Abstract: 【Objective】 This experiment was aimed to study the changes and diversity of gut microbiota in rhesus monkeys(Macaca mulatta) infected with Trichomonas using 16S rDNA sequencing technology,provide a reference for clinical research on using microbiota as an alternative antibiotics for treating trichomoniasis. 【Method】 Six samples of rhesus monkeys infected with Trichomonas and six samples of Trichomonas-negative fresh feces from rhesus monkeys were collected for predictive analysis of gut microbiota and functional genes through metagenomic sequencing. 【Result】 The diversity of gut microbiota in Trichomonas-infected rhesus monkeys decreased significantly compared to healthy rhesus monkeys,leading to significant changes in microbial community composition.Specifically,there was a significant decrease in Bacteroidota and Fibrobacterota (P<0.05),while Campylobacta and Desulfobacterota showed a significant increase (P<0.05).Additionally,Lactobacillales,Campylobacter and Campylobacteraceae were significantly enriched in the intestinal microbes of Trichomonas-infected rhesus monkeys,whereas Prevotella_9,Bacteroidales and Bacteroidota were significantly enriched in the intestinal microbes of Trichomonas-negative rhesus monkeys.Furthermore,Brachyspira_hampsonii and Prevotellaceae_bacterium_Marseille_P2831 were identified as biomarkers of Trichomonas-infected rhesus monkeys.The functional gene prediction of gut microbiota also revealed a significant decrease in the biosynthesis function of amino acids and antibiotics in the Trichomonas-infected rhesus monkeys (P<0.05). 【Conclusion】 Infection with Trichomonas could lead to a reduction in the diversity of gut microbiota and an alteration in the composition of the microbial community in rhesus monkeys.Additionally,it could also decrease the biosynthetic function of gut microbiota.
