Abstract

Background: An alternative approach for managing Candida infections in the oral cavity by modulating the oral microbiota with probiotic bacteria has been proposed.Objective: The aim was to investigate the antifungal potential of the probiotic bacterium Lactobacillus reuteri (DSM 17938 and ATCC PTA 5289) against six oral Candida species (C. albicans, C. glabrata, C. krusei, C. tropicalis, C. dubliniensis, and C. parapsilosis). Design: The lactobacilli were tested for their ability to co-aggregate with and inhibit the growth of the yeasts assessed by spectrophotometry and the agar overlay inhibition assay. Additionally, the pH was evaluated with microsensors, and the production of hydrogen peroxide (H2O2) by the lactobacilli was verified.Results: Both L. reuteri strains showed co-aggregation abilities with the yeasts. The lactobacilli almost completely inhibited the growth of C. albicans and C. parapsilosis, but did not affect C. krusei. Statistically significant differences in co-aggregation and growth inhibition capacities between the two L. reuteri strains were observed (p<0.001). The pH measurements suggested that C. krusei can resist the acids produced by the lactobacilli.Conclusions: L. reuteri exhibited antifungal properties against five of the six most common oral Candida species. Further, the results reconfirms that the probiotic capacity of L. reuteri is strain specific.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Most studies have only examined intestinal and vaginal probiotic Lactobacillus strains, and there have been very few studies relating to oral probiotic strains.

    “however, most studies have only examined intestinal and vaginal probiotic Lactobacillus strains.7, 8, 9 There have been very few studies relating to oral probiotic strains.10”

    From Aggregation and adhesion ability of various probiotic strains and Candida species: An in vitro study (2024) · cites this paper as [10]

    The paper’s introductory text (indexed under Abstract; page not provided) says that only a few studies had examined the antifungal effects of probiotic lactobacilli on non-albicans Candida species found in the oral cavity. That supports a narrower research gap, not the broader claim that very few studies concern oral probiotic strains generally. The citation is attached to the second sentence, so the separate claim about intestinal and vaginal strains is not assessed here. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
