Fecal transplants are experimental procedures in which physicians use a healthy donor's chair to treat a person whose own microbiome is out of whack.
The procedure has proven promising for the treatment of various health problems.
An immunocompromised patient who has received a fecal transplant for unknown reasons died after the procedure and another patient is seriously ill, causing the Food and Drug Administration to discontinue a series of fecal transplant attempts.
