Lemur and baboon poo could treat foot ulcers in people with diabetes.
Scientists have found that viruses within the faeces of endangered animals at Yorkshire Wildlife Park could kill the bacteria within diabetic foot ulcers.
The ulcers lead to over 7,000 amputations per year but are hard to treat as the ulcers are often infected by antibiotic-resistant bacteria that prevents healing.
Boffins are yet to test the viruses on the ulcers of diabetic patients but are hopeful that the faeces can provide an important scientific breakthrough.
Professor Graham Stafford, who is leading research into viruses for the University of Sheffield, said: "We have been searching for new treatments for antibiotic resistance for a while and we are the first to look for such a virus in zoo poo.
"It's a delight that endangered species are contributing to such a positive and powerful purpose."
