Resumen: Objectives. The main objective of our investigation was to know the incidence and epidemiology of non-tuberculous mycobacteria (NTM) in our area and the prevalence of comorbidities in patients with MNT infection. As secondary objectives, we studied the distribution by species of MNT, the forms of disease and the type of sample used for its diagnosis. Material and methods. A retrospective study was carried out in which all the isolates of mycobacteria carried out by the microbiology laboratory of the Hospital Clínico Universitario Lozano Blesa of Zaragoza during the period between January 1, 2011 and December 31, 2018 were included. Results. A total of 533 mycobacteria were isolated, of which 295 (55.35%) were tuberculosis (MTB) and 238 (44.65%) were MNT. Of the whole MNT isolates, only 15.54% were considered clinically significant. Twenty-one species were identified being the most frequent: M. gordonae (26.89%), M. fortuitum (19.75%) and M. avium (16.39%). 32.72% of the MNT isolates were found in people over 70 years of age. Conclusions. We can confirm that the reported number of MNT isolates in our area is higher than in previous periods. MNT infection is more common in men and those older than 70 years. The epidemiology, especially the risk factors, of MNT disease is changing.
