Virus-like particles associated with mortalities of the Manila clam Ruditapes philippinarum in England.

چکیده
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 unenveloped virus-like particles within the connective tissue of the gills and surrounding the tubules in the digestive gland. The virus-like particles appeared to be free within the cytoplasm or associated with endoplasmic reticulum membranes and cytoplasmic vesicles. Particles were icosahedral in shape, with a diameter of 25 to 30 nm. The location, size and morphology of the virus-like particles suggest that they belong to the Picornaviridae family. This is the first report of this virus infection in wild and farmed R. philippinarum within the UK.

Virus-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 کاملEcophysiology of Brown Ring Disease in the Manila clam Ruditapes philippinarum, experimental and modelling approaches
Brown Ring Disease (BRD) in the Manila clam, Ruditapes philippinarum, is a disease caused by the bacterium Vibrio tapetis. This pathology was first observed in Northern Brittany (France) in 1987. The pathogenic agent enters in the extrapallial cavity (i.e. the space between mantle and shell), disrupts the normal production of periostracal lamina and causes an anomalous deposition of periostracu...

Manila clam Ruditapes philippinarum is one of the most important economic species in shellfishery in China due to its wide geographic distribution and high tolerance to environmental changes (e.g., salinity, temperature). In addition, Manila clam is a good biomonitor/bioindicator in "Mussel Watch Programs" and marine environmental toxicology. However, there are several pedigrees of R. philippin...
متن کاملPathogenicity of Vibrio tapetis, the etiological agent of brown ring disease in clams.
Brown ring disease (BRD) causes high mortalities in the introduced Manila clam Ruditapes philippinarum cultured in western Europe. The etiological agent of BRD, Vibrio tapetis, adheres to and disrupts the production of the periostracal lamina, causing the anomalous deposition of periostracum around the inner shell. Because the primary sign of BRD is found outside the soft tissues, the processes...
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...
