“…This parasite is morphologically different from M. islandica and apparently all other apicomplexan species previously described from bivalves. In addition, it seems to be the only one infecting muscle cells (Kristmundsson et al, 2011). Apart from the present paper and the one of Kristmundsson et al, 2011, the only paper published on parasites of Iceland scallop is that of Giguere et al (1995), who studied the cause of mass mortalities of sea scallops Plagopecten magellanicus and Iceland scallops occurring in Canadian waters.…”
