A retrospective study of cecal and colonic tissues from 28 squirrel monkeys (Saimiri sciureus and Saimiri boliviensis) demonstrated enteric trichomonads within luminal crypts. Twenty-one of 28 (75%) had trichomonads in the mucosal epithelium either in cup-like depressions or intraepithelial vacuoles. Organisms were also beneath the superficial luminal mucosal epithelium and between the basement membrane and crypt epithelial cells. Immunoperoxidase staining also identified organisms within the lamina propria and submucosa. Additional histologic changes included mucosal ulceration, multifocal cryptitis, and focal epithelial necrosis. Most areas containing trichomonads did not have an associated inflammatory response.
对28只松鼠猴（松鼠猴和玻利维亚松鼠猴）的盲肠和结肠组织进行的一项回顾性研究表明，在管腔隐窝内发现了肠道毛滴虫。28只中有21只（75%）在杯状凹陷或上皮内空泡的黏膜上皮中有毛滴虫。微生物也存在于浅表管腔黏膜上皮下方以及基底膜和隐窝上皮细胞之间。免疫过氧化物酶染色还在固有层和黏膜下层发现了微生物。其他组织学变化包括黏膜溃疡、多灶性隐窝炎和局灶性上皮坏死。大多数含有毛滴虫的区域没有相关的炎症反应。
