| a vibrio splendidus strain is associated with summer mortality of juvenile oysters crassostrea gigas in the bay of morlaix (north brittany, france). | juvenile oysters crassostrea gigas cultured in the bay of morlaix (france) have suffered unexplained summer mortalities for over a decade. in the present study, we tested the hypothesis that a bacterial pathogen could be responsible for this phenomenon. a first attempt failed to isolate a bacterial pathogen from moribund or weak oysters. only non-pathogenic, probably opportunistic, bacteria were isolated. as an alternative approach, we focused on oysters presenting reduced stress-response capaci ... | 2001 | 11678229 |
| patterns of experimental contamination by protogonyaulax tamarensis in some french commercial shellfish. | as a result of the proliferation of toxic marine dinoflagellates along european coasts and the recent discovery of paralytic poisons in french shellfish, experimental studies were conducted on four species of shellfish from the brittany coasts. contamination rates of a culture of toxic protogonyaulax tamarensis, were determined for mytilus edulis, crassostrea gigas, pecten maximus and ruditapes philippinarum. mussels and scallops were very rapidly contaminated showing high toxin accumulation rat ... | 1989 | 2629173 |
