The lower intestine of adult mammals is densely colonized with non-pathogenic (commensal) microbes. Gut bacteria induce protective immune responses, which ensure host-microbial mutualism. The continuous presence of commensal intestinal bacteria has made it difficult to study mucosal immune dynamics. Here we report a reversible germ-free colonization system in mice that is independent of diet or antibiotic manipulation. A slow (>14 days) onset of a long-lived (t1/2>16 weeks), highly specific anti-commensal IgA response in germ-free mice was observed. Ongoing commensal exposure in colonized mice rapidly abrogated this response. Sequential doses lacked a classical prime-boost effect seen in systemic vaccination, but specific IgA induction occurred as a stepwise response to current bacterial exposure, such that the antibody repertoire matched the existing commensal content.
