This research examines the effects of age-associated Bifidobacterium on gut immunity and microbial diversity.
Utilized short-term interventions (2 weeks) with Bifidobacterium strains (BA and BI).
Assessed colorectal length and intestinal crypt recovery.
Conducted H&E staining to evaluate intestinal barrier integrity and immune cell infiltration.
Short-term Bifidobacterium interventions did not change colorectal length.
Both BA and BI treatments promoted recovery of damaged intestinal crypts.
Interventions enhanced intestinal barrier integrity and reduced immune cell infiltration.
