The use of laboratory susceptibility test results to guide treatment of infections with Mycobacterum abscessus and other non-tuberculous mycobacteria

In an effort to improve therapeutic options for treatment, this study will explore the use of research laboratory testing results to guide treatment decisions for difficult to treat Mycobacterium abscessus and other non-tuberculous mycobacteria (NTM) infections. Specific combinations of antibiotics will be tested in the laboratory, alone or in combination, to determine if those antibiotics could help with treatment of individual patients.
