Table 3.
The number of pulmonary samples and patients with non-tuberculous mycobacteria (NTM) isolation for the indicated complex/species from mycobacteriological laboratories with follow-up data in 2016–2020. The number and proportion of patients meeting microbiological criteria of ATS/IDSA [5] for NTM pulmonary disease are represented of all patients with at least one laboratory-confirmed case of NTM; (1) Positive culture from two separate samples and (2) samples collected from bronchial wash or lavage (BAL) or surgical biopsy.
