This study was undertaken to determine the prevalence of anoplocephalid cestodes in sheep and goats in Senegal. Intestines of 462 sheep and 48 goats were examined; 47.4% of sheep and 6.2% of goats were infected. The species identified and their prevalence were, among sheep, Avitellina centripunctata 38.7%, Moniezia expansa 15.4%, Stilesia globipunctata 16.7%, and Thysaniezia ovilla 0.4%. Among goats, they were M. expansa 6.2% and T. ovilla 2.1%. The prevalence of all species was not statistically different between dry and rainy seasons. The infections were single or multiple. Indeed, 56.2% of sheep were infected by a single species, 37.4% by two species, and 6.4% by three species. For goats, 66.7% were infected by M. expansa and 33.3% by both M. expansa and T. ovilla. Scanning electron microscopic (SEM) observations of tapeworms show the general diagnosis characters of these species.
本研究旨在确定塞内加尔绵羊和山羊中裸头绦虫的感染率。对462只绵羊和48只山羊的肠道进行了检查；47.4%的绵羊和6.2%的山羊受到感染。在绵羊中鉴定出的种类及其感染率分别为：中心无卵黄腺绦虫38.7%、扩展莫尼茨绦虫15.4%、球形无卵黄腺绦虫16.7%和卵形曲子宫绦虫0.4%。在山羊中，扩展莫尼茨绦虫为6.2%，卵形曲子宫绦虫为2.1%。所有种类的感染率在旱季和雨季之间无统计学差异。感染情况为单一感染或多重感染。实际上，56.2%的绵羊感染单一物种，37.4%感染两种物种，6.4%感染三种物种。对于山羊，66.7%感染扩展莫尼茨绦虫，33.3%同时感染扩展莫尼茨绦虫和卵形曲子宫绦虫。绦虫的扫描电子显微镜（SEM）观察显示了这些物种的一般诊断特征。
