'Poo pill' paves the way for faecal transplants

US researchers have come up with a way of taking the 'ick' factor out of faecal transplants, which are remarkably effective in treating refractory Clostridium difficile infection.  

Using freeze-dried faecal microbiota, they have developed a capsule that can be taken orally, which could ultimately replace the uncomfortable and potentially messy techniques for faecal transplant, such as colonoscopy, enemas or nasogastric tube.

The freeze-drying technique preserves the viability of faecal mirobes and allows ease of encapsulation for transfer to the colon, according to researchers
