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.
我们报告一例由耐万古霉素粪肠球菌引起的尿路感染病例。患者为一名62岁女性，近期无入院史。分离出的微生物通过MicroScan（达德公司）和API（生物梅里埃公司）进行鉴定，并通过纸片扩散法、E试验和肉汤微量稀释法评估药敏性。分离菌株被鉴定为粪肠球菌，对万古霉素（>128mg/L）和替考拉宁（8mg/L）显示出高最低抑菌浓度，但对氨苄西林敏感。耐万古霉素肠球菌在社区中的传播途径及其临床意义仍不明确。几个国家已经报道过健康携带者，但本病例报告代表了一个不寻常的发现。
