Performance of CHROMagar MRSA medium for detection of methicillin-resistant Staphylococcus aureus

J Clin Microbiol. 2005 Apr;43(4):1925-7. doi: 10.1128/JCM.43.4.1925-1927.2005.

Abstract

CHROMagar MRSA was evaluated for its ability to identify methicillin-resistant Staphylococcus aureus (MRSA). A well-defined collection consisting of 216 MRSA strains and 241 methicillin-susceptible Staphylococcus aureus isolates was used. The sensitivity of CHROMagar MRSA after 24 h of incubation was 95.4%, increasing to 100% after 48 h. The specificity was already 100% after 24 h.
