| immunocytochemical localization of a calcium-binding phosphoprotein in hemocytes of heterodont bivalves. | calcium-binding phosphoprotein particles are the most abundant extracellular proteins in the hemolymph of heterodont bivalves, and granular hemocytes are the most abundant cells in the same fluid. in this study, the hemocytes of rangia cuneata were examined ultrastructurally and probed with anti-phosphoprotein igg to demonstrate that the granulocytes are a probable source of the hemolymph phosphoprotein. the granulocyte cytoplasm is laden with large vesicles containing an amorphous homogenous ma ... | 1990 | 2181053 |
| molecular epizootiology of perkinsus marinus and p. chesapeaki infections among wild oysters and clams in chesapeake bay, usa. | perkinsus marinus and p. chesapeaki host ranges among wild chesapeake bay, usa, region bivalves were examined by surveying crassostrea virginica oysters and members of several sympatric clam species from 11 locations. perkinsus genus- and species-specific pcr assays were performed on dna samples from 731 molluscs, and species-specific in situ hybridization assays were performed on a selected subset of histological samples whose pcr results indicated dual or atypical perkinsus sp. infections. pcr ... | 2008 | 19244976 |
| elapid alpha-toxins have no effect on the cholinergic responses of bivalve myocardia. | elapid alpha-toxins (alpha-bungarotoxin, alpha-cobratoxin and crude bungarus caeruleus venom) do not affect the myocardial nicotinic ach receptors of the following bivalve molluscs: mercenaria mercenaria, chione cancellata, mya arenaria, mytilus edulis, rangia cuneata and crassostrea virginica. | 1978 | 729727 |
| edna and specific primers for early detection of invasive species--a case study on the bivalve rangia cuneata, currently spreading in europe. | intense human activities facilitate the successful spread and establishment of non-indigenous aquatic organisms in marine and freshwater ecosystems. in some cases such intrusions result in noticeable and adverse changes in the recipient environments. in the baltic sea, the discovery and rapid initial spread of the north american wedge clam rangia cuneata represents a new wave of invasion which may trigger unpredictable changes of the local benthic communities. in this study we present a species- ... | 2015 | 26453004 |
| a diagnostic molecular marker for zebra mussels (dreissena polymorpha) and potentially co-occurring bivalves: mitochondrial coi. | we report diagnostic differences in the nucleotide sequences of a 710-bp fragment of the mitochondrial cytochrome c oxidase subunit i gene (coi) from the zebra mussel (dreissena polymorpha) and potentially co-occurring bivalves: the quagga mussel (dreissena bugensis); the asiatic clam (corbicula fluminea), the dark false mussel (mytilopsis leucophaeata), and the wedge clam (rangia cuneata). the coi sequence of the deep-water "profunda" phenotype of the quagga mussel was nearly identical to that ... | 1996 | 8869514 |
