An ultrastructural study on the amastigote stage of Leishmania donovani, in a rare case of laringeal involvement, was carried out. Many details of the fine morphology of this protozoon were observed under the electron microscope, i.e.: the outer membrane of host origin, periplast, subpellicular microtubules, kinetoplast, flagellum, flagellar pocket, multivesicular bodies. A presence of a new organelle (4 microtubules structure close to and running parallel to the flagellar pocket), previously not described in Leishmania donovani's species, was demonstrated in this indigenous strain (from Central Italy). The Authors found a limited number of subpellicular microtubules in this strain, i.e.: 72 microtubules. Differences in size and number of microtubules between strains must be investigated in more rigorous morphometric studies. It's possible that the number of the subpellicular microtubules represents a new taxonomic character.
对罕见的喉部受累的杜氏利什曼原虫无鞭毛体阶段进行了超微结构研究。在电子显微镜下观察到了该原生动物精细形态的许多细节，即：宿主来源的外膜、表膜、表膜下微管、动质体、鞭毛、鞭毛袋、多囊泡体。在该本土菌株（来自意大利中部）中发现了一种新的细胞器（靠近鞭毛袋并与之平行排列的4微管结构），此前在杜氏利什曼原虫物种中未被描述过。作者发现该菌株中的表膜下微管数量有限，即72根微管。菌株之间微管大小和数量的差异必须在更严格的形态计量学研究中进行调查。表膜下微管的数量有可能代表一个新的分类学特征。
