First of its kind ‘living medicine’ designed to treat antibiotic-resistant bacteria on medical implants

Researchers at the Centre for Genomic Regulation and Pulmobiotics S.L have created the first 'living medicine' to treat antibiotic-resistant bacteria growing on the surfaces of medical implants. The researchers created the treatment by removing a common bacteria's ability to cause disease and repurposing it to attack harmful microbes instead.
