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 کاملMolecular evolution and recombination in gender-associated mitochondrial DNAs of the Manila clam Tapes philippinarum.
Doubly uniparental inheritance (DUI) provides an intriguing system for addressing aspects of molecular evolution and intermolecular recombination of mitochondrial DNA. For this reason, a large sequence analysis has been performed on Tapes philippinarum (Bivalvia, Veneridae), which has mitochondrial DNA heteroplasmy that is consistent with a DUI. The sequences of a 9.2-kb region (containing 29 g...
متن کاملIsolation and characterization of a pathogenic bacterium specific to Manila clam Tapes philippinarum larvae
A bactenal straln belonging to the genus Vibno was involved in a recurrent outbreak of disease In Manila clam Tapes phdipplnaruni larvae at a commercial hatchery. This vibrio, named VTP for convenience, was not related to the known pathogenic vibrios and possessed unusual characteristics. Only Manila clam larvae and postlarvae were affected by the disease. Oyster and scallop larvae were not aff...
متن کاملDevelopment of real-time PCR assays for discrimination and quantification of two Perkinsus spp. in the Manila clam Ruditapes philippinarum.
The Manila clam Ruditapes philippinarum is infected with 2 Perkinsus species, Perkinsus olseni and P. honshuensis, in Japan. The latter was described as a new species in Mie Prefecture, Japan, in 2006. Ray's Fluid Thioglycollate Medium (RFTM) assay has been most commonly used to quantify Perkinsus infection. However, this assay cannot discriminate between species that resemble one another morph...
متن کاملDispersal, recurrence and settlement of Manila clam, Ruditapes philippinarum
The majority of the marine benthos is pelagic in their larval stage. The Manila clam Ruditapes philippinarum, is widely distributed on sandy tidal flats across Japan and a commercially important shellfish. The clam has a planktonic larval stage, which lasts 2 to 3 weeks after hatching. In this stage, the most clam larvae are able to disperse over wide areas with the currents and then settle on ...
