Abstract

Balantidium coli (B. coli) is a prevalent intestinal parasite in monkeys, significantly impacting their health. Previous studies have demonstrated that B. coli infection in pigs leads to severe dysregulation of the gut microbiota. However, there has been no report on the alterations in fecal microbiota and metabolites in rhesus monkeys infected with B. coli. In order to investigate the differences in gut microbiota and metabolites between healthy rhesus monkeys and those infected with B. coli, we conducted gene sequencing and gas chromatography–mass spectrometry (GC–MS) analysis of fecal samples from 6 healthy rhesus monkeys and 5 rhesus monkeys infected with B. coli. The results revealed significant differences in the composition of gut microbiota between rhesus monkeys infected with B. coli and healthy ones (p < 0.01). The abundance of Campylobacterota was significantly increased (p < 0.01), while the abundance of Bacteroidota was significantly decreased (p < 0.05). Prevotella 9 was the dominant genus in both groups, showing a significant increase in the infected group (p < 0.05). At the species level, Brachyspira hampsonii was significantly increased in the infected group (p < 0.01), whereas Prevotella copri, which was the dominant species in both groups, showed a significant decrease in the infected group (p < 0.05). Metabolomics studies indicated a significant decrease in levels of metabolites such as dihydrolipoamide, 9(Z),11(E)-Conjugated Linoleic Acid, and 8,9-DiHETrE within fecal samples from rhesus monkeys infected with B. coli (p < 0.05). Correlation analysis of the microbiome and metabolome suggested a close relationship between differential microbiota and metabolites. In conclusion, this study suggests that the colonization of B. coli is associated with dysbiosis of the monkey gut microbiota. This study provides a new insight that using intestinal microbes instead of antibiotics to treat balantidiosis can also serve as a reference for further research on the relationship between gut microbiota and metabolomics in host infections by other protozoa.

恒河猴感染大肠杆菌影响的微生物组代谢组学分析
大肠杆菌(Balantidium coli, B. coli)是猴子体内普遍存在的肠道寄生虫,严重影响它们的健康。先前的研究表明,猪的大肠杆菌感染会导致肠道微生物群的严重失调。然而,目前还没有关于恒河猴感染大肠杆菌后粪便微生物群和代谢物变化的报道。为了研究健康恒河猴和感染大肠杆菌恒河猴肠道菌群和代谢物的差异,我们对6只健康恒河猴和5只感染大肠杆菌恒河猴的粪便样本进行了基因测序和气相色谱-质谱(GC-MS)分析。结果显示,感染大肠杆菌的恒河猴与健康恒河猴肠道菌群组成存在显著差异(p < 0.01)。弯曲菌群丰度显著升高(p < 0.01),拟杆菌群丰度显著降低(p < 0.05)。普雷沃氏菌9为两组的优势菌属,感染组的普雷沃氏菌数量显著增加(p < 0.05)。在种水平上,感染组汉氏短螺旋体(Brachyspira hampsonii)的数量显著增加(p < 0.01),而作为两组优势种的copri普雷沃氏菌(Prevotella copri)在感染组的数量显著减少(p < 0.05)。代谢组学研究表明,在感染大肠杆菌的恒河猴粪便样本中,代谢物如二氢脂酰胺、9(Z)、11(E)-共轭亚油酸和8,9-二苯醚的水平显著降低(p < 0.05)。微生物组与代谢组的相关性分析表明,不同微生物群与代谢物之间存在密切关系。总之,本研究表明,大肠杆菌的定植与猴子肠道菌群的生态失调有关。本研究为利用肠道微生物代替抗生素治疗平衡体病提供了新的见解,也可为进一步研究其他原生动物感染宿主时肠道微生物群与代谢组学之间的关系提供参考。
