Here, we sequenced the transcriptomes and apicoplast genomes of three deep-branching apicomplexans, Margolisiella islandica, Aggregata octopiana, and Merocystis kathae. Phylogenomic analyses show that these taxa, together with Rhytidocystis, form a new lineage of apicomplexans that is sister to the Coccidia and Hematozoa (the lineages including ...

Aggregata octopiana was isolated from a pool of five infected octopuses (O. vulgaris) collected using traps by local fishermen in Ria de Vigo, Spain (24°14.09′N, 8°47.18′W). Aggregata oocysts were observed as white spots on the digestive tract with light microscopy. The oocysts were extracted from the caecum and intestine, and light ...
