"Performing the transplant
The problem with C. difficile is that patients will have multiple bouts of watery and even bloody diarrhoea every day, tummy cramps, fever and in the most severe cases the infection is fatal.
The best that medicine has to offer is more antibiotics; it is the definition of a vicious circle.
A stool transplant - or to give it its full title "a faecal microbiota transplant" - aims to repopulate the patient's gut with the microbes from a healthy person.
A relative is often used as they would have had similar gut bacteria.
After a "sample" is produced, it is mixed with water.
Some techniques break the poo up by hand while others blitz it in a household blender.
There are two routes for getting the sample into the required location - down through the mouth or up through the rectum."

"But will trans-poo-sions mean anything for medicine beyond C. difficile?
The interaction between our human and microbial selves is being investigated in nearly every disease you can think of.
The microbiome has been linked to diseases including inflammatory bowel disease, diabetes, Parkinson's, whether cancer drugs work and even depression and autism.
But this means there could be unintended consequences of a faecal transplant.
There was a report in 2015 of a woman gaining 36lb (16kg) and being classed as obese after a transplant from her daughter.
It is possible to make mice thinner or fatter by transplanting into them the microbiome from either a lean or obese human, although the jury is still out on whether the same rules apply in people."
