Abstract:
Bifidobacteria are widely recognized important symbionts of the human gut microbiome, shaping host physiology from birth to adulthood to old age. Their evolutionary success is derived from metabolic versatility, ecological adaptation and intimate host interactions. Equipped with an expansive glycan-degrading repertoire, stress-response systems and specialized cell surface structures, bifidobacteria establish stable gut colonization and influence host immune, metabolic and neuroendocrine functions. Genomics and functional studies have revealed how human-associated members of this genus shape trophic networks, tolerance and resilience within the gut ecosystem. Integration of ecological, metabolic and immunological perspectives now positions the genus Bifidobacterium as an excellent model to support human gut health and its potential use as gut microbiota-based therapeutics.
