Epigenetic phase variation in the gut microbiome enhances bacterial adaptation.
Article in Cell host & microbe, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The human microbiome continuously adapts to variations in diet and host physiology. Epigenetic phase variation (ePV) mediated by bacterial DNA methylation can generate phenotypic heterogeneity within clonal populations. ePVs have been characterized in human pathogens, but their roles in commensals remain unclear. Here, we cataloged ePVs in infant and adult gut microbiomes, revealing genome-wide and site-specific ePV in response to antibiotics and fecal microbiota transplantation. Long-read metagenomics revealed genome-wide ePV mediated by structural variations of DNA methyltransferases. Analysis of public short-read metagenomic datasets further revealed a high prevalence of genome-wide ePVs in the human microbiome. Site-specific ePVs were identified and associated with antibiotics or probiotic engraftment. Focusing on an Akkermansia muciniphila isolate, we find a specific ePV regulating mucC, a gene of unknown function but whose heterologous expression enhances bacterial tolerance to antibiotics via a bet-hedging strategy. Thus, epigenetic modifications are used by gut bacteria to adapt to fluctuating environments.
