    Within the past year, infections caused by methicillin-resistant Staphylococcus aureus (MRSA) strains with reduced susceptibility to vancomycin (MIC=8 mug/mL) have been reported in both Japan and the United States.

    The emergence of these strains poses a potentially serious threat to public health.

    After 2 such strains (Mu3 and Mu50) were identified at Juntendo Hospital in 1996, a screening program to identify MRSA strains with reduced susceptibility to vancomycin was initiated.

    Of 970 MRSA strains tested at 195 nonuniversity hospitals throughout Japan, 13 (1.3%) were found to have subpopulations with reduced vancomycin susceptibility (heterogeneous vancomycin resistance).

    Among 129 MRSA strains identified at 7 university hospitals, 12 (9.3%) demonstrated heterogeneity for vancomycin resistance ; 1 of these strains had a vancomycin MIC of 7 mug/mL.

    Although resistance in these strains is not the result of the transfer of enterococcal vancomycin resistance genes (vanA or vanB), the clonal dissemination of MRSA strains with vancomycin-resistant subpopulations is obviously undesirable.

    Intensified testing of MRSA strains for resistance to vancomycin and appropriate measures for the prevention of the spread of such strains are recommended.
