Mycobacterium wolinskyi: a case series and review of the literature.

Mycobacterium wolinskyi is an uncommonly encountered rapidly growing mycobacterium. To date, only 12 clinical cases have been reported in the literature. In this report, we describe 5 additional cases of M. wolinskyi infection seen at the Mayo Clinic in Rochester, MN, since 2009. The clinical manifestations were sternal wound infections (n = 2), a surgical site wound infection, a cardiac-device pocket site infection, and a vascular graft infection with bacteremia. The infections occurred in both immunocompetent and immunosuppressed patients, including a lung transplant recipient. Treatment of M. wolinskyi infections required a prolonged course of combination antimicrobial treatment and surgical debridement.
