Aggregata
''Aggregata'' is a genus of parasitic alveolates belonging to the phylum Apicomplexa. Taxonomy The organism found in the octopus was first named as ''Benedenia octopiana'' by Schneider in 1875. Since ''Benedenia'' was preoccupied, ''Eucoccidium'' was proposed as a replacement name by Lühe in 1903. The genus ''Aggregata'' was named by Frenzel in 1885 for parasites in a crustacean. These were later shown as two stages in the lifecycle of an identical organism by Léger and Duboscq. This genus appears to be related to the adelinids and ''Hepatozoon'' but this needs confirmation.Kopecná J, Jirků M, Oborník M, Tokarev YS, Lukes J, Modrý D (2006) Phylogenetic analysis of coccidian parasites from invertebrates: search for missing links. Protist 157(2):173-183 Life cycle The life cycle was determined in 1914. These parasites are heteroxenous, with two hosts in their life cycle. Sexual stages are found in the digestive tract of cephalopods and asexual stages infect the digestive tr ...
