiMer
Travers, Marie-agnes; Miller, Katherine Boettcher; Roque, Ana; Friedman, Carolyn S..
Bivalve aquaculture is seriously affected by many bacterial pathogens that cause high losses in hatcheries as well as in natural beds. A number of Vibrio species, but also members of the genera Nocardia and Roseovarius, are considered important pathogens in aquaculture. The present work provides an updated overview of main diseases and implicated bacterial species affecting bivalves. This review focuses on aetiological agents, their diversity and virulence factors, the diagnostic methods available as well as information on the dynamics of the host-parasite relationship.

Complementary approaches to diagnosing marine diseases: a union of the modern and the classic ArchiMer
Burge, Colleen A.; Friedman, Carolyn S.; Getchell, Rodman; House, Marcia; Lafferty, Kevin D.; Mydlarz, Laura D.; Prager, Katherine C.; Sutherland, Kathryn P.; Renault, Tristan; Kiryu, Ikunari; Vega-thurber, Rebecca.
Linking marine epizootics to a specific etiology is notoriously difficult. Recent diagnostic successes show that marine disease diagnosis requires both modern, cutting-edge technology (e.g. metagenomics, quantitative realtime PCR) and more classic methods (e.g. transect surveys, histopathology and cell culture). Here, we discuss how this combination of traditional and modern approaches is necessary for rapid and accurate identification of marine diseases, and emphasize how sole reliance on any one technology or technique may lead disease investigations astray. We present diagnostic approaches at different scales, from the macro (environment, community, population and organismal scales) to the micro (tissue, organ, cell and genomic scales). We use disease...

Detection of ostreid herpesvirus 1 DNA by PCR in bivalve molluscs: A critical review ArchiMer
Batista, Frederico; Arzul, Isabelle; Pepin, Jean-francois; Ruano, Francisco; Friedman, Carolyn S.; Boudry, Pierre; Renault, Tristan.
Herpes-like viral infections have been reported in different bivalve mollusc species throughout the world. High mortalities among hatchery-reared larvae and juveniles of different bivalve species have been associated often with such infections. The diagnosis of herpes-like viruses in bivalve molluscs has been performed traditionally by light and transmission electron microscopy. The genome sequencing of one of these viruses, oyster herpesvirus 1 (OsHV-1), allowed the development of DNA-based diagnostic techniques. The polymerase chain reaction (PCR) has been used for the detection of OsHV-1 DNA in bivalve molluscs at different development stages. In addition, the PCR used for detection of OsHV-1 has also allowed the amplification of DNA from an OsHV-1...

First evaluation of resistance to both a California OsHV-1 variant and a French OsHV-1 microvariant in Pacific oysters ArchiMer
Divilov, Konstantin; Schoolfield, Blaine; Morga, Benjamin; Dégremont, Lionel; Burge, Colleen A.; Mancilla Cortez, Daniel; Friedman, Carolyn S.; Fleener, Gary B.; Dumbauld, Brett R.; Langdon, Chris.
Background Variants of the Ostreid herpesvirus 1 (OsHV-1) cause high losses of Pacific oysters globally, including in Tomales Bay, California, USA. A suite of new variants, the OsHV-1 microvariants (μvars), cause very high mortalities of Pacific oysters in major oyster-growing regions outside of the United States. There are currently no known Pacific oysters in the United States that are resistant to OsHV-1 as resistance has yet to be evaluated in these oysters. As part of an effort to begin genetic selection for resistance to OsHV-1, 71 families from the Molluscan Broodstock Program, a US West Coast Pacific oyster breeding program, were screened for survival after exposure to OsHV-1 in Tomales Bay. They were also tested in a quarantine laboratory in...

Summer seed mortality of the Pacific oyster, Crassostrea gigas Thunberg grown in Tomales Bay, California, USA : the influence of oyster stock, planting time, pathogens, and environmental stressors ArchiMer
Burge, Colleen; Judah, Linda; Conquest, Loveday; Griffin, Frederick; Cheney, Daniel; Suhrbier, Andrew; Vadopalas, Brent; Olin, Paul G.; Renault, Tristan; Friedman, Carolyn S..
Summer seed mortality (SSM) has occurred yearly in Tomales Bay, California since 1993. SSM has resulted in up to 90% cumulative losses, and has been associated with extreme temperature, phytoplankton blooms, and an oyster herpesvirus. In this study, three stocks of Pacific oysters were planted at three sites in California (Inner Tomales Bay, Outer Tomales Bay, and Bodega Harbor) in October of 2000 (Fall) and April of 2001 (Spring) and monitored for mortality, growth, and health status. In April of 2001, a similar study was conducted in Totten Inlet, WA state using cohorts of oysters planted in California; animals were monitored for mortality and growth. Temperature data were collected at all sites; phytoplankton abundance data were collected at the...
