NICE recommends transplant with good bacteria taken from poo to resolve recurrent Clostridium difficile infections: experts estimate that 450 to 500 people could be treated using FMT for multiple recurrences of C. diff infections each year. Hundreds of people with recurrent bacterial infections could be treated with gut bacteria taken from a healthy donor’s poo. NICE has recommended a faecal microbiota transplant (FMT) is offered to people who have been treated for two or more Clostridium difficile (C. diff) infections without success.
