Abstract

The genus Entamoeba infects both humans and NHPs. In zoos, visitors feeding significantly increases the frequency of human-to-NHP contact, thereby raising the risk of zoonotic transmission. In this study, six Entamoeba species were investigated and analyzed in the fecal samples of 14 NHP species from zoos in Beijing, Guiyang, Shijiazhuang, Tangshan, and Xingtai in China. A total of 19 out of 84 primate fecal samples tested positive for Entamoeba spp. by polymerase chain reaction (PCR). Among these, 14 samples contained mono-detections of E. coli (7/84), E. dispar (4/84), and E. polecki (3/84). Five samples were found to have mixed detections with two or three species, suggesting the potential for zoonotic transmission; however, no pathogenic E. histolytica, E. moshkovskii, or E. nuttalli were detected. This study provides new insights into parasitic detections in NHPs in Chinese zoos and offers valuable background information for the prevention and control of zoonotic parasitic diseases.

中国动物园非人类灵长类动物内阿米巴流行病学及分子特征研究。

内阿米巴原虫属既感染人类也感染NHPs。在动物园，游客进食大大增加了人类与新冠病毒接触的频率，从而增加了人畜共患病传播的风险。本研究对北京、贵阳、石家庄、唐山和邢台4个动物园的14种NHP动物粪便样本中的6种内阿米巴进行了调查和分析。经聚合酶链反应（PCR）检测，84份灵长类动物粪便样本中有19份内阿米巴原虫呈阳性。其中，大肠杆菌（7/84）、迪帕埃希菌（4/84）和波列茨基埃希菌（3/84）单检出14份。发现5个样本中有两种或三种混合检测，表明可能存在人畜共患病传播；未检出致病性溶组织大肠杆菌、莫什科夫斯基大肠杆菌和努塔利大肠杆菌。本研究为我国动物园NHPs寄生虫检测提供了新的思路，为人畜共患寄生虫病的预防和控制提供了有价值的背景资料。
