| Summary: | The contributions and interactions of multi-kingdom microbiota (i.e. bacteriome, mycobiome, archaeome, and phageome) with serum metabolome and host phenome in healthy individuals under moderate altitude exposure remain unclear. We applied shotgun metagenomic sequencing in feces and targeted metabolomics technology in serum to explore how human gut multi-kingdom microorganisms influence the serum metabolome and phenome in healthy Chinese individuals following moderate altitude exposure. The results indicated that individuals with moderate altitude exposure exhibited more substantial alterations in gut bacteriome and phageome compared to those in mycobiome and archaeome. Both intra-kingdom and inter-kingdom correlations at baseline were denser than those following moderate altitude exposure. Bacteriophages-host interaction analysis revealed symbiosis between bacteriophages and Bacteroidetes, Proteobacteria, and short-chain fatty acids (SCFAs) producers. Furthermore, bacteriophage Shirahamavirus PTm1 (odds ratio (OR) = 3.82; 95% confidence interval (CI): 1.20–12.16), archaeon Crenarchaeota (OR = 3.70; 95% CI: 1.35–10.14) and bacterium Bacteroidetes (OR = 3.69; 95% CI: 1.34–10.15) showed a positive association with lowered fasting blood glucose (FBG) benefits, while bacteriophage Candidatus Nitrosopelagicus brevis (OR = 0.30; 95% CI: 0.10–0.89) and butyric acid (OR = 0.07; 95% CI: 0.01–0.37) exhibited a negative association with lowered FBG benefits. These findings suggest that targeting gut multi-kingdom microorganisms could serve as an alternative therapeutic approach to mitigate dysglycemia and its associated metabolic disorders. |
