Hope for fighting antibiotic resistant bacteria

One of the things that really scares doctors is antibiotic resistant bacteria. There is a version of tuberculosis that is immune from all of the drugs we normally would use; if you get it, doctors can’t do anything to fight it. This happens because some bacteria are naturally more resistant than others. Over time, these manage to survive better because they aren’t killed by antibiotics as quickly. This is evolution by natural selection. About 2/3 of bacteria form biofilms. Researchers have found a peptide that can destroy biofilms or stop them from forming. This can kill the bacteria. Hopefully this will give us a good class of drugs that can kill the normally antibiotic resistant bacteria. Videos:
