Pollen Polysaccharides Drive the Strain-Level Assembly and Competitive Dynamics of Bifidobacterium in the Honeybee Gut.
The gut microbiota orchestrates host health by influencing nutrition, immunity, and behavior. Bifidobacterium species are early colonizers maintaining gut homeostasis in honeybees. Despite these critical roles, strain-level dynamics and driving forces behind microbial competition during social transmission remain poorl...
