杜氏利什曼原虫可简称为利杜体,它进入人体以后所引起的主要病理变化,就是网状内皮细胞的大量增加。网状内皮细胞又名巨噬细胞,系由网状纤维组织的微血管内皮所产生,具有吞噬异物的功用,故利杜体进入人体以后,即被网状内皮细胞所吞噬。网状内皮细胞虽有吞噬利杜体的能力,但不能把利杜体杀灭,反任其在细胞内增裂繁殖,最后 Leishmania donovani can be referred to as the lepidopteran, its main pathological changes caused after entering the human body, that is, a substantial increase in reticuloendothelial cells. Reticuloendothelial cells, also known as macrophages, are produced by the endothelium of reticular fibrous tissue and have the function of phagocytizing foreign bodies. Therefore, after reed enters the body, the reticulocytes are swallowed by reticuloendothelial cells. Although the reticuloendotheliosis relies on the capacity of phagocytosis, but can not kill the leudu body, the counterattack of its proliferation in the cell proliferation, and finally
