We are slowly running out of ammunition to fight antibiotic resistant bacteria. Listener Peter wants to know whether a therapy that he’d heard about in the 1980s could be revived to help us where antibiotics falls short.

CrowdScience travels to Georgia where “phages”, viruses that hunt and kill bacteria, have been used for nearly 100 years to treat illnesses ranging from a sore throat to cholera. Phages are fussy eaters – a specific phage will happily chew on one bug but ignore another. In Georgia, scientists have kept rare phages safe for decades and are constantly on the look-out for new ones.

CrowdScience presenter Marnie Chesterton speaks to the scientists and doctors who are pioneering phage-therapy as well as overseas patients who have travelled thousands of miles in hope of finding a cure.
