Abstract

BACKGROUND: Accumulating evidence suggests that commensal bacteria consumption has the potential to have a positive impact on stress-related psychiatric disorders. However, the specific bacteria influencing behaviors related to anxiety and depression remain unclear. To this end, we compared the effects of two different Bifidobacteria on anxiety and depression-like behavior; an antidepressant was also used as a comparator. METHODS: Innately anxious BALB/c mice received daily Bifidobacterium longum (B.) 1714, B. breve 1205, the antidepressant escitalopram or vehicle treatment for 6 weeks. Behavior was assessed in stress-induced hyperthermia test, marble burying, elevated plus maze, open field, tail suspension test, and forced swim test. Physiological responses to acute stress were also assessed. KEY RESULTS: Both Bifidobacteria and escitalopram reduced anxiety in the marble burying test; however, only B. longum 1714 decreased stress-induced hyperthermia. B. breve 1205 induced lower anxiety in the elevated plus maze whereas B. longum 1714 induced antidepressant-like behavior in the tail suspension test. However, there was no difference in corticosterone levels between groups. CONCLUSIONS & INFERENCES: These data show that these two Bifidobacteria strains reduced anxiety in an anxious mouse strain. These results also suggest that each bacterial strain has intrinsic effects and may be beneficially specific for a given disorder. These findings strengthen the role of gut microbiota supplementation as psychobiotic-based strategies for stress-related brain-gut axis disorders, opening new avenues in the field of neurogastroenterology.

  • Probiotic treatment with selective Bifidobacterium strains in healthy mice can selectively improve object recognition memory, decrease the number of errors in a spatial memory test, and induce better long-term learning in fear conditioning.

    “It has been found that probiotic treatment with selective Bifidobacterium strains in healthy mice can selectively improve object recognition memory, decrease the number of errors in a spatial memory test, and induce better long-term learning in fear conditioning (Savignac et al., 2014)”

  • Preclinical behavioral screening platforms are most frequently used to identify candidate psychobiotics for further evaluation in clinical platforms.

    “Currently, preclinical behavioral screening platforms are most frequently used to identify candidate psychobiotics for further evaluation in clinical platforms (Bravo et al., 2011;Savignac et al., 2014Savignac et al., , 2015;;Burokas et al., 2017).”

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.
