Abstract

Mycobacterium abscessus is an emerging nontuberculous mycobacterium (NTM) pathogen infecting susceptible people with cystic fibrosis (CF) and non-CF bronchiectasis. Here, we demonstrated the activity of an FDA-approved drug, disulfiram, against drug-susceptible and drug-resistant M. abscessus strains utilizing in vitro and intracellular macrophage assays and a zebrafish embryo infection model. These data demonstrate effective antimicrobial activity of disulfiram against M. abscessus infection in vivo and strongly support further study of disulfiram in human NTM infections.
