Abstract

Mycobacterium abscessus lung infections remain difficult to treat. Recent studies have recognized the power of new combinations of antibiotics, such as bedaquiline and imipenem, although in vitro data have questioned this combination. We report that the efficacy of bedaquiline-imipenem combination treatment relies essentially on the activity of bedaquiline in a C3HeB/FeJ mice model of infection with a rough variant of M. abscessus The addition of imipenem contributed to clearing the infection in the spleen.

Keywords: C3HeB/FeJ mice; Mycobacterium abscessus; bedaquiline; cystic fibrosis; imipenem.
