| perkinsus 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 from each site at each collection time. samples were separately diagnosed for p. marinus infections by ... | 1998 | 9789979 |
| nucleotide sequence variability in the nontranscribed spacer of the rrna locus in the oyster parasite perkinsus marinus. | we examined the sequence variability of the nontranscribed spacer (nts) and internal-transcribed spacer (its1 and its2) domains of the rrna locus of perkinsus marinus from maryland, florida, and louisiana. the sequence of p. marinus dna including the 5s rrna, nts, small subunit (ssu) rrna, itsi, and its2 regions confirmed their contiguity in the rrna locus and revealed differences at 28 positions with the ssu rrna sequences published earlier. the 307-bp polymerase chain reaction (pcr)-amplified ... | 1999 | 10461944 |
