Synergy between Lactobacillus paracasei and its bacterial products to counteract stress-induced gut permeability and sensitivity increase in rats
Open accessAbstract
Stressful events result in the alteration of gut permeability and sensitivity. Lactobacillus paracasei NCC2461 (Lpa) therapy prevents antibiotic-induced visceral hyperalgesia in mice. This study aimed at evaluating the influence of 3 probiotic strains: Bifidobacterium lactis NCC362, Lactobacillus johnsonii NCC533, and Lpa on stress-mediated alterations of colorectal hyperalgesia, on gut paracellular permeability and whether bacteria and/or bacterial products present in the spent culture medium (SCM) were involved in the antinociceptive properties of the effective strain. Rat pups were separated from their mothers 3 h/d during postnatal d 2-14. At wk 13, gut paracellular permeability was determined as a percentage of urinary excreted (51)Cr-EDTA and visceral sensitivity to colorectal distension (CRD), assessed by abdominal muscle electromyography. Visceral sensitivity was also analyzed in adults rats subjected to partial restraint stress (PRS, 2 h restriction of body movements). Rats received either the probiotics resuspended in SCM or fresh growth medium as control for 2 wk. Maternal deprivation significantly increased colonic sensitivity in response to CRD and enhanced gut paracellular permeability compared with control rats. Only Lpa treatment significantly improved stress-induced visceral pain and restored normal gut permeability. Similarly, among the 3 probiotics tested, only Lpa prevented PRS-mediated visceral hyperalgesia. Both bacteria and bacterial products present in Lpa SCM were required for the antinociceptive properties against PRS. This study illustrates strain-specific effects and suggests a synergistic interplay between L. paracasei bacteria and bacterial products generated during fermentation and growth that confers the ability to suppress PRS-induced hypersensitivity in rats.

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.
