从感染墨西哥利什曼原虫的仓鼠的肿大趾跖部位,切取病变组织,电镜观察原虫形态。无鞭毛体平均长度3.64μm。表膜分内外两层。膜下微管中心间距55.2nm。膜下微管总数约100～110根。鞭毛袋内藏鞭毛。鞭毛从基体发出。基体后部鞭毛公式为“9×2+O”,前部为“9×2+2”。动基体腊肠状。内腔中有高度弯曲的DNA纤丝。动基体有时与线粒体相连,表明前者具线粒体功能。墨西哥利什曼原虫的超微结构,与其他利什曼原虫相似。但原虫长度、膜下微管中心间距及膜下微管数有一定区别,可能为利什曼原虫的虫种鉴定提供线索。
From the swollen toe and plantar sections of hamsters infected with Leishmania meleagrides, diseased tissues were harvested and parasite morphology was observed by electron microscopy. The average length of amastigotes was 3.64 μm. Table film points inside and outside the two layers. Membrane microtubule center distance 55.2nm. The total number of microtubules under the membrane is about 100 to 110. Flagella bag containing flagella. Flagella emanate from the substrate. The posterior flagellum formula is “9 × 2 + O” and the front is “9 × 2 + 2”. Moving body sausage shape. There are highly curved DNA filaments in the lumen. The moving matrix is sometimes linked to the mitochondria, indicating that the former has mitochondrial function. The ultrastructure of Leishmania mexicana, similar to other Leishmania. However, the length of protozoa, the distance between the centers of microtubules and the number of microtubules under the membrane are different, which may provide clues for the identification of Leishmania species.
