Genome-resolved and culture-based atlas of the feline gut microbiome enables host-adapted probiotic development.
Article in NPJ biofilms and microbiomes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Domestic cats (Felis catus) depend on their gut microbiome for metabolism, immunity, and pathogen defense, yet its genomic characterization remains limited. We combined large-scale metagenomics and culturomics to define the feline gut microbiome and identify indigenous probiotic candidates. Analysis of 412 feline fecal metagenomes produced 2852 strain-resolved metagenome-assembled genomes (MAGs) grouped into 514 species-level genome bins, including 106 putative novel taxa. This catalog revealed 24 core species and two enterotypes: ET-P, deaminated by Prevotella, and ET-CB, enriched for Collinsella, Blautia, Bifidobacterium, Ligilactobacillus, MAG-based screening prioritized 113 candidate probiotic species. Culturomics recovered 2904 isolates representing 110 species-level taxa, including 75 putative novel species and a candidate novel genus. Six feline-derived isolates were selected for downstream testing, and five exhibited favorable probiotic traits in vitro, including acid and bile tolerance, anti-Escherichia coli activity, and favorable cytokine responses. In a pathogenic Escherichia coli-induced dirrhea model in cats, a five-strain indigenous consortium improved fecal scores and reduced IL-2, IL-1β, and IL-6, with TNF-α suppression superior to antibiotics or a commercial probiotic. These results establish FelMGDB as a resource for feline microbiome research and highlights indigenous probiotics as promising interventions for feline gut health.
