| Marteilia spp. are paramyxean parasites that affect several bivalve species of economic interest, such as Ostrea edulis and Mytilus galloprovincialis. Certain aspects of Marteilia spp., such as their life cycle and host affinity and infection dynamics, still remain unknown. The 'Delta de l'Ebre' constitutes a natural model for the study of the life cycle of the parasite Marteilia, since uninfected mussels and flat oysters immersed in the bays can become infected. This, along with the geographical and ecological characteristics of the bays, make it a very interesting location to study the Marteilia life cycle. Preliminary results concerning marteiliosis, mainly in mussels, such as prevalence dynamics, infectious periods, host affinity and host intermediate... |

| The life cycle of the species forming the genus Marteilia (Phylum Paramyxea), which are marine protozoan parasites of molluscs, is still poorly known, although there is evidence of the need for intermediate hosts. To date, only the calanoid copepod Acartia (Paracartia) grani has been demonstrated to be involved in the life cycle of the parasite infecting flat oysters growing in ponds with a low biodiversity. However, no complex natural environments, such as bays or estuaries, have been studied for a similar purpose. Therefore, a survey for the presence of the protozoan Marteilia was conducted by PCR on the zooplankton community of a natural ecosystem, the Alfacs and Fangar bays in the Delta de l'Ebre (NW Mediterranean). Identification of zooplankton... |

| Les parasites du genre Marteilia sont responsables de graves épizooties et sont retrouvés dans une communauté très variable de mollusques bivalves marins. Toutefois ces protistes restent difficiles à classer à l'intérieur du genre du fait que les données morphologiques sont insuffisantes pour distinguer avec précision deux espèces données. Ceci est le cas pour Martilia refringens, affectant l'huître plate Ostrea edulis ou la moule (Mytilus edulis et Mytilus galloprovincialis), Marteilia sp. et Marteilia maurini affectant les deux espèces de moules. C'est pourquoi, nous avons tenté d'isoler, par PCR, le gène codant pour l'ARN 18S, les ITS1 et ITS2 ainsi que le gène codant pour l'ARN 5,8S des parasites présents chez l'huître plate et la moule (M. edulis),... |
