...olonization of the tissue by bacteria, such as the superbug MRSA." DLC was first produced in 1971 in a vacuum chamber using a technical and costly method that involved spraying charged carbon atoms at the surface to be coated. Subsequent techniques have improved on this. However, Franks and his colleagues hav...

Unusual antibiotics show promise against deadly 'superbugs'

...fied in the early 1960s and has become a difficult superbug to tame. While searching for strategies to defeat it, Mobasherys research group focused on an enzyme called penicillin-binding protein 2a (PBP 2a), which is unique to MRSA. Research by others showed that the enzyme, located on the bacterial cell memb...
