Viruses found in the poo of endangered animals could be used to treat diabetic foot ulcers and save the NHS £1 billion a year, a research team led by Professor Graham Stafford has suggested. A team from the University of Sheffield said naturally occurring viruses in the poo – known as bacteriophage or phages – could be included in dressings applied to untreatable ulcers with further research. There are thousands of different types of phages, which selectively target and kill bacteria, even in instances when antibiotics do not work. Phage therapy was first discovered in the early 20th century. The research team, led by Professor Graham Stafford, used poo from various animals, including Guinea baboons, lemurs and Visayan pigs, which are housed at Yorkshire Wildlife Park (YWP).Source: PA
