Detection of Methicillin-Resistant Staphylococcus aureus (MRSA) using Modified Conventional Cefoxitin-based Media as an Alternative Screening

Methicillin-resistant Staphylococcus aureus (MRSA) can cause infection with higher morbidity and mortality. In the limited-resource setting, availability of rapid detection is scarce may not be available; therefore, prompt using alternative method indispensable. To compare rate modified-conventional chromogenic media against mucocutaneous clinical swab, a total 80 S. isolates from previous studies were cultivated re-cultured into routine such as blood agar (BA) mannitol-salt (MSA) between June September 2018. It directly inoculated plain that had been incubated day before; it further underwent inoculation to other media, (CHROMagar), mannitol salt supplemented cefoxitin (CFOX) powder manually. The sensitivity MSA-CFOX BA-CFOX, respectively, was 96.88%. On hand, CHROMagar MHA-CFOX 90.62%. specificity each MHA-CFOX, MSA-CFOX, 87.5% well 93.75% for BA-CFOX. study has demonstrated better performance compared media. Hence, application modified-media should delayed facilitate findings MRSA among hospitalized patients.
