We examined stool samples for trophozoites of the entodiniomorphid ciliate Troglodytella abrassarti Brumpt and Joyeux, 1912, from a habituated group of chimpanzees (Pan troglodytes schweinfurthii) at Mahale Mountains National Park in western Tanzania. In our study, fresh fecal samples from identified individuals were collected immediately after defecation and fixed in 10% formalin. In total, 52 samples from 38 chimpanzees (61% of 62 chimpanzees in the group) were examined using a direct smear method. A stool sample from an individual collection date from an individual chimpanzee was examined up to 3 separate times before it was called negative. Forty-eight (92%) of the 52 samples were positive, and stools from 37 (97%) of the 38 chimpanzees were positive for trophozoites of T. abrassarti. The high prevalence of T. abrassarti in these chimpanzees is consistent with previous reports of this organism in chimpanzees.
我们对来自坦桑尼亚西部马哈勒山脉国家公园一群习惯化黑猩猩（Pan troglodytes schweinfurthii）的粪便样本进行了检查，以寻找1912年Brumpt和Joyeux所描述的内毛目纤毛虫——阿氏穴居纤毛虫（Troglodytella abrassarti）的滋养体。在我们的研究中，已识别个体排便后立即采集新鲜粪便样本，并固定于10%福尔马林中。总共对38只黑猩猩（该群体62只黑猩猩中的61%）的52份样本采用直接涂片法进行了检查。来自一只黑猩猩的单个采集日期的粪便样本，在判定为阴性之前最多检查3次。52份样本中有48份（92%）呈阳性，38只黑猩猩中有37只（97%）的粪便中阿氏穴居纤毛虫滋养体呈阳性。这些黑猩猩中阿氏穴居纤毛虫的高感染率与之前关于该生物体在黑猩猩中的报道一致。
