Summary Mikrocytos mackini is an intracellular protistan parasite of oysters whose position in the phylogenetic tree of eukaryotes has been a mystery for many years Results and Discussion Mikrocytos mackini Is a Derived Rhizarian Few eukaryotes are of a completely unknown evolutionary origin. Despite ultrastructural and molecular studies, the enigmatic microcell parasite Mikrocytos mackini, which is the causative agent of the Denman Island disease in oysters, is one such orphan lineage M. mackini cells are not easily separated from its Pacific oyster host, Crassostrea gigas To determine the relationship of M. mackini to other eukaryotes, we first analyzed a broad taxon sampling of 101 operational taxonomic units (OTUs), including representatives of all supergroups and lineages with no strong affiliation, such as Collodictyon, Thecamonas, or Picobiliphytes
