Plasmodium Circumflexum
''Plasmodium circumflexum'' is a parasite of the genus ''Plasmodium'' subgenus '' Giovannolaia''. Like all ''Plasmodium'' species ''P. circumflexum'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are birds. Taxonomy The parasite was first described by Kikuth in 1931 in a juniper thrush. It may have been the same species previous described by Labbe in 1894 who thought it was a species of ''Haemoproteus''. Description Schizonts: these are large and when mature may entirely encircle the erythrocyte nucleus. Merozoites: each schizont gives rise to 13-30 merozoites (mean 19.8: standard deviation 5). Gametocytes: these are large and when mature may entirely encircle the erythrocyte nucleus. Distribution This parasite is found in Argentina, Brazil, Canada, Germany, Italy, Malaysia, Morocco, South Africa, Sri Lanka and the United States.

Plasmodium
''Plasmodium'' is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects. The life cycles of ''Plasmodium'' species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. Parasites grow within a vertebrate body tissue (often the liver) before entering the bloodstream to infect red blood cells. The ensuing destruction of host red blood cells can result in malaria. During this infection, some parasites are picked up by a blood-feeding insect (mosquitoes in majority cases), continuing the life cycle. ''Plasmodium'' is a member of the phylum Apicomplexa, a large group of parasitic eukaryotes. Within Apicomplexa, ''Plasmodium'' is in the order Haemosporida and family Plasmodiidae. Over 200 species of ''Plasmodium'' have been described, many of which have been subdivided into 14 subgenera based on parasite morphology and host range.
