    The study introduces a novel fecal microbiota transplant (FMT) method that reduces stress in murine models compared to traditional oral gavage.

  • 2

    Mice receiving FMT via frozen aliquots showed significantly lower plasma corticosterone levels than those receiving FMT through oral gavage.

  • 3

    Microbial signatures in recipient mice were more similar to donor mice after FMT via frozen aliquots, sustaining similarity for up to six weeks.

  • 4

    The study emphasizes the need for standardized FMT protocols in murine models to enhance the validity of gut-brain axis research.

  • 5

    The research highlights the importance of minimizing treatment-induced stress to improve outcomes in studies investigating gut microbiome effects on behavior.
