The species composition, prevalence, and average relative abundance of rumen ciliates were analyzed in 16 Brazilian sheep. 28 species of ciliates were identified belonging to 3 families: Isotrichidae, Ophryoscolecidae, and Parentodiniidae. Among these ciliates, Entodinium alces, Metadinium esalqum, and M. rotundatum were found for the first time in sheep, and other 12 species for the first time in Brazilian sheep. Different morphotypes of parentodiniid ciliates were identified in 7 of the 16 sheep analyzed and this is the second report of this family in ruminants. The species Entodinium contractum was redescribed based on the new data on the general morphological features; for the first time, we described the oral infraciliature, which in this species is of the Entodinium-type. In this species, it is noteworthy that the prominent vestibular polybrachykinety can be used as an important identifying characteristic.
对16只巴西绵羊的瘤胃纤毛虫的物种组成、流行率和平均相对丰度进行了分析。鉴定出28种纤毛虫，分属于3个科：等毛科、奥氏科和原多甲科。在这些纤毛虫中，阿尔氏内毛虫、埃氏中肠甲纤毛虫和圆形中肠甲纤毛虫首次在绵羊中被发现，另有12种首次在巴西绵羊中被发现。在分析的16只绵羊中的7只中鉴定出了原多甲科纤毛虫的不同形态型，这是该科在反刍动物中的第二次报道。根据一般形态特征的新数据对收缩内毛虫进行了重新描述；我们首次描述了口下纤毛系，该物种的口下纤毛系属于内毛虫型。在该物种中，值得注意的是，突出的前庭多短动基列可作为一个重要的鉴别特征。
