Mycobacterium sherrisii isolation from a patient with pulmonary disease.

The characterization of 2 clinical isolates of Mycobacterium sherrisii provides further phenotypic and genotypic information beyond that reported in the article that originally described this species. One of our strains was responsible for pulmonary disease in a middle-aged non-HIV patient; thus, confirming the potential pathogenicity of this species previously reported only in an HIV-positive patient.
