Previous studies have demonstrated that <i>B. coli</i> 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 <i>B. coli</i>. In order to investigate the differences in gut microbiota and metabolites between healthy rhesus monkeys and those infected with <i>B. coli</i>, 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 <i>B. coli</i>. The results revealed significant differences in the composition of gut microbiota between rhesus monkeys infected with <i>B. coli</i> and healthy ones (<i>p</i> &lt; 0.01). The abundance of <i>Campylobacterota</i> was significantly increased (<i>p</i> &lt; 0.01), while the abundance of <i>Bacteroidota</i> was significantly decreased (<i>p</i> &lt; 0.05). <i>Prevotella</i> 9 was the dominant genus in both groups, showing a significant increase in the infected group (<i>p</i> &lt; 0.05). At the species level, <i>Brachyspira hampsonii</i> was significantly increased in the infected group (<i>p</i> &lt; 0.01), whereas <i>Prevotella copri</i>, which was the dominant species in both groups, showed a significant decrease in the infected group (<i>p</i> &lt; 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 <i>B. coli</i> (<i>p</i> &lt; 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 <i>B. coli</i> 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.</p>\u0000 </div>","PeriodicalId":16439,"journal":{"name":"Journal of Medical Primatology","volume":"54 2","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
