We’ve all heard about superbugs, bacterial infections that don’t respond to antibiotic treatment and wondered what’s going on.
When someone falls ill with one of these infections doctors determine which antibiotic to use based on a standard test. But UC Santa Barbara biologist Michael Moore says we may be relying on the wrong test when identifying the antibiotic to treat an infected patient.
The current test was developed in 1961 and is used throughout the world but it’s based on how well drugs kill bacteria on petri plates — not how well they kill bacteria in the body. Moore’s lab has developed a new test that mimics conditions in the body, potentially transforming the way antibiotics are developed, tested and prescribed.
His lab has identified antibiotics that effectively treat infections caused by diverse bacteria, including MRSA, the cause of deadly Staphylococcal infections. These antibiotics are often not prescribed because they failed the standard tests, despite being inexpensive, nontoxic, widely available and often effective.
He is working to modify the existing test so that it can be widely adapted to give doctors better tools and information when battling superbugs.
Drugs that pass the standard test often fail to treat bacterial infections, whereas drugs identified by Moore’s test have been effective.
