Researchers in the US have found a way to target and kill antibiotic resistant bacteria using a drug that is already approved as a treatment for bone loss.

Bacteria are in the habit of giving each other strands of DNA; this is how they pass on survival advantage, including resistance to antibiotics. An enzyme called relaxase helps them do this. Bisphosphates, which are used to treat bone loss, appear to disrupt the process and prevent the transfer of antibiotic resistance genes, and selectively cause the death of resistant bacteria.
