Limosilactobacillus reuteri ameliorates maternal separation stress in newborn mice and alters subsequent adult behaviour.

ABSTRACT: Maternal separation (MS) in mice results in behavioral deficits and gut microbiota dysbiosis that all persist into adulthood. Limosilactobacillus reuteri DSM 17938 modulates gut microbiota, alters systemic metabolites, and facilitates immune regulation. To assess the effect of DSM 17938 on biochemical and behavioural stress-associated changes, newborn mice were exposed to unpredictable MS (MSU) daily from day 7 to day 20 of life, with intragastric administration of DSM 17938 or PBS as control. Body weight, brain levels of cholecystokinin (CCK), glial fibrillary acidic protein (GFAP), corticosterone, and stool microbiota were assessed at day 21. Behaviour tests including Y-maze (YMT), Tail Suspension (TST), and Open Field (OFT) were evaluated in adult mice. MSU resulted in a decrease in ear
