We are running out of ammunition against certain infections, as bacteria increasingly evade the antibiotics we’ve relied on for nearly a century. Could bacteriophages – viruses that hunt and kill bacteria – be part of the solution?

In 2019, CrowdScience travelled to Georgia where bacteriophages, also known as phages, have been used for nearly a hundred years to treat illnesses ranging from a sore throat to cholera. Here we met the scientists who have kept rare phages safe for decades, and are constantly on the look-out for new ones. Phages are fussy eaters: a specific phage will happily chew on one bacteria but ignore another, so hunting down the right one for each infection is vital.

Since then, we’ve lived through a pandemic, the medical landscape has been transformed, and interest in bacteriophages as a treatment option is growing throughout the world. We turn to microbiologist Professor Martha Clokie for updates, including the answer to listener Garry’s question: could phages help in the fight against Covid-19?
