Preventive and therapeutic effects of co-administration of Bacteroides thetaiotaomicron and infliximab on dextran sodium sulfate-induced colitis in mice.
Article in Intestinal research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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/
aimsThe gut microbiota plays a crucial role in the pathogenesis and treatment of inflammatory bowel diseases (IBD). This study aimed to investigate the effects of active, heat-inactivated, and cell-free supernatant (CFS) forms of Bacteroides thetaiotaomicron, alone or in combination with infliximab, in dextran sodium sulfate (DSS)-induced colitis in mice. Colitis was induced by oral administration of DSS for seven days. B. thetaiotaomicron in its various forms was orally administered at a dose of 1 × 108 CFU prior to and during colitis induction. Infliximab was intraperitoneally injected from days 3 to 5 of DSS exposure. Colitis severity, gene expression, tumor necrosis factor alpha levels, and gut microbiota were assessed by disease activity index, reverse transcription-quantitative polymerase chain reaction (RT-qPCR), enzyme-linked immunosorbent assay (ELISA), and qPCR, respectively.
resultsActive B. thetaiotaomicron and its CFS form significantly alleviated colitis symptoms compared to the heat-inactivated form. Furthermore, co-administration of active B. thetaiotaomicron and infliximab significantly modulated the colonic mRNA expression of Ocln, Tff3, Muc2 (upregulated), and Ace2 (downregulated). This combination also exhibited synergistic improvement in colitis severity in treated mice.
conclusionsThese findings underscore the therapeutic potential of B. thetaiotaomicron in IBD, either alone or in combination with infliximab, and support further development of microbiota-based strategies for IBD prevention and treatment.
