Looking for a new way to treat drug-resistant disease

This is Science Today. One of the major health problems that have grown in recent times is multi-drug resistance, in which a disease-causing organism cannot be treated with drugs or chemicals. Gerry McDermott, a research biophysicist at the University of California, San Francisco says this includes methicillin-resistant staphylococcus aureus, or MRSA. 

McDermott:   MRSA, methicillin-resistant strains of bacteria are one of the major causes of infections in hospitals. They're also incredibly difficult to treat. They're resistant to at least two or three antibiotics.

Narrator:       McDermott is part of a team of researchers working with peptoids, which are chemically similar to peptides, but they are more stable and bacteria and fungi have no drug resistance against peptoids compared to conventional antibiotics.

McDermott:   What we've been looking at in the future is treating various types of bacterial and fungi with peptoid molecules. So, the development of peptoids as antimicrobials and antifungal agents overcomes a huge amount of drug resistance-related problems, particularly in hospitals.
