The research leader, Frances Separovic, a biophysical biologist, said most antimicrobial peptides killed bacteria by puncturing or lysing (causing them to disintegrate) their membranes. This made it hard for bacteria to develop resistance to them..'On the other hand, most antibiotics inhibit protein synthesis in a bacteria and, over time, mutations in the bacteria lead to resistance to the antibiotics,''
