''Novyella'' is a subgenus of the genus ''Plasmodium'' - all of which are parasitic protozoa. The subgenus was created in 1963 by Corradetti ''et al.''. Species in this subgenus infect birds. It unites the avian malaria parasites with small erythrocytic meronts and elongated gametocytes. The type species is ''Plasmodium vaughani''. This subgenus was created on the basis of morphology. Subsequent DNA studies showed it to be polyphetic. It has been revised by Landau ''et al'' and currently contains only those species with a white/blue globule in the cytoplasm. Several of the species that were included in this subgenus have now been moved to a new subgenus ''Papernaia''. == Diagnostic features == Species in the subgenus ''Novyella'' have the following characteristics: * Mature schizonts are either smaller than or only slightly larger than the host nucleus. They contain scanty cytoplasm. * Gametocytes are elongated. Sexual stages in this subgenus resemble those of ''Haemoproteus''. * Exoerythrocytic schizogony occurs in the mononuclear phagocyte system * A blue, pale blue or white globule, frequently refractory, can be found in the cytoplasm. 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「Novyella」の詳細全文を読む スポンサード リンク
