ABSTRACT: 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.
