A probe for the detection of methicillin-resistantStaphylococcus aureus

Abstract
An approximately 300 base pair DNA fragment for use as a probe was isolated from methicillin-resistantStaphylococcus aureus DNA partially digested withSau3AI. This probe hybridized with 25 methicillin-resistant clinical isolates ofStaphylococcus aureus belonging to 18 different phage types, but not with 41 clinical isolates susceptible to methicillin.
