ABSTRACT
The development of reduced vancomycin susceptibility in Staphylococcus aureus in many cases appears to be associated with characteristic changes. These changes may have pitfall of identifying S. aureus by automated testing methods like Vitek 32. In this study, we retested 24 heterogeneous vancomycin-intermediate Staphylococcus haemolyticus (h-VISH) collected in 2008-2010 at the Department of Clinical Microbiology by conventional biochemical tests and polymerase chain reaction (PCR). The heterogeneous vancomycin-intermediate S. aureus (hVISA) reversion test and electron microscopic examination were also used. Six isolates of 24 h-VISH possessed nuc, coa, and 16S rRNA genes, and could be reversed into S. aureus. It suggested that biochemical and morphological changes in hVISA and vancomycin-intermediate S. aureus (VISA) should be considered, and the detection of S. aureus, especially reduced vancomycin susceptibility isolates, requires more attention and different techniques.
