| Progeny of Crassostrea virginica oysters, introduced into France in 1992, were reared at 3 different locations. A survey was taken of these young C. virginica oysters during 1993. Histological and electron microscopical examination revealed a parasite interpreted as a Martelia-like protozoan in 1 oyster. The structure and the initial stages of the developmental cycle of this parasite are described for the first time in American oysters. However, no mature spores were detected. Thus, exact identification of the protozoan is difficult. This study indicates that American oysters could be infected with Marteilia spp. during cohabitation with Marteilia-infected native bivalves in France. |

| Of the 75 laboratories contacted through the survey, 54 answered, 14 of which are partially or totally devoted to mollusc diseases. In fact, only 4 laboratories are devoted full-time to this work. Of the 14 laboratories that declared to work on the diagnosis of mollusc diseases, 12 stated that they worked with mussels, 12 with oysters, 9 with clams and 8 with other mollusc species. This is coherent with available production information. According to production data in 2001 (FAO source), the main mollusc species in the region are the blue mussel, Mytilus edulis (297,485 tonnes), the Mediterranean mussel, Mytilus galloprovincialis (131,014 tonnes), the Pacific cupped oyster, Crassostrea gigas (127,323 tonnes, an important part of which is produced on the... |
