Description of Perkinsus andrewsi n. sp. Isolated from the Baltic Clam (Macoma balthica) by Characterization of the Ribosomal RNA Locus, and Development of a Species-Specific PCR-Based Diagnostic Assay
Abstract A Perkinsus species was isolated from the baltic clam Macoma balthica and an in vitro culture established under conditions described for P. marinus. As reported previously, morphologicalExpand
Parasitism by the protozoan Perkinsus atlanticus favours the development of opportunistic infections.
These findings show that P. atlanticus parasitism favours the development of opportunistic infections which have detrimental effects in this clam population. Expand
Ultrastructural Characteristics of the In Vitro Cell Cycle of the Protozoan Pathogen of Oysters, Perkinsus marinus
Ulastructural characteristics of the vegetative and zoosporangial stages of cultured Perkinsus marinus, a pathogen of the eastern oyster, did not resemble any apicomplexan parasites other than members of the genus Perkinsus. Expand
Water-borne transmission of Dermocystidium
  • 2006
Dermocystidjum salmonis is a gill pathogen of salmonid fishes in the U.S. Pacific Northwest where it has been associated with mortality of adult and juvenile chinook salmon Oncorhynchus tshawytscha.Expand
Aquatic Living Resources Perkinsosis in molluscs : A review
The genus Perkinsus includes protistan parasites infecting marine molluscs throughout the world, some of which are associated with mass mortalities. Life cycle involves vegetative proliferationExpand
Sequence of the Small Subunit Ribosomal RNA Gene of Perkinsus atlanticus-like Isolated from Carpet Shell Clam in Galicia, Spain
The phylogenetic analysis of the cultured parasite led to the conclusion that this isolate is not related to the genus Perkinsus but to the protists Anurofeca, Ichthyophonus, and Psorospermium, located near the animal-fungal divergence. Expand
New Perkinsea Parasitoids of Dinoflagellates Distantly Related to Parviluciferaceae Members
The findings from this study suggest that Perkinsea representatives infecting dinoflagellates are more widespread than previously thought. Expand
Parvilucifera multicavata sp. nov. (Alveolata, Perkinsozoa), a New Parasitoid Infecting Marine Dinoflagellates Having Abundant Apertures on the Sporangium.
Morphological and ultrastructural observations revealed that the new parasitoid shares almost all known diagnostic characters with other species of Parvilucifera, except that its sporangium has a higher number of apertures although with smaller diameters than those in P. infectans. Expand
Prevalence, diagnosis and experimental challenge of Dermocystidium sp. infection in Nile tilapia (Oreochromis niloticus) in Egypt
Abstract This study confirms the systemic position of Dermocystidium sp. in Nile tilapia (Oreochromis niloticus) internal organs (liver, spleen, kidneys, stomach and intestine). Our work reveals anExpand
