The protozoan pathogen Perkinsus marinus is the causative agent of Dermo, a lethal disease of the eastern oyster Crassostrea virginica, but not the Pacific oyster Crassostrea gigas. [...] Key Result The number of differentially expressed gene sequences obtained was 107 for C. virginica and 69 for C. gigas, including 46 and 37 sequences, respectively, that matched known genes in GenBank. Most of the sequences have not been characterized in other molluscs.Expand
Microarray analysis of gene expression in eastern oyster (Crassostrea virginica) reveals a novel combination of antimicrobial and oxidative stress host responses after dermo (Perkinsus marinus) challenge.
Dermo disease, caused by Perkinsus marinus, is one of the most severe diseases of eastern oysters, Crassostrea virginica. It causes serious mortalities in both wild and aquacultured oysters. UsingExpand

Host Response when Perkinsus marinus Infection Intensities Increase in the Oyster Crassostrea corteziensis
ABSTRACT The protozoan Perkinsus marinus was identified for the first time in the oyster Crassostrea corteziensis from the state of Baja California Sur, Mexico. Intensities of P. marinus infectionsExpand
Characterizing the Epigenetic and Transcriptomic Responses to Perkinsus marinus Infection in the Eastern Oyster Crassostrea virginica
Eastern oysters in the northern Gulf of Mexico are routinely infected with the protistan parasite Perkinsus marinus, the cause of the disease commonly known as dermo. Recent experimental challengesExpand
Molecular identification and expression study of differentially regulated genes in the Pacific oyster Crassostrea gigas in response to pesticide exposure
The effects of pesticide contamination on the metabolism of marine molluscs are poorly documented. We investigated the response of a marine bivalve, the Pacific oyster, Crassostrea gigas, using aExpand

Susceptibility Of Diploid And Triploid Pacific Oysters, Crassostrea Gigas (Thunberg, 1793) And Eastern Oysters, Crassostrea virginica (Gmelin, 1791), To Perkinsus marinus
TLDR
Pacific oysters, Crassostrea gigas, was consistently more tolerant of P. marinus than was C. virginica, and triploidy provided no increased disease tolerance for either species. Expand
Immune gene discovery by expressed sequence tags generated from hemocytes of the bacteria-challenged oyster, Crassostrea gigas.
TLDR
An expressed sequence tag program to isolate genes involved in defense mechanisms of the Pacific oyster, Crassostrea gigas, identified 20 genes that may be implicated in immune function and investigated the expression of four of them during bacterial challenge of oysters. Expand
Potential Indicators of Stress Response Identified by Expressed Sequence Tag Analysis of Hemocytes and Embryos from the American Oyster, Crassostrea virginica
TLDR
Diversity analysis shows that 363 and 286 unique genes were identified from the hemocyte and embryo libraries, respectively, indicating that full-scale EST collection is a valuable approach for the discovery of new genes of potential significance in the molluscan stress response. Expand
Haemocytic and humoral activities of eastern and Pacific oysters following challenge by the protozoan Perkinsus marinus
TLDR
The data suggest that Pacific oysters may offer a less favourable environment for the development of P. marinus as compared to eastern oysters for at least two possible reasons; i.e. the elevated cellular and humoral activities may degrade the parasite more effectively, and/or the lower plasma protein levels may limit parasite growth. Expand
Epizootiology of Perkinsus marinus disease of oysters in Chesapeake Bay, with emphasis on data since 1985
TLDR
Long-term oyster disease monitoring along a salinity gradient in the James River revealed a statistically significant relationship between salinity and P. marinus prevalence and intensity, which is clearly correlated with salinity increases resulting from drought conditions in the late 1980s. Expand
Comparison of in vitro-cultured and wild-type Perkinsus marinus. I. Pathogen virulence.
TLDR
It is demonstrated that parasites freshly isolated from infected hosts are much more virulent than those propagated in culture, indicating a potential deficiency in the culture medium used. Expand
The Lipopolysaccharide and β-1,3-Glucan Binding Protein Gene Is Upregulated in White Spot Virus-Infected Shrimp (Penaeus stylirostris)
TLDR
The data suggest that shrimp LGBP is an inducible acute-phase protein that may play a critical role in shrimp-WSV interaction and that the WSV infection regulates the activation and/or activity of the proPO cascade in a novel way. Expand
Inhibition of in vitro replication of the oyster parasite Perkinsus marinus by the natural iron chelators transferrin, lactoferrin, and desferrioxamine.
TLDR
The results indicate that the oyster parasite has a strong requirement for soluble iron and its growth rates are correlated with iron availability, and it is proposed that excess iron accumulation in the host Crassostrea virginica promotes parasite proliferation. Expand

Pernin: a novel, self-aggregating haemolymph protein from the New Zealand green-lipped mussel, Perna canaliculus (Bivalvia: Mytilidae).
TLDR
A protein, designated pernin, found in the New Zealand green-lipped mussel, comprises almost all of the protein in cell-free haemolymph, and has sequences clearly homologous to the active-site domain of Cu-Zn SODs (superoxide dismutases). Expand
