![]() pararefringens, they described a means of discriminating these taxa based upon a specific molecular diagnostic assay (Kerr et al. ![]() Although no morphological differences were reported between M. edulis from northern Europe, Marteilia parafringens. (2018) provided a basis for reinstating two separate species and named the species, that they detected mainly in M. However, based on molecular analysis, Kerr et al. refringens, for most effective health management. (2017) argued that they should conservatively be regarded as a single species, M. The World Organisation for Animal Health (Office international des épizooties, OIE) Reference Laboratory for Infection with Marteilia refringens recognises two types of Marteilia refringens, types O and M as defined by Le Roux et al. Others have supported this hypothesis that types M and O (for oysters and mussels, respectively) represent the same unique species, M. (2004) suggested that the form most commonly found in oysters and the other most commonly found in mussels to be separate strains of one species M. However, the molecular signatures of each was detected in both oysters and mussels (Le Roux et al.2001). Following the application of molecular tools, genetic differences were reported between the Marteilia isolates from oysters and mussels. galloprovincialis and Mytilus edulis as well as oysters ( Ostrea edulis) from other locations in the Mediterranean basin and on the Atlantic coasts of Europe (for details see the webpage on Marteilia spp. refringens has been clearly established, a morphologically similar parasite in mussels ( Mytilus galloprovincialis) from the Adriatic coast of Italy was named Marteilia maurini, (Comps et al. However, these parasites have been assigned to various higher taxa in the past (Perkins 1976, Ormières and Grizel 1979, Lauckner 1983, Berth et al. (1974a) described from Ostrea edulis and Marteilia-like parasites, are in the phylum Cercozoa and order Paramyxida (Cavalier-Smith and Chao 2003, Feist et al.
