Mycobacterium avium-M. intracellulare isolates from patients with or without acquired immunodeficiency syndrome

Abstract
Susceptibility testing and serotyping were performed on 57 isolates of Mycobacterium avium-M. intracellulare from patients with acquired immunodeficiency syndrome (AIDS) and 75 isolates from patients without AIDS. Susceptibility patterns and serotypes of AIDS isolates were significantly different from those of non-AIDS isolates. These results may partially explain the poor therapeutic response of M. avium-M. intracellulare infections in AIDS patients.
