Transfection of the protozoan parasite Perkinsus marinus

Molecular and Biochemical Parasitology, 2008
Ongoing efforts for sequencing the genome of the protozoan parasite Perkinsus marinus, together with functional genomic initiatives, have continued to provide invaluable information about genes and metabolic pathways that not only will increase our understanding of its biology, but also have the potential to reveal useful targets for intervention.

Monoclonal antibody analysis of Perkinsus marinus extracellular products

International Journal for Parasitology, 2005
The protozoan oyster parasite Perkinsus marinus releases a complex set of extracellular products (ECP) during in vitro culture. These products have been previously implicated in parasite virulence, and their expression can be altered by medium supplementation with oyster tissue homogenate.

Phospholipid biosynthesis in the oyster protozoan parasite, Perkinsus marinus

Molecular and Biochemical Parasitology, 2002
Perkinsus marinus is a protozoan parasite that causes high mortality in its commercially and ecologically important host, the Eastern oyster Crassostrea virginica. In order to understand the host-parasite relationship in lipid metabolism, the ability of P. marinus to synthesize phospholipids from polar headgroup precursors was investigated. Pulse/chase

Signal Recognition Particle RNA in Dinoflagellates and the Perkinsid Perkinsus marinus

Protist, 2013
In dinoflagellates and perkinsids, the molecular structure of the protein translocating machinery is unclear. Here, we identified several types of full-length signal recognition particle (SRP) RNA genes from Karenia brevis (dinoflagellate) and Perkinsus marinus (perkinsid).

Lethal effects of silver nanoparticles on Perkinsus marinus, a protozoan oyster parasite

Journal of Invertebrate Pathology, 2020
Perkinsus marinus, a World Organisation for Animal Health (OIE) notifiable parasite, infects several species of oyster, including Crassostrea virginica and Crassostrea corteziensis. There is little information on possible treatments for this parasite, but the biocidal properties of silver nanoparticles (AgNP) suggest their potential use.

Distribution of Perkinsus marinus in Gulf Coast Oyster Populations

Estuaries, 1989
Prevalence (percent of oysters infected) ofPerkinsus marinus and infection intensity were measured in oysters from 49 sites in the Gulf of Mexico. Prevalence was less than 50% at only one site. Both prevalence and infection intensity were correlated with condition index, salinity, and a measure of local agricultural activity.

Identification of Two Spliced Leader RNA Transcripts from Perkinsus marinus

Journal of Eukaryotic Microbiology, 2011
Spliced leader (SL) variants are present in a number of mRNAs from Perkinsus marinus. Three different SLs of 22 nucleotides (nt) in length were previously reported, with a consensus sequence of (DCCGUAGCCAUYUUGGCUCAAG). A truncated 21 nt SL, with an (A) at nt-1 and a (U) deletion at nt-13, has also been reported.

Near infrared reflectance spectroscopy to quantify Perkinsus marinus infecting Crassostrea virginica

Aquaculture, 2021
Abstract Disease caused by the protozoan parasite Perkinsus marinus remains a challenge for fisheries and aquaculture of the eastern oyster, Crassostrea virginica. Near infrared reflectance (NIR) spectroscopy is a technology that allows measurements of multiple biochemical components at the same time, providing extensive information for every tested ...

Do scavengers influence dermo disease (Perkinsus marinus) transmission?

2012
Perkinsus marinus is the protozoan endoparasite of the Eastern oyster (Crassostrea virginica) responsible for Dermo disease. While not harmful to humans, Dermo disease causes extensive oyster mortality, increasing annual natural mortality from 10 to 35% or more in Delaware Bay annually. The disease spreads through the water as parasites are shed from

TAQMAN® MGB REAL-TIME PCR APPROACH TO QUANTIFICATION OF PERKINSUS MARINUS AND PERKINSUS SPP. IN OYSTERS

Journal of Shellfish Research, 2006
Abstract Several molecular diagnostic assays have been developed in an attempt to replace the traditional Ray's Fluid Thioglycollate Medium (RFTM) assay for detection and quantification of Perkinsus marinus in oysters. Real-time PCR technology is a state-of-the-art method currently used to diagnose disease intensity in vertebrates.
