Nontuberculosis mycobacterium are increasingly being identified as sources of disseminated infections in immunocompromised patients. These infections can be challenging to identify and treat due complexities of diagnosis and inherent resistance to many medications. We present two cases of patients with human immunodeficiency virus who had Mycobacterium simiae infections, complicated by immune reconstruction inflammatory syndrome (IRIS). We also present a review of the English literature surrounding the disease, including reported resistance patterns to antimicrobial therapy, which can be highly variable.
