First characterization of the parasite Haplosporidium costale in France and development of a real‐time PCR assay for its rapid detection in the Pacific oyster, Crassostrea gigas

Transboundary and Emerging Diseases, Volume 69, Issue 5, Page e2041-e2058, September 2022., 2022
Abstract The Pacific cupped oyster Crassostrea gigas is one of the most ‘globalized’ marine invertebrates and its production is predominant in many parts of the world including Europe. However, it is threatened by mortality events associated with pathogenic microorganisms such as the virus OsHV‐1 and the bacteria Vibrio aestuarianus. C. gigas is also a

Assessment of Infection Prevalence and Intensity of Disease-Causing Parasitic Protozoans Perkinsus marinus and Haplosporidium nelsoni in Georgia Oysters

Microorganisms, 2023
Eastern oysters, Crassostrea virginica, are ecologically and economically important coastal species which provide a commercially valuable food product while also improving water quality through filtration, protecting shorelines, and providing habitat ...

CRISPR/Cas9‐induced disruption of Bodo saltans paraflagellar rod‐2 gene reveals its importance for cell survival

Environmental Microbiology, Volume 24, Issue 7, Page 3051-3062, July 2022., 2022
Summary Developing transfection protocols for marine protists is an emerging field that will allow the functional characterization of protist genes and their roles in organism responses to the environment. We developed a CRISPR/Cas9 editing protocol for Bodo saltans, a free‐living kinetoplastid with tolerance to both marine and freshwater conditions ...

Don't move a mussel? Parasite and disease risk in conservation action

Conservation Letters, Volume 14, Issue 4, July/August 2021., 2021
Abstract Freshwater mussels are one of the most endangered animal groups globally, making them a high conservation priority. Conservationists increasingly employ translocation or captive breeding procedures to support ailing populations, and the ecosystem engineering capabilities of mussels are being increasingly harnessed in bioremediation projects ...

A rapid phenotype change in the pathogen Perkinsus marinus was associated with a historically significant marine disease emergence in the eastern oyster

Scientific Reports, 2021
The protozoan parasite Perkinsus marinus, which causes dermo disease in Crassostrea virginica, is one of the most ecologically important and economically destructive marine pathogens.

Context‐dependent carryover effects of hypoxia and warming in a coastal ecosystem engineer

Ecological Applications, Volume 31, Issue 4, June 2021., 2021
Abstract Organisms are increasingly likely to be exposed to multiple stressors repeatedly across ontogeny as climate change and other anthropogenic stressors intensify. Early life stages can be particularly sensitive to environmental stress, such that experiences early in life can “carry over” to have long‐term effects on organism fitness.

Isolation and characterization of serine protease gene(s) from Perkinsus marinus [PDF]

Diseases of Aquatic Organisms, 2003
This study reports the first serine protease gene(s) isolated from Perkinsus marinus. Using universal primers, a 518 bp subtilisin-like serine protease gene fragment was amplified from P. marinus genomic DNA and used as a probe to screen a lambda-phage P.

Perkinsus marinus in bioreactor: growth and a cost-reduced growth medium

Journal of Industrial Microbiology and Biotechnology, 2023
Abstract   Perkinsus marinus (Perkinsea) is an osmotrophic facultative intracellular marine protozoan responsible for “Dermo” disease in the eastern oyster, Crassostrea virginica. In 1993 in vitro culture of P. marinus was developed in the absence of host cells.

Partial inhibition of hemocyte agglutination by Lathyrus odoratus lectin in Crassotrea virginica infected with Perkinsus marinus

Memorias do Instituto Oswaldo Cruz, 1995
Quantitative determinations of agglutination of hemocytes from oysters, Crassostrea virginica, by the Lathyrus odoratus lectin at five concentrations revealed that clumping of hemocytes from oysters infected with Perkinsus marinus is partially inhibited.

Epizootiology of Perkinsus sp. inCrassostrea gasar oysters in polyculture with shrimps in northeastern Brazil

Revista Brasileira de Parasitologia Veterinária, 2016
Bivalve culture is of considerable economic and social interest in northeastern (NE) Brazil. The polyculture is an alternative approach to traditional monoculture for reducing the environmental impact of shrimp farming and improving oyster culture ...
