Safety profile and effects on the peripheral immune response of fecal microbiota transplantation in clinically healthy dogs.

Background: Fecal microbiota transplantation (FMT) is increasingly used for gastrointestinal and extra-gastrointestinal diseases in veterinary medicine. However, its effects on immune responses and possible adverse events have not been systematically investigated.

Hypothesis/objectives: Determine the short-term safety profile and changes in the peripheral immune system after a single FMT administration in healthy dogs.
