Evaluation of resazurin microplate method for rapid detection of vancomycin and linezolid resistance in Enterococcus faecalis and Enterococcus faecium clinical isolates.

RMM had a good positive predictive value for the detection of vancomycin-non-susceptible E. faecium and linezolid-non-susceptible E. faecalis. It thus has the potential to become an alternative method for the rapid screening of these resistant pathogens in clinical practice.
