Bacillus velezensis DSM 33864 reduces Clostridioides difficile colonization without disturbing commensal gut microbiota composition.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Up to 25% of the US population harbor Clostridioides difficile in the gut. Following antibiotic disruption of the gut microbiota, C. difficile can act as an opportunistic pathogen and induce potentially lethal infections. Consequently, reducing the colonization of C. difficile in at-risk populations is warranted, prompting us to identify and characterize a probiotic candidate specifically targeting C. difficile colonization. We identified Bacillus velezensis DSM 33864 as a promising strain to reduce C. difficile levels in vitro. We further investigated the effects of B. velezensis DSM 33864 in an assay including human fecal medium and in healthy or clindamycin-treated mouse models of C. difficile colonization. The addition of B. velezensis DSM 33864 to human fecal samples was shown to reduce the colonization of C. difficile in vitro. This was supported in vivo where orally administered B. velezensis DSM 33864 spores reduced C. difficile levels in clindamycin-treated mice. The commensal microbiota composition or post-antibiotic reconstitution was not impacted by B. velezensis DSM 33864 in human fecal samples, short-, or long-term administration in mice. In conclusion, oral administration of B. velezensis DSM 33864 specifically reduced C. difficile colonization in vitro and in vivo without adversely impacting the commensal gut microbiota composition.
