Abstract

The aim of this study was to compare the antagonistic properties of Lactobacillus casei GG exerted in vitro against Salmonella typhimurium C5 in a cellular model, cultured enterocyte-like Caco-2 cells, to those exerted in vivo in an animal model, C3H/He/Oujco mice. Our results show that a 1-h contact between the invading strain C5 and either the culture or the supernatant of L. casei GG impeded the invasion by the Salmonella strain in Caco-2 cells, without modifying the viability of the strain. After neutralization at pH 7, no inhibition of the invasion by C5 was observed. The antagonistic activity of L. casei GG was examined in C3H/He/Oujco mice orally infected with C5 as follows: (i) L. casei GG was given daily to conventional animals as a probiotic, and (ii) it was given once to germ-free animals in order to study the effect of the population of L. casei GG established in the different segments of the gut. In vivo experiments show that after a single challenge with C5, this strain survives and persists at a higher level in the feces of the untreated conventional mice than in those of the treated group. In L. casei GG germ-free mice, establishment of L. casei GG in the gut significantly delayed the occurrence of 100% mortality of the animals (15 days after C5 challenge versus 9 days in germ-free mice [P < 0.01]). Cecal colonization level and translocation rate of C5 to the mesenteric lymph nodes, spleen, and liver were significantly reduced during the first 2 days post-C5 challenge, although the L. casei GG population level in the gut dramatically decreased in these animals.

  • The survival of probiotic bacteria in gastrointestinal ecosystems and their adhesion to intestinal mucosa are preconditions for temporary colonization, stimulation of the immune system, and resistance to intestinal pathogens.

    “The survival of probiotic bacteria in gastrointestinal ecosystems and their adhesion to intestinal mucosa is considered to be preconditions for temporary colonization, stimulation of the immune system, and resistance to intestinal pathogens (Hudault et al., 1997; Roselli et al., 2005).”

    The Abstract (article pp. 513–518) reports that L. casei GG established in the gut of germ-free mice and reduced the severity of Salmonella infection, supporting the colonization and pathogen-resistance aspects. It does not establish that gastrointestinal survival or adhesion to intestinal mucosa are preconditions for those effects, or link them to immune stimulation. (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.
