摘要: 青藏高原东部是细粒棘球绦虫和多房棘球绦虫的混合流行区,诸多的家畜和野生动物参与了棘球绦虫的传播。近年来,一种未知的棘球绦虫先后从高原鼠兔(Ochotona curzoniae)和藏狐(Vulpes ferrilata)中被分离出来。由于其特有的形态学、分子遗传学、寄生宿主和地理分布特征,而被作为新种 ——— 石渠棘球绦虫(Echinococcus shiquicus,Xiao et al,2005)进行了系统研究。本文对该虫种的生物遗传学和流行病学特征进行了讨论,并提出了理论上的假设来解释一些仍不十分清楚的现象。

Abstract: In the eastern Qinghai-Tibet Plateau region, a variety of domestic and wild mammals are involved in the transmission cycles of Echinococcus species. E. granulosus and E. multilocularis are known being sympatrically distributed in the plateau region. Recently, an unknown Echinococcus species was isolated from infected plateau pika (Ochotona curz-oniae) and Tibetan fox (Vulpes ferrilata). The species shows quite distinct characteristics on morphology,genetics, host specificity and geographical distribution from others. It was therefore identified as a new Echinococcus species, Echinococcus shiquicus. This paper discussed the biological genetics and epidemiological features of the species, and proposed hypotheses and considerations for further exploration.
