1 · What the graph read from it

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.

2 · The registry

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

To successfully propagate and cause disease, pathogenic bacteria must modulate their transcriptional activities in response to pressures exerted by the host immune system, including secreted immunoglobulins such as secretory IgA (S-IgA), which can bind and agglutinate bacteria. Here, we present a previously undescribed flow cytometry-based screening method to identify bacterial genes expressed in vitro and repressed during infections of Vibrio cholerae, an aquatic Gram-negative bacterium responsible for the severe diarrheal disease cholera. We identified a type IV mannose-sensitive hemagglutinin (MSHA) pilus that is repressed specifically in vivo. We showed that bacteria that failed to turn off MSHA biosynthesis were unable to colonize the intestines of infant mice in the presence of S-IgA. We also found that V. cholerae bound S-IgA in an MSHA-dependent and mannose-sensitive fashion and that binding of S-IgA prevented bacteria from penetrating mucus barriers and attaching to the surface of epithelial cells. The ability of V. cholerae to evade the non-antigen-specific binding of S-IgA by down-regulating a surface adhesin represents a previously undescribed mechanism of immune evasion in pathogenic bacteria. In addition, we found that repression of MSHA was mediated by the key virulence transcription factor ToxT, indicating that V. cholerae is able to coordinate both virulence gene activation and repression to evade host defenses and successfully colonize intestines.
