在肯尼亚的不同地区从人和动物体内分离出5株利什曼原虫,但无法确定其在利什曼病流行病学上的意义。作者采用DNA浮力密度、酶电泳谱变异型和分泌因素血清型等生化技术进行了研究。结果发现,从内脏利什曼病患者分离出的虫株的生化指标是一致的,其中3株来自肯尼亚的西北部,2株来源于基图伊地区,两个疫区互不相连,说明两地的流行病学特征虽不相同,但原虫在生化方面的特性完全一样。在过去不少学者曾对噬齿动物能否作为人内脏利什曼病的保虫宿主进行了研究,并已证明非洲砂鼠体内分离出的原虫不是杜氏
Five Leishmania isolates were isolated from humans and animals in different parts of Kenya, but their epidemiological significance in leishmaniasis can not be determined. The authors used biochemical techniques such as DNA buoyant density, enzyme-linked immunosorbent variation, and sero-type serotypes. The results showed that biochemical markers of isolates from visceral leishmaniasis were consistent, of which 3 were from the northwestern part of Kenya, 2 from the Kitui area and the other 2 were not connected, indicating that two The epidemiological characteristics of the land are not the same, but the biochemical characteristics of protozoa are exactly the same. In the past, many scholars have conducted studies on whether or not biodsters can serve as a host for preservation of human visous leishmaniasis and have shown that protozoa isolated from African sand rats are not Duchenne
