Abstract:
Mycobacterium simiae is an ubiquitous species rarely involved as a cause of human infection. Its pathogenicity remains therefore unclear and controversial. Disseminated infections with M. simiae occur rarely and only 7 cases have been reported in patients with acquired immunodeficiency syndrome (AIDS). At least, two were mixed infections caused by M. simiae and M. avium-intracellulare. We report the case of two AIDS patients presenting with pure M. simiae infections: one was a disseminated infection and the other a pulmonary infection. Epidemiology and pathogenicity of M. simiae in pulmonary, extra-pulmonary and disseminated infections are reviewed.
