Performance of oysters selected for dermo resistance compared to wild oysters in northern Gulf of Mexico estuaries

Aquaculture Environment Interactions, 2017
The performance of the progeny of eastern oysters Crassostrea virginica from Louisiana selected for resistance to dermo, caused by Perkinsus marinus (referred to as ‘OBOY’) and of wild oysters collected from Louisiana (Calcasieu Lake) and Alabama (Cedar ...

The protistan parasite Perkinsus marinus is resistant to selected reactive oxygen species [PDF]

Experimental Parasitology, 2003
The parasite Perkinsus marinus has devastated natural and farmed oyster populations along the Atlantic and Gulf coasts of North America. When viable P. marinus trophozoites are engulfed by oyster hemocytes, the typical accumulation of reactive oxygen species (ROS) normally associated with phagocyte activity is not observed.

Successful eastern oyster (Crassostrea virginica) recruitment on intertidal artificial substrates in Virginia, USA

Ecosphere, Volume 16, Issue 8, August 2025.
Abstract Declines of eastern oyster (Crassostrea virginica) populations and scarcity of natural oyster shell necessitate quantifying the effectiveness of artificial oyster reef substrates over varying environmental conditions. Oyster castles are often used in intertidal areas with moderate wave energy; however, new concrete, natural‐looking substrates,

Description of two species of early branching dinoflagellates, Psammosa pacifica n. g., n. sp. and P. atlantica n. sp. [PDF]

PLoS ONE, 2012
In alveolate evolution, dinoflagellates have developed many unique features, including the cell that has epicone and hypocone, the undulating transverse flagellum. However, it remains unclear how these features evolved.

Integrating climate change, biological invasions, and infectious wildlife diseases

Frontiers in Ecology and the Environment, Volume 23, Issue 6, August 2025.
Climate change is likely to affect infectious diseases that are facilitated by biological invasions, with repercussions for wildlife conservation and zoonotic risks. Current invasion management and policy are underprepared for the future risks associated with such invasion‐related wildlife diseases. By considering evidence from bioclimatology, invasion

A highly sensitive and specific real-time quantitative polymerase chain reaction assay for Perkinsus marinus detection in oysters

Scientific Reports
Oyster aquaculture is one of the fastest-growing food production industries worldwide; however, it faces a significant challenge from the protist Perkinsus marinus, particularly in the USA. Although several quantitative molecular diagnostic methodologies

Bivalve microbiomes are shaped by host species, size, parasite infection, and environment [PDF]

PeerJ
Many factors affect an organism’s microbiome including its environment, proximity to other organisms, and physiological condition. As filter feeders, bivalves have highly plastic microbiomes that are especially influenced by the surrounding seawater, yet

Non‐Random Mortality in an Experimental Oyster Restoration

Evolutionary Applications, Volume 18, Issue 7, July 2025.
ABSTRACT Ecological restoration has emerged as a prominent conservation and management strategy widely touted for its utility in evaluating ecological theories when designed experimentally. In comparison, restoration has been underutilized to investigate evolution‐oriented questions, despite the importance of evolutionary processes in conservation and ...

Characterizing the Epigenetic and Transcriptomic Responses to Perkinsus marinus Infection in the Eastern Oyster Crassostrea virginica

Frontiers in Marine Science, 2020
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.

Drug selection strategy for transfected Perkinsus marinus cells v1

, 2020
We use the previously published protocol https://dx.doi.org/10.17504/protocols.io.gv9bw96 to electroporate Perkinsus marinus cells with plasmids described in the protocol https://dx.doi.org/10.17504/protocols.io.37egrje We have developed a drug selection strategy for rapid generation of cells expressing introduced transgenes.
