Virus-like particles associated with mortalities of the Manila clam Ruditapes philippinarum in England.
Mortalities of the Manila clam Ruditapes philippinarum (Adams & Reeve, 1850) were reported in southern England (Kent and Poole Harbour) during late spring of 2008. In response to these reported mortalities, samples were collected from 5 sites across the south coast of England. Clams were sampled for both histology and electron microscopy. Transmission electron microscopy (TEM) revealed unenvelo...
متن کاملVirus-like particles associated with brown muscle disease in Manila clam, Ruditapes philippinarum, in Arcachon Bay (France).
Recently, Manila clam, Ruditapes philippinarum, populations have suffered mortalities in Arcachon Bay (SW France). Mortality was associated with extensive lesions of the posterior adductor muscle, which become progressively brown and calcified. Ultrastructural observations by transmission electron microscopy revealed tissue degradation with necrotized muscle fibres and granulocytomas. Unenvelop...
متن کاملVirus-like particles associated with mortalities of the carpet-shell clam Ruditapes decussatus.
During the late summer and early fall of 1997 and 1998 heavy mortalities were detected in the carpet-shell clam Ruditapes decussatus cultured in Galicia (NW Spain). The prevalences and intensities of the parasites found in the histopathological studies were not high enough to explain the high mortality rates. Unenveloped virus-like particles were detected by transmission electron microscopy in ...
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 ...
متن کاملHemocytes of the carpet shell clam ( Ruditapes decussatus) and the Manila clam (Ruditapes philippinarum): Current knowledge and future prospects
Hemocytes are the immune effectors in clams, directing cellular but also humoral defences. In the Manila clam (Ruditapes philippinarum) and the carpet shell clam (Ruditapes decussatus), two phenotypically similar venerid species, fishery and aquaculture importance motivated scientific studies to improve knowledge about the participation of hemocytes in immune response. Currently, gaps still per...
