Results from a PERMANOVA test for the influence of sampling site (feces-start, feces-end, ileum, or ICLN), group (AB or control), and both interdependently on the differences in community structure. PERMANOVA = permutational analysis of variance; ICLN = ileocecal lymph node; AB = antibiotics; NS = Not significant.
