''Plasmodium carmelinoi'' is a parasite of the genus ''Plasmodium''. Like all ''Plasmodium'' species ''P. carmelinoi'' has both vertebrate and insect hosts. The vertebrate hosts for this parasite are reptiles. ==Description== The parasite was first described by Lainson ''et al'' in 2010. 〔 〕 Prevalence of infection is low (5%). Trophozoites The trophozoites are initially tear-shaped and possess a large vacuole. As they mature they may assume an irregular shape but ultimately becoming spherical or broadly ovoid. The vacuole reduces the cytoplasm of the parasite to a narrow peripheral band. At first the dark, brownish-black pigment granules are restricted to this rim of cytoplasm but latterly become are concentrated within the vacuole. Schizonts These possess 8-12 nuclei and when mature are spherical to ovoid and predominantly polar in their position in the erythrocyte. Mature schizonts average 5.4 (4.4 - 6.6) x 4.9 (4.4 - 5.9) micrometres in size. Merozoites The merozoites measure approximately 2.0 x 1.0 micrometres. Gametocytes Mature gametocytes are polar in position and spherical to subspherical. Vacuoles of the gametocytes are smaller than those of the schizonts, are of ovoid or spindle shape and contain most of the pigment granules. Microgametocytes measure 6.0 (5.2 - 6.2) x 5.0 (4.4 - 5.2) micrometres and stain an over-all pink colour due to the dispersed nuclear chromatin. Macrogametocytes measure 5.7 (4.4 - 5.9) x 4.2 (4.0 - 5.1) micrometres and possess a compact, pink-staining nucleus and a clear blue, faintly staining cytoplasm. The sex ratio was 1 male to 2.2 females. 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 carmelinoi」の詳細全文を読む スポンサード リンク
