Comparison of in vitro-cultured and wild-type Perkinsus marinus. I. Pathogen virulence [PDF]

Diseases of Aquatic Organisms, 2002
Perkinsus marinus is a highly contagious pathogen of the eastern oyster Crassostrea virginica. Until recently, transmission studies have employed wild-type parasites isolated directly from infected oysters. Newly developed methods to propagate P. marinus in vitro have led to using cultured parasites for infection studies, but results suggest that ...

Expanding the phylogeography and connectivity of Perkinsus species across North and Central America

Diversity and Distributions, Volume 30, Issue 3, March 2024.
Abstract Aim Parasites in the genus Perkinsus infect marine molluscs globally, with novel detections expanding and reshaping our knowledge of their biogeographic patterns and the factors influencing those patterns. Here, we aimed to characterize the phylogeography and genetic connectivity of Perkinsus spp.

Large‐scale eDNA monitoring of multiple aquatic pathogens as a tool to provide risk maps for wildlife diseases

Environmental DNA, Volume 6, Issue 1, January–February 2024.
Environmental DNA techniques can be applied for the simultaneous detection of multiple aquatic wildlife pathogen species. In this study we conducted an eDNA‐based survey monitoring several pathogens of concern in Switzerland. We identify advantages and limitations of eDNA‐based pathogen monitoring versus more conventional methods.

Drivers of Perkinsus marinus and Haplosporidium nelsoni prevalence and intensity in oyster reefs around Sapelo Island, Georgia

Parasitology
Parasites can strongly influence host populations, particularly when the host is an ecosystem engineer. Oysters are ecosystem engineers that support estuarine communities and fisheries but are susceptible to 2 protozoan parasites, Perkinsus marinus ...

A restoration suitability index model for the eastern oyster (Crassostrea virginica) in the Mission-Aransas Estuary, TX, USA.

PLoS ONE, 2012
Oyster reefs are one of the most threatened marine habitats on earth, with habitat loss resulting from water quality degradation, coastal development, destructive fishing practices, overfishing, and storm impacts.

Co-phylogeographic structure in a disease-causing parasite and its oyster host

Parasitology
With the increasing affordability of next-generation sequencing technologies, genotype-by-sequencing has become a cost-effective tool for ecologists and conservation biologists to describe a species' evolutionary history.

Comparative Time-Scale Gene Expression Analysis Highlights the Infection Processes of Two Amoebophrya Strains

Frontiers in Microbiology, 2018
Understanding factors that generate, maintain, and constrain host-parasite associations is of major interest to biologists. Although little studied, many extremely virulent micro-eukaryotic parasites infecting microalgae have been reported in the marine ...

SEASONAL VARIATION OF Perkinsus marinus IN THE AMERICAN OYSTER Crassostrea virginica FROM THE CARMEN-MACHONA PAJONAL LAGOON SYSTEM IN TABASCO, MEXICO

Tropical and Subtropical Agroecosystems, 2012
In the Gulf of Mexico, the fishery of the oyster Crassostrea virginica is the main resource for you capture volume (42, 796 t). This resource is affected by the disease of the Dermo, which has been little studied in the Gulf of Mexico.

Occurrence and Seasonality of Perkinsus marinus (Protozoa: Apicomplexa) in Mississippi Oysters

Gulf Research Reports, 1980
Oysters from four reefs in Mississippi Sound, sampled over a period of 25 months, were found to have a low prevalence of the protozoan parasite Perkinsus marinus. The greatest values were 80% prevalence, and 0.88 weighted incidence recorded for oysters from Biloxi Bay, Mississippi.

Golden Gate plasmids used for transfection of Perkinsus marinus v1 [PDF]

, 2019
We have created plasmids for transfection of the parasite Perkinsus marinus using Golden Gate cloning. We have explored the possibility to either FACS sort (GFP/mCherry fused to MOE membrane protein) or using drug selection (bleomycin, blasticidin S or puromycin) to enrich transfected cells.
