Comparison of the BD Phoenix System with the Cefoxitin Disk Diffusion Test for Detection of Methicillin Resistance in Staphylococcus aureus and Coagulase-Negative Staphylococci

摘要

The BD Phoenix system was compared to the cefoxitin disk diffusion test for detection of methicillin (meticillin) resistance in 1,066 Staphylococcus aureus and 1,121 coagulase-negative staphylococcus (CoNS) clinical isolates. The sensitivity for Phoenix was 100%. The specificities were 99.86% for S. aureus and 88.4% for CoNS.
