Evaluation of the BD Max StaphSR Assay for Detecting Methicillin-Resistant Staphylococcus aureus (MRSA) and Methicillin-Susceptible S. aureus (MSSA) in ESwab-Collected Wound Samples

摘要

The BD Max StaphSR assay (BD Diagnostic Systems, Québec, Canada) performed on the BD Max system (BD Diagnostic Systems, Sparks, MD) is an FDA-cleared molecular test for detection of S. aureus DNA and MRSA DNA from nasal swab specimens collected from patients at risk of infection due to nasal colonization (8, 9). The BD Max is an automated sample-in and answer-out instrument that combines sample extraction, PCR setup, and real-time PCR on a walkaway platform. This PCR-based test can provide results in approximately 2.5 h. The objective of this study was to evaluate the BD Max StaphSR assay for the detection of S. aureus and MRSA from ESwab (Copan Diagnostics, Murrieta, CA)-collected wound samples and to compare the results to culture, our standard of care procedure. ESwab-collected wound samples are not FDA cleared for use with the BD Max StaphSR assay.
