Typhoid toxin causes neuropathology by disrupting the blood-brain barrier.
Article in Nature microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Typhoid fever, primarily caused by Salmonella Typhi, can result in severe life-threatening complications such as encephalopathy. Here we elucidate the mechanisms by which typhoid toxin, a unique virulence factor of S. Typhi, mediates the neuropathology associated with typhoid fever. Utilizing mice engineered to have specific tissues protected from toxin action and an in vitro model of the blood-brain barrier (BBB), we demonstrate that, rather than direct action on neuronal or glial cells, typhoid toxin causes neuropathology by disrupting the BBB. Intravenous tracer studies confirmed significant BBB permeability changes following toxin exposure, an effect we found to be mediated by typhoid toxin's CdtB catalytic subunit. We demonstrate that corticosteroids are effective at mitigating BBB disruption in vivo, supporting their use for managing typhoid fever neurological complications. Our data reveal mechanistic insight into how typhoid toxin causes encephalopathy and suggest targeted therapeutic interventions to alleviate the severe neurological manifestations of typhoid fever.
