| Little information is available on viral infections that affect bivalve molluscs. Such a lack of data is due ta a certain inadequacy of the diagnosis methods that are employed when massive mortality events occur. Most laboratories involved in mollusc pathology still analyse samples through light microscopy. World-wide, there is thus currently a lack of information concerning the occurrence of bivalve herpesvituses. This is probably due to the lack of suitable diagnostic tools. The basic method for identification and examination of suspect samples is predominantly histopathology. This enables the identification of any cellular changes, but is not conclusive identification of bivalve herpesviruses. This technique doesn't allow, by itself, to detect viruses... |

| Since 1991, numerous herpesvirus infections associated with high mortality have been reported around the world in various marine bivalve species. In order to determine whether these infections are due to ostreid herpesvirus-l (OsHV1), a previously characterized pathogen of the Japanese oyster (Crassostrea gigas), PCR analysis was carried out on 30 samples of larvae collected from four bivalve species (C. gigas, Ostrea edulis, Ruditapes decussatus and Ruditapes philippinarum), most exhibiting mortality prior to collection. All samples were shown to be infected by OsHV1. Viral genomes in three samples of C. gigas and three of R. philippinarum that originated from the same hatchery were unusual in bearing a deletion of at least 2.8 kbp in an inverted repeat... |
