sp. is a common intestinal anaerobic parasite infecting non-human primates and many other animals. This taxon threatens the health of NHPs due to its high genetic diversity, impeding efforts to improve confined management and subsequent conservation practices. This study collected 100 and 154 fecal samples from captive macaques, gibbons, and slow lorises in the summer and winter, respectively. The infection, its gene subtypes, and its zoonotic potential based on small subunit ribosomal RNA (SSU rRNA) were analyzed. The prevalence of in the three primate genera was 57.79% (89/154) in the summer (2021) and 29.00% (29/100) in the winter (2020). Four zoonotic subtypes-ST1, ST2, ST3, and ST4-were identified. ST2 was the most prevalent subtype, suggesting that these animals may serve as reservoirs for pathogens of human infections. The macaques showed a more significant variation in infection between seasons than gibbons and slow lorises. The slow lorises in small cages and enclosure areas were potentially more infected by in the summer, indicating that inappropriate captive management may have detrimental effects on their health.
某物种是一种常见的肠道厌氧寄生虫，可感染非人类灵长类动物和许多其他动物。由于其高度的遗传多样性，这个分类群威胁着非人类灵长类动物的健康，阻碍了改善圈养管理及后续保护措施的努力。本研究分别在夏季和冬季从圈养的猕猴、长臂猿和懒猴中收集了100份和154份粪便样本。基于小亚基核糖体RNA（SSU rRNA）分析了该寄生虫感染情况、其基因亚型及其人畜共患病潜力。该寄生虫在三个灵长类属中的感染率在夏季（2021年）为57.79%（89/154），在冬季（2020年）为29.00%（29/100）。鉴定出了四种人畜共患病亚型——ST1、ST2、ST3和ST4。ST2是最普遍的亚型，表明这些动物可能是人类该寄生虫感染病原体的储存宿主。猕猴在该寄生虫感染方面的季节间差异比长臂猿和懒猴更为显著。夏季时，小笼舍和围场区域的懒猴感染该寄生虫的可能性更大，这表明不适当的圈养管理可能对它们的健康产生不利影响。
