Background: (MAB) has emerged as the predominant pulmonary non-tuberculous mycobacterial pathogen in parts of Asia, including Taiwan. The reasons for the significant increase in MAB infections in the non-cystic fibrosis (CF) populations are poorly understood. The study aimed to elucidate whether this increase is related to the spread of the globally successful clone of MAB.

Outbreaks of infections by , particularly subspecies , are increasingly reported worldwide. Several multilocus sequence typing (MLST) protocols for grouping international outbreak strains have been developed but not yet directly compared. Using the three-gene (, , and ), seven-gene (, , , , , , and ) and thirteen-gene (all of the preceding genes plus , , and ) MLST schemes, we identified 22, 38, and 40 unique sequence types (STs), respectively, among a total of 139 nonduplicated isolates.

Infections caused by the difficult-to-treat bacterium are increasing in frequency. Rifabutin, in contrast to rifampin, appears to be active against , especially against clarithromycin-resistant strains. However, explorations for potential synergy between rifabutin and available antimicrobials are currently limited.
