To study the characteristics of development and morphology of E. granulosus of camel origin in north Xinjiang.
Six dogs were infected with protoscolices and then purged with arecoline at days 35 and 45 p.i.
Six dogs were heavily infected, the worm burden were 14,780 to 135,900 at days 35 and 45 p.i. At day 35 p.i. 77% of the had developed three segments, 10% contained mature eggs with fully developed "thickshelled" embryophores. Morphological studies revealed the following characteristics for 35-day-old worms; the mean length of the terminal segment accounted for 56% of the total worm length; the position of the sexually mature segment was always terminal (77%); the female reproductive system possessed an enlongated ovary with compact lobules; the Mehlis gland was covered by the vitelline gland and the testes were distributed throughout the segment arranging in a row posterior to the vitelline gland.
The E. granulosus of camel isolate in north Xinjiang can readily be distinguished from the horse, sheep, cattle and pig strains, but is similar to the camel (Camelus dromedarius) strain distributed in North Africa.
研究新疆北部骆驼源细粒棘球绦虫的发育和形态特征。
6只犬感染原头蚴,感染后第35天和第45天用槟榔碱驱虫。
6只犬感染严重,感染后第35天和第45天虫体负荷为14,780至135,900条。感染后第35天,77%的虫体已发育出3节,10%含有成熟卵及发育完全的“厚壳”胚膜。形态学研究显示35日龄虫体具有以下特征:末节平均长度占虫体总长度的56%;性成熟节片位置总是在末端(77%);雌性生殖系统有一个细长的卵巢,小叶紧密;梅氏腺被卵黄腺覆盖,睾丸分布于整个节片,在卵黄腺后方排成一排。
新疆北部骆驼分离株细粒棘球绦虫可轻易与马、羊、牛和猪株区分,但与分布于北非的骆驼(单峰驼)株相似。
