Contribution à l'étude du cycle de Marteilia refringens, parasite de l'huître plate, Ostrea edulis ArchiMer
Zerabib, Maamar.
Pour le premier point, l'étude des maladies chez les bivalves marins repose jusqu'à présent essentiellement sur l'histologie classique, parfois 'couplée ' à la inicroscopie électronique à transmission.  Toutefois, ces techniques, consommatrices de temps, présentent des limites notamment au niveau de la capacité de traitement de nombreux échantillons. Il semble alors, indispensable aujourd'hui de développer de nouveaux outils de diagnostic basés notamment sur l'immunologie et la biologie moléculaire. Pour le second point, le développement de population d'animaux "résistants" à certaines pathologies peut constituer une voie très prometteuse, dont l'exploration permettra d'obtenir un moyen de lutte contre les maladies des mollusques marins. La reproduction de...

Experimental transmission of Marteilia refringens with special consideration of its life cycle ArchiMer
Berthe, Franck; Pernas, Maria; Zerabib, Maamar; Haffner, Philippe; Thebault, Anne; Figueras, Antonio.
Ever since its first description the paramyxean parasite Marteilia refringens has been recognised as one of the most significant pathogens of bivalve molluscs. The existence of a complex life cycle has been postulated by many authors. However, the transmission route of M. refringens and its life cycle remain unresolved. Experimental observations are presented here that may help lead to a satisfactory hypothesis of the M. refringens life cycle. Trials were performed to test the infectivity of purified early and late stages of M. refringens by different routes of inoculation. Horizontal transmission was also tested by cohabitation with carriers in experimental tanks. Field cohabitation and exposure to natural sources of the parasite helped examine the role...

Que savons-nous des Marteillia? ArchiMer
Berthe, Franck; Haffner, Philippe; Zerabib, Maamar; Rodriguez, David.
Marteilia refringens, a parasitic protist, is partially responsible for the drastic reduction in French production of the European flat oyster (Ostrea edulis) in the 1970s and still constitutes a major obstacle for revitalizing coastal farming of this species.
