A review of engraftment assessments following fecal microbiota transplant

examines how resistant post-FMT recipients' microbiomes are to reverting back to baseline. These concepts explore subtly different questions about the microbiome following FMT. Taken together, they provide holistic insight into how an FMT alters a recipient's microbiome composition and provide a clear framework for quantifying and communicating about microbiome engraftment.
