Occurrence of Perkinsus species (Protozoa, Apicomplexa) in bivalves from the Great Barrier
Bivalves from the Great Barrier Reef were examined for Perkinsus infection using the thioglycollate method (Ray 1966). They were taken from Heron, Lizard, Orpheus, North Direction and Thetford Reefs. Thirty of the 84 species examined were Infected (160 out of 644 individuals). They belonged to 23 families. The 4 most frequently infected families, in descending order, were Chamidae, Arcidae, Tri...
متن کاملDiscovery of genes expressed in response to Perkinsus marinus challenge in Eastern (Crassostrea virginica) and Pacific (C. gigas) oysters.
The protozoan pathogen Perkinsus marinus is the causative agent of Dermo, a lethal disease of the eastern oyster Crassostrea virginica, but not the Pacific oyster Crassostrea gigas. To understand the response of these two oysters to parasite exposure, a suppression subtractive hybridization (SSH) method was employed to characterize genes up-regulated during parasite challenge in both hemocytes ...
متن کاملThe Relationship Between Increasing Sea-surface Temperature and the Northward Spread of Perkinsus marinus (Dermo) Disease Epizootics in Oysters
From its initial discovery in the Gulf of Mexico in the late 1940s until 1990, Perkinsus marinus, the parasite responsible for Dermo disease in the eastern oyster, Crassostrea virginica, was rarely found north of Chesapeake Bay. In 1990–92, an apparent range extension of the parasite led to epizootic outbreaks of the disease over a 500 km range north of Chesapeake Bay. One of the hypotheses for...
متن کاملPerkinsus marinus tissue distribution and seasonal variation in oysters Crassostrea virginica from Florida, Virginia and New York.
Perkinsus marinus infection intensity was measured in eastern oysters Crassostrea virginica collected in October and December 1993, and March, May, and July 1994 from 3 U.S. sites: Apalachicola Bay (FL), Chesapeake Bay (VA), and Oyster Bay (NY). Gill, mantle, digestive gland, adductor muscle, hemolymph, and remaining tissue (including gonadal material and rectum) were dissected from 20 oysters ...
متن کاملPerkinsus beihaiensis (Perkinsozoa) in oysters of Bahia State, Brazil.
This study reports the pathogen Perkinsus beihaiensis in oysters of the genus Crassostrea on the coast of the State of Bahia (Brazil), its prevalence, infection intensity and correlation with salinity. Oysters (n = 240) were collected between October and December 2014 at eight sampling stations between latitudes 13°55'S and 15°42'S. The laboratory procedures included macroscopic analysis, histo...
