从新疆北部地区感染囊型包虫病的骆驼肝、肺包囊中收取细粒棘球蚴原头节，实验感染家犬后，分别于第３５天和第４５天收集成虫进行扫描电镜观察。骆驼源细粒棘球绦虫成虫的外部形态特点：整个虫体表面被覆着微毛，与其他来源的成虫相比，其微毛相对浓密柔细，成熟体节的生殖孔有两种不同的形态：有雄茎伸出的生殖孔凹陷不明显，孔周区没有感觉乳头出现。在雄茎表面密布丝状微绒毛；没有雄茎伸出的生殖孔凹陷明显，孔周区有许多大小不等的感觉乳头，其形态特殊，可作为虫株鉴定的依据。成虫之间的异体交配可能是细粒棘球绦虫常见的生殖方式。讨论了感觉器官在异体交配时可能具有株内识别和株间排斥的功能 From the camel liver infected with cystic echinococcosis in northern part of Xinjiang, the protoscolei of Echinococcus granulosus was collected from the lung cysts. After infected with the experimental dogs, the adult worms were collected on the 35th and 45th day for scanning electron microscopy. The external morphology of the camelid Echinococcus granulosus: The entire surface of the worm is covered with the hairy micro-hair, which is relatively dense and soft compared with the adults of other origins. The reproductive pores of the mature body have two different morphologies: A male stem out of the reproductive hole depression is not obvious, there is no feeling around the nipple nipple appear. In the male stem surface dense filamentous microvilli; no male stems protruding genital hole depression obvious, peri-hole area has many sizes of nipples, its special shape, can be used as identification of the basis of the strain. Allogenic mating between adults may be common reproductive methods of Echinococcus granulosus. Discusses the function of sensory organs that may have intraspecific recognition and interspecies exclusion at mating
