''Plasmodium juxtanucleare'' is a parasite of the genus ''Plasmodium'' subgenus ''Bennettinia''. Like all ''Plasmodium'' species ''P. juxtanucleare'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are birds. ==Description== This species was first described in 1941 by Versiani and Gomes.〔Versiani, V. & Gomes, B. F. 1941 Sobre um novo hematozoario da galinha: ''Plasmodium juxtanucleare'' n.sp. (Nota previa). Revista Brasileira de Biologia 1, 231–233.〕 The subgenus is named after Professor Gordon F. Bennett. Parasite densities tend to be low (0.1–1% infected erythrocytes). Multiple infections of the same erythrocyte may occur. The trophozoites have scanty cytoplasm and are irregular in shape. When fully grown they may be round,oval or irregular. They adhere closely to the nucleus and have 1-2 pigment granules. While a vacuole may be present there is no ring form unlike that of other species. The trophozoites produce two to six merozoites per erythrocyte. The merozoites have scanty cytoplasm and do not exceed the size of the nucleus when fully developed. The schizonts are small and always found juxtaposed to the erythrocyte nucleus. The gametocytes resemble those of ''Plasmodium relictum'' and may displace the nucleus. They are of variable shape:oval, round, elongated or even irregular. They do not exceed the size of the nucleus. Perhaps the most characteristic feature of this genus is the formation of pedunculated oocyts in the mosquito midgut. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plasmodium juxtanucleare」の詳細全文を読む スポンサード リンク
