Verrucomicrobia

Significance#

Verrucomicrobia abundance (effectively Akkermansia abundance) is a reliable marker of gut health. Depleted by metal exposure: Toxic metals reduce Verrucomicrobia abundance, likely through disruption of mucin turnover and oxidative damage to the mucus layer.^{[1]Exposure to toxic metals triggers unique responses from the rat gut microbiotaRichardson JB, Dancy BCR, Horton CL et al. · 2018Open reference 1 ↓[2]Toxic and Essential Metals: Metabolic Interactions with the Gut Microbiota and Health ImplicationsQinheng Zhu, Boyan Chen, Fu Zhang et al. · 2024Open reference 2 ↓}

Depleted in disease: Consistently reduced in obesity, T2D, IBD, MS, and Parkinson's disease—mirroring Faecalibacterium depletion patterns.

Diet-responsive: Mediterranean diet and fiber-rich diets increase Verrucomicrobia abundance.^{[3]The interplay between diet and the gut microbiome: implications for health and diseaseFiona C.
