Multifocal joint infection caused by Enterococcus gallinarum.

Musculoskeletal infections caused by Enterococcus gallinarum are rare, but due to its multi-drug resistance has gained more and more attention from the scientific community. We report a case of a 81-year-old immunocompetent Caucasian female with a multifocal joint infection caused by this agent. Shoulder arthrocentesis and two different blood cultures were used to identify this vancomycin-resistant agent in a symptomatic patient. After surgical debridement and 8 weeks of antibiotherapy with ampicillin (1000 mg IV every 6 h), the clinical and laboratory findings were all remarkably improved after treatment. After 2 years follow-up, the patient had no recurrence.
