Overview

Comparative study reveals distinct gut microbiome structures and metabolic pathways between wild and captive black capuchin monkeys, indicating strong environmental influences on host microbiota.

Key Points

To compare the gut microbial diversity, taxonomic composition, and predicted functional potential between wild and captive populations of black capuchin monkeys (Sapajus nigritus).
Profiled the gut microbiomes of wild and captive black capuchin monkeys from southern Brazil using 16S rRNA gene sequencing.
Evaluated microbial diversity, community structure, differential taxonomic abundance, and predicted functional pathways using PERMANOVA, DESeq2, Random Forest classifiers, and PICRUSt2.
Host environment was significantly associated with gut bacterial community composition (PERMANOVA, p = 0.004), with captive individuals exhibiting greater overall microbial richness.
Wild monkeys were enriched in Pseudomonadota (notably Enterobacteriaceae and Morganellaceae), while captive monkeys displayed higher abundances of Bacteroidota (notably Bacteroidaceae and Dysgonomonadaceae), achieving a Random Forest classification AUC of 0.934.
Predicted functional profiling showed enrichment of amino acid biosynthesis, fatty acid β-oxidation, and mucin degradation in wild monkeys, whereas captive monkeys were enriched in pathways for aromatic and xenobiotic compound degradation.
