| 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 |
| production of transgenic dwarf surfclams, mulinia lateralis, with pantropic retroviral vectors. | a pantropic pseudotyped retroviral vector containing the envelope protein of vesicular stomatitis virus was used as a gene transfer vector in the dwarf surfclam, mulinia lateralis. these pantropic retroviral vectors have an extremely broad host cell range and can infect many nonmammalian species. newly fertilized dwarf surfclam eggs were electroporated at 700 v in the presence of 1 x 10(4) colony-forming units of pantropic pseudotyped retroviral particles. infection was well tolerated and did no ... | 1996 | 8622962 |
| mulinia lateralis (mollusca: bivalvia) die-off in south carolina: discovery of a vector for two elasmobranch cestode species. | unexplained and episodic die-offs of the dwarf surf clam, mulinia lateralis , have been reported on the west atlantic coast, with such an occurrence in south carolina in june 2010. a sample of live clams from the 2010 south carolina event was collected, and 200 clams were measured and necropsied. two species of tapeworm larvae were observed. plerocercoids (duplicibothrium sp.) occupied the digestive gland ducts, and merocercoids (rhodobothrium sp.) were found beneath the mantle. specimens of bot ... | 2013 | 22924916 |
| composition, shell strength, and metabolizable energy of mulinia lateralis and ischadium recurvum as food for wintering surf scoters (melanitta perspicillata). | decline in surf scoter (melanitta perspicillata) waterfowl populations wintering in the chesapeake bay has been associated with changes in the availability of benthic bivalves. the bay has become more eutrophic, causing changes in the benthos available to surf scoters. the subsequent decline in oyster beds (crassostrea virginica) has reduced the hard substrate needed by the hooked mussel (ischadium recurvum), one of the primary prey items for surf scoters, causing the surf scoter to switch to a ... | 2015 | 25978636 |
