Gastrointestinal microbiome plays an important role in animal metabolism, immune system and pathology associated with health and disease. Many wild slow lorises were confiscated from illegal trade into captivities and experienced a range of changes in living environment and diet. Microbiome analysis contributes to improving captive management by identifying the alteration in their gastrointestinal microbial communities and aiding in determining the factors affecting the health of captive slow lorises. The fecal samples of eighteen Bengal slow lorises (Nycticebus bengalensis) were used to compare gut microbiota from four rescue centers located in Dehong, Gejiu, Nanning and Puer cities of China. The results showed a significant site-dependent difference in microbial community diversity. Similar to other Lorisinae species, the Phyla including Bacteroidetes, Firmicutes and Proteobacteria dominated their gut microbiome composition. The Gejiu group exhibited a higher overall diversity and the unique OTUs, which is resulted from long-term isolated husbandry and heavy human disturbances. The scarcity of gums in the captive diet was likely to cause a lower abundance of Prevotella associated with soluble fiber degradation. The variation of intestinal microbiota in different environments highlights the necessity to improve feed preparation and husbandry management for the captive Bengal slow lorises.
胃肠道微生物群在动物新陈代谢、免疫系统以及与健康和疾病相关的病理学中发挥着重要作用。许多野生懒猴从非法贸易中被没收并圈养起来，其生活环境和饮食发生了一系列变化。微生物群分析有助于通过识别圈养懒猴胃肠道微生物群落的变化，并协助确定影响圈养懒猴健康的因素，从而改善圈养管理。本研究使用了来自中国德宏、个旧、南宁和普洱四个救助中心的18只孟加拉懒猴（Nycticebus bengalensis）的粪便样本，比较其肠道微生物群。结果显示，微生物群落多样性存在显著的地点依赖性差异。与其他懒猴科物种相似，包括拟杆菌门、厚壁菌门和变形菌门在内的菌门主导了它们的肠道微生物群组成。个旧组表现出更高的总体多样性和独特的操作分类单元，这是长期隔离饲养和严重人为干扰的结果。圈养饮食中树胶的稀缺可能导致与可溶性纤维降解相关的普雷沃氏菌丰度降低。不同环境中肠道微生物群的变化凸显了改善圈养孟加拉懒猴饲料制备和饲养管理的必要性。
