Marteilia refringens is a protozoan parasite recognized as a significant pathogen of the European flat oyster Ostrea edulis. The life cycle of this species is still poorly known, although there is evidence of the need for intermediate host(s). In the present study, we have used molecular approaches to identify this parasite in samples of the dwarf oyster Ostrea stentina after reports of massive mortality along the Tunisian coasts. In 2009 we evaluated the status of O. stentina from Monastir and checked if there was an infection with M. refringens, using polymerase chain reaction assays. Of the 103 tested O. stentina, 85 were PCRpositive using a Marteilia genus-specific assay. Additional assays were subsequently carried out on some samples collected in 2010...
