By means of a DNA probe assay (INNO-LiPA) we identified 2 different mycobacterial strains (Mycobacterium avium and Mycobacterium tuberculosis complex) from a mediastinal lymph node biopsy obtained from an apparently immunocompetent 7.5-year-old girl, whereas culture grew only M. avium. Clinicians should be aware of the possible occurrence of mixed infection involving both nontuberculous mycobacteria and M. tuberculosis.
