Incidence of tuberculous and non-tuberculous mycobacteria, differentiated by multiplex PCR, in clinical specimens of a large general hospital

Abstract

Several non-tuberculous mycobacterial species were identified, primarily M. avium, but other potentially pathogenic species were also frequently observed, including M. fortuitum, M. abscessus, and M. kansasii. The expeditious communication of these data to the clinical staff was fundamental for the diagnosis of clinical cases. Even in settings where tuberculosis is of major importance, the incidence of non-tuberculous mycobacteria infection is substantial.
