Cutaneous Mycobacterium thermoresistibile Infection in a Heart Transplant Recipient

Abstract

A cutaneous infection by Mycobacterium thermoresistibile occurred 3 months after cardiac transplantation near the surgical scar in a diabetic patient. The organism's growth and biochemical characteristics are described, along with extensive susceptibility data. Only two previous human infections with this organism have been reported, both pulmonary. Response to oral rifampin, ethambutol, and isoniazid was complete but slow, although the organism was isoniazid-resistant.
