Mycobacterium shigaense infection: a case and brief literature review.

Infections due to Mycobacterium shigaense, a slow-growing mycobacterium of the Mycobacterium simiae complex, are rarely reported. We describe a case of M. shigaense infection in a 68-year-old woman with diabetes and found that its infections are often associated with immunocompromised conditions or underlying pulmonary diseases in East Asia.
