mouse gut metagenome after fecal or cecal transplant

The objectives of this study were to document the short-term and long-term efficacy of reciprocal fecal microbiota transfer (FMT) between colonies of mice harboring well-characterized gut microbiota profiles with differing composition and richness, and to evaluate the use of different source materials in FMT, including fresh feces, frozen feces, or fresh cecal contents in the same reciprocal transfer design between colonies of mice harboring distinct microbial profiles of differing richness.
