Utilization of CHROMagar MRSA in the supervision of the methicillin-resistent Staphylococcus aureus

Methicillin-resistent Staphylococcus aureus (MRSA) is one of the most common pathogen responsible for nosocomial infections. Laboratory diagnosis and assays of antimicrobial susceptibility are basic in controlling and preventing infection by MRSA. Our study was conducted for one year (May 2008-April 2009) on patients hospitalized to monitor the eventual colonization by MRSA.The use of chromogenic agar MRSA allowed us to identify pink-mauve colonies of MRSA within 24 hours and to make a timely e careful diagnosis.
