Vancomycin has been used successfully for over 50 years for the treatment of Staphylococcus aureus infections, particularly those involving methicillin-resistant S. aureus. It has proven remarkably reliable, but its efficacy is now being questioned with the emergence of strains of S. aureus that display heteroresistance, intermediate resistance, and, occasionally, complete vancomycin resistance. More recently, an association has been established between poor outcome and infections with strains of S. aureus with an elevated vancomycin MIC within the susceptible range. This minireview summarizes the definitions, mechanisms, clinical impact, and laboratory identification of reduced vancomycin susceptibility in S. aureus and discusses practical issues for the diagnostic laboratory in testing and interpreting vancomycin susceptibility for S. aureus infections.
