Reduced Vancomycin Susceptibility Found in Methicillin-Resistant and Methicillin-Sensitive Staphylococcus aureus Clinical Isolates in Northeast China

Abstract

The percentage of hVISA strains was high and increased each year. The proportion of hVISA among MSSA specifically also increased significantly each year. In isolates collected from diverse infection sites, hVISA and VISA strains were found predominantly in sputum, pus, and blood, in descending order. Testing for vancomycin susceptibility should include both MRSA and MSSA isolates collected from different clinical sites.
