A poo transplant could cure bowel infections.
A study found that implanting faeces from a healthy mouse into a sick animal's bum wiped out the illness.
Chair of Microbial Biology and Metagenomics at the University of Queensland, Mark Morrison, told Science Alert: ''Using a dose of other gut microbes through faecal transplantation appears to effectively displace these antibiotic resistant microbes, which warrants further investigation.''
Belly bugs treated by this method had previously resisted traditional treatments like drugs but more research is needed before the method can be used on humans.
