| Plasmodium durae | A species that is the cause of an acute and often fatal malaria of young turkeys in Africa. (05 Mar 2000) |
|---|---|
| plasmodium falciparum | A species of protozoa that is the causal agent of falciparum malaria (malaria, falciparum). It is most prevalent in the tropics and subtropics. (12 Dec 1998) |
| plasmodium gallinaceum | A protozoan parasite that causes avian malaria (malaria, avian), primarily in chickens, and is transmitted by the aedes mosquito. (12 Dec 1998) |
| Plasmodium juxtanucleare | A species that is a cause of chicken malaria in Mexico and South America, and in Sri Lanka and Malaysia. (05 Mar 2000) |
| plasmodium knowlesi | A protozoan parasite from southeast asia that causes monkey malaria. It is naturally acquired by man in malaysia and can also be transmitted experimentally to humans. (12 Dec 1998) |
| Plasmodium kochi | A Plasmodium species now recognised as Hepatocystis kochi. (05 Mar 2000) |
| plasmodium malariae | A protozoan parasite that occurs primarily in subtropical and temperate areas. It is the causal agent of quartan malaria. As the parasite grows it exhibits little ameboid activity. (12 Dec 1998) |
| Plasmodium ovale | A species that is the agent of the least common form of human malaria; resembles Plasmodium vivax in its earlier stages, but often modifies the cell membrane, causing it to form a fimbriated outline, and often assume an oval shape; Schuffner's dots are abundant and appear early, host cells are normal or only slightly enlarged, and only about 8 to 10 grapelike merozoites are produced; fever is tertian (every 48 hours), and relapses are infrequent. (05 Mar 2000) |
| Plasmodium relictum | A species of worldwide distribution found in pigeons, doves, ducks, swans, and a great variety of other birds; it is highly pathogenic in pigeons, game birds, and others to which this strain is poorly adapted, causing anaemia, weakness, and often death. (05 Mar 2000) |
| plasmodium vivax | A protozoan parasite that causes vivax malaria (malaria, vivax). This species is found almost everywhere malaria is endemic and is the only one that has a range extending into the temperate regions. (12 Dec 1998) |
| plasmodium yoelii | A species of plasmodium causing malaria in rodents. (12 Dec 1998) |
| Plasmodromata | A former taxonomic category that included ameboid and flagellate Protozoa in which the nucleus is not separated into reproductive (micro-) and vegetative (macro-) portions; equivalent to the present phylum Sarcomastigophora. Origin: plasmo-+ G. Dromos, a running, a course (05 Mar 2000) |
| plasmogamy | Union of two or more cells with preservation of the individual nuclei; formation of a plasmodium. Synonym: plasmatogamy, plastogamy. Origin: plasmo-+ G. Gamos, marriage (05 Mar 2000) |
| plasmogen | <biology> The important living portion of protoplasm, considered a chemical substance of the highest elaboration. Germ plasm and idioplasm are forms of plasmogen. Origin: Plasma + -gen. Source: Websters Dictionary (01 Mar 1998) |
| plasmoid | <physics> An isolated plasma which holds together for a duration much longer than the collision times for the constituent particles. (09 Oct 1997) |
