Effects of Short-Chain Fatty Acid Combinations Relevant to the Healthy and Dysbiotic Gut upon Candida albicans.

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
The major fungal pathogen, Candida albicans, exists as a commensal in the gastrointestinal tract of healthy humans. Fungal colonisation levels increase during gut dysbiosis, when the local microbiota and short-chain fatty acid (SCFA) concentrations become perturbed. Individually, acetic, propionic and butyric acids are reported to exert differential effects on C. albicans. In this study, we tested whether combinations of these SCFAs, at concentrations that broadly reflect healthy and dysbiotic gut profiles, influence virulence-related phenotypes. The selected healthy and dysbiotic SCFA mixes slowed the growth of C. albicans SC5314, increased resistance to cell wall stresses (Calcofluor White, SDS, caspofungin), differentially affected the exposure of the key cell surface pathogen-associated molecular patterns (PAMPs) β-1,3-glucan, chitin and mannan, and influenced total chitin content compared with non-SCFA controls. However, few differences were observed between the healthy and dysbiotic mixes. Furthermore, comparison of isolates from other epidemiological clades revealed that most effects of the SCFA mixes were strain-specific, reflecting the high degree of phenotypic variation reported previously between clinical isolates. Interestingly, the healthy SCFA mix inhibited hyphal development to a greater extent than the dysbiotic mix in some C. albicans isolates including SC5314. This was not reflected in differential adhesion to Caco-2 cells or in altered virulence in the Galleria model of systemic candidiasis. We conclude that SCFA mixtures reflecting those present in the human gut subtly influence some virulence-related phenotypes in C. albicans in a strain-specific manner.
