目的：研究新疆北部双峰驼细粒棘球绦虫的发育与形态特征。方法：用棘球蚴原头节感染家犬，观察成虫在犬体内的发育。对３５ｄ成虫进行形态学的观察和描述。结果：用原头节感染的６只家犬，在感染后３５ｄ和４５ｄ用槟榔碱驱虫，每只犬驱出成虫１４７８０至１３５９００条。３５ｄ的成虫中有１０％虫体已含有厚壳虫卵，表明有感染性。７７％的成熟体节位于虫体末端，最多体节数为３。虫体总长２．５±０．７ｍｍ，成虫平均顶突钩数３２．７±１．２，外形光滑。平均睾丸数３２．４±３．９，分布于整个成熟体节，在卵黄腺后排成一排。卵巢明显较长，有不明显的分叶，卵黄腺长形并掩盖梅氏腺。结论：新疆北部双峰驼细粒棘球绦虫在形态学上与北非骆驼株细粒棘球绦虫相似，可能是分布在我国的细粒棘球绦虫骆驼株。但与骆驼株亦有不同之处，应进一步鉴定。
Objective: To study the development and morphological characteristics of Bacillus cereus in Bactrian camel in northern Xinjiang. Methods: Infected dogs were infected with Echinococcus multilocularis to observe the development of adults in dogs. Morphological observation and description of 35d adults. Results: Six domestic dogs infected with primordial nostrils were repelled by arecoline at 35d and 45d after infection. Each dog was able to drive out 14,780-153,900 adult worms. 10% of 35d adult worms already contain thick-shell eggs, indicating infectivity. 77% of the mature body segments are located at the end of the parasites and the maximum number of segments is 3. The total length of worms is 2.5 ± 0.7mm, the average number of adult protoceptor hooks is 32.7 ± 1.2, and the shape is smooth. The average number of testis 32.4 ± 3.9, distributed throughout the mature body section, in the yolk glands arranged in a row. Obviously longer ovaries, with obscure lobulations, long yolk glands and cover the Meyer’s gland. CONCLUSION: The Bactrian hornworm of Bactrian camels in northern Xinjiang are similar in morphology to the camelid Echinococcus granulosus in North Africa and may be the camelid of Echinococcus granulosus distributed in China. However, there are also differences with the camel strains and should be further identified.
