Bacteroides eggerthii ameliorates metabolic dysfunction-associated steatotic liver disease through host-microbe signaling and highlights 2-hydroxyisocaproate as a potential effector.
Article in Clinical and molecular hepatology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND/
aimsGut microbiome plays a pivotal role in metabolic dysfunction-associated steatotic liver disease (MASLD) pathogenesis, yet, associated functional mechanisms and host responses of specific microbial species remain insufficiently characterized. This study investigated the Bacteroides eggerthii therapeutic effects on MASLD by integrating multi-omics analysis and experimental validation in a Western diet (WD)-induced mouse model.
methodsCandidate strains were identified using 16S rRNA gene sequencing of fecal samples from individuals with and without MASLD or obesity. B. eggerthii, a species significantly depleted in both groups, was selected for functional evaluation. Male C57BL/6J mice were fed a WD or WD supplemented with B. eggerthii (WD+B) for 12 weeks. Liver histology, serum biochemistry, fecal microbiome and metabolome profiling, and hepatic and intestinal transcriptomic analyses were performed. Anti-steatotic effects of B. eggerthii-derived metabolites were validated in vitro.
resultsBacteroides eggerthii supplementation significantly improved liver weight, inflammation, fibrosis, and steatosis in WD+B group compared to WD alone. PICRUSt-based LEfSe analysis revealed choloylglycine hydrolase activity enrichment in gut microbiota, and strain-specific qPCR confirmed colonization in mouse colon. Integrated transcriptomic analyses revealed lipid and bile acid signaling pathway restoration, including CD36, FXR, and FGF15. Untargeted metabolomics identified elevated 2-hydroxyisocaproic acid (HICA) as a strain-derived metabolite in feces and B. eggerthii culture supernatants. In vitro, HICA significantly reduced lipid accumulation in free fatty acid-induced steatosis models.
conclusionsBacteroides eggerthii ameliorates MASLD via gut-liver axis modulation, including bile acid metabolism and hepatic lipid signaling. These underscore its therapeutic potential and highlight HICA as a novel microbiome-derived metabolite with anti-steatotic activity.
