First Case of VRSA Identified in Michigan

Abstract

In June 2002, the first clinical isolate of Staphylococcus aureus fully resistant to vancomycin was obtained from the tip and the exit site of a catheter of a Michigan resident with chronic renal failure who received dialysis. 1 Previously, in Michigan and elsewhere, vancomycin-intermediate S. aureus had been recovered in a similar clinical setting of long-term hemodialysis. Similar to previously described cases of glycopeptide-intermediate S. aureus (GISA), the current patient had been recently treated with vancomycin for a bloodstream infection with methicillinresistant S. aureus (MRSA). In addition, the patient had diabetes mellitus and a chronic diabetic foot ulcer.
