| Marteilia refringens is a major pathogen of the European flat oyster, Ostrea edulis Linnaeus. Since its description, the lifecycle of this protozoan parasite has eluded discovery. Attempts to infect oysters experimentally have been unsuccessful and led to the hypothesis of a complex life-cycle involving several hosts. Knowledge of this life-cycle is of central importance in order to manage oyster disease. However, the exploration of M. refringens life-cycle has been previously limited by the detection tools available and the tremendous number of species to be screened in enzootic areas. In this study, these two restrictions were circumvented by the use of both molecular detection tools and a mesocosm with low biodiversity. Screening of the entire fauna of... |

| Paracartia grani originates from high latitudes and has progressively been recorded in the Mediterranean Sea since the 1980s. In Thau lagoon, while Acartia clausi and Acartia discaudata present maximum peaks of abundance from January to April and in November and December, both species being perennial over the year, P. grani and Paracartia latisetosa appear in May, develop during summer, in July and August, and slowly decrease in autumn before disappearing from the water column in December. The Acartiidae populations have changed over the years at our monitoring station. Indeed, P. latisetosa was last recorded in August 1983 while P. grani appeared in the lagoon in 1998. |
