Abstract:
We present a case of urinary tract infection caused by vancomycin-resistant Enterococcus faecalis. The patient is a 62-year-old woman showing no recent admittances. The isolated microorganism was identified by MicroScan (DADE) and API (BioMerieux) and susceptibility was assessed by disk diffusion, E-test and broth microdilution. The isolate was identified as Enterococcus faecalis and showed high MIC for vancomycin (>128 mg/l) and teicoplanin (8 mg/l) but was susceptible to ampicillin. The transmission routes of vancomycin-resistant enterococci in the community and their clinical implications remain uncertain. Healthy carriers have already been described in several countries but this case report represents an unusual finding.
