Identification of non-tuberculous mycobacteria from clinical samples

Non-tuberculous mycobacterial infections cause morbidity worldwide. NTM are considered opportunistic pathogens, and several species have been associated with human disease which has typically pulmonary, skin and soft tissue, lymphatic or disseminated presentation. This study evaluated the distribution of non-tuberculous mycobacteria in Sardinia. Mycobacterium avium, Mycobacterium gordonae and Mycobacterium xenopi were frequently found. Our results agreed with literature data both for the frequent isolation of M. avium, M. xenopi and M. gordonae, and the symptoms and radiological evidence of the patients analysed.
