Genetic signature analysis of Perkinsus marinus in Mexico suggests possible translocation from the Atlantic Ocean to the Pacific coast of Mexico

Parasites & Vectors, 2017
Background The protozoan Perkinsus marinus (Mackin, Owen & Collier) Levine, 1978 causes perkinsosis in the American oyster Crassostrea virginica Gmelin, 1791. This pathogen is present in cultured C. virginica from the Gulf of Mexico and has been reported

Humanized HLA-DR4 mice fed with the protozoan pathogen of oysters Perkinsus marinus (Dermo) do not develop noticeable pathology but elicit systemic immunity.

PLoS ONE, 2014
Perkinsus marinus (Phylum Perkinsozoa) is a marine protozoan parasite responsible for "Dermo" disease in oysters, which has caused extensive damage to the shellfish industry and estuarine environment.

Environmental factors drive the release of Perkinsus marinus from infected oysters [PDF]

Parasitology, 2020
Abstract Since the discovery of Perkinsus marinus as the cause of dermo disease in Crassostrea virginica , salinity and temperature have been identified as the main environmental drivers of parasite prevalence. However, little is known

Intensive oyster aquaculture can reduce disease impacts on sympatric wild oysters

Aquaculture Environment Interactions, 2018
Risks associated with disease spread from fish and shellfish farming have plagued the growth and public perception of aquaculture worldwide. However, by processing nutrients and organic material from the water column, the culture of many suspension ...

Responses of an oyster host (Crassostrea virginica) and its protozoan parasite (Perkinsus marinus) to increasing air temperature [PDF]

PeerJ, 2018
Background Changes in climate are predicted to influence parasite and pathogen infection patterns in terrestrial and marine environments. Increases in temperature in particular may greatly alter biological processes, such as host-parasite interactions ...

Energetic budget of diploid and triploid eastern oysters during a summer die-off

Frontiers in Marine Science, 2023
Triploid oysters are widely used in off-bottom aquaculture of eastern oysters, Crassostrea virginica. However, farmers of the Gulf of Mexico (GoM) and Atlantic coast estuaries have observed unresolved, late-spring die-offs of triploid oysters ...

Lacking catalase, a protistan parasite draws on its photosynthetic ancestry to complete an antioxidant repertoire with ascorbate peroxidase

BMC Evolutionary Biology, 2019
Background Antioxidative enzymes contribute to a parasite’s ability to counteract the host’s intracellular killing mechanisms. The facultative intracellular oyster parasite, Perkinsus marinus, a sister taxon to dinoflagellates and apicomplexans, is ...
