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

Chlamydia trachomatis and Candida albicans are common inhabitants of the female genital tract. Candida albicans can impact the viability and pathogenesis of some bacteria. Previously, we investigated physical interactions between Ch. trachomatis elementary bodies (EBs) and Ca. albicans. This work indicated that EBs bind to Ca. albicans and become noninfectious by 24 h post-binding. Here, we continue our investigation of these interkingdom, polymicrobial interactions. Candida albicans adheres to bacteria or host surfaces via agglutinin-like sequence or heat shock 70 (Ssa) proteins. Chlamydia trachomatis EBs did not bind Ca. albicans Ssa2 deficient strains as efficiently as wild-type or complemented strains, indicating a role for this protein in chlamydial adherence to Candida. Additionally, Ca. albicans β-glucans inhibit chlamydial infection when exposure occurs during EB adsorption onto cervical cells. Laminarin, a β-glucan agonist of the C-type lectin receptor Dectin-1, inhibited chlamydial infection in both cervical epithelial cells and mice when exposure occurred prior to, during, or immediately following EB inoculation. Conversely, a Dectin-1 antagonist laminarin did not inhibit infection in vitro, suggesting that β-glucan inhibition of Ch. trachomatis requires C-type lectin receptor signaling. Overall, our data demonstrate that β-glucans from multiple species, including Ca. albicans, inhibit Chlamydia via stimulation of host-signaling pathways.
