Membership robustness but structural change of the native gut microbiota of bumble bees upon systemic immune induction.

Unlabelled: Understanding factors influencing the composition and maintenance of beneficial host-associated microbial communities is central to understanding their ecological, evolutionary, and health consequences for hosts. Host immunity is often implicated as a regulator of these microbiota, but immunity may also play a disruptive role, with responses to infection perturbing beneficial communities. Such effects may be more prominent from innate immune responses, with more rapid-acting and often non-specific components, compared to adaptive responses.
