ABSTRACTBrain heart infusion agar containing 3 mg/liter vancomycin (BHI-V3) was used to screen for heterogeneous vancomycin-intermediateStaphylococcus aureus(hVISA). There was markedly greater biofilm formation by isolates that grew on BHI-V3 than by strains that did not grow on BHI-V3. Increased biofilm formation by hVISA may be mediated by FnbA- and polysaccharide intercellular adhesin-dependent pathways, and upregulation ofatlAandsarAmay also contribute to enhanced biofilm formation by hVISA upon prolonged exposure to vancomycin.
