Why certain lung mycobacteria resist antibiotics

Molecular mechanisms of inherent drug resistance in non-tuberculous mycobacteria

NIH-funded research Harvard University D/b/a Harvard School of Public Health · NIH-11143231

Researchers are finding ways to make the bacteria that cause long-lasting lung infections more sensitive to existing antibiotics for people with non-tuberculous mycobacterial (NTM) lung disease.

What this research studies

Researchers will use a new lab model that mimics lung infection together with genetic methods to find bacterial genes and pathways that let NTMs survive antibiotics. They will test whether targeting those genes can allow common antibiotics to stop growth or kill Mycobacterium abscessus at drug levels that are safe for patients. The team will also extend promising findings to Mycobacterium avium complex, a more common cause of human NTM infection. The work is lab-based but directed at identifying drug targets or combinations that could lead to better treatments for people with chronic NTM lung infections.

Who could benefit from this research

Good fit: People with chronic non-tuberculous mycobacterial lung infections, especially those infected with Mycobacterium abscessus or Mycobacterium avium complex, are the patient groups most likely to benefit from this line of research.

Not a fit: People without NTM infections or those seeking immediate clinical treatment are unlikely to gain direct benefit from this laboratory-focused grant.

Why it matters

Potential benefit: If successful, this work could point to ways to make existing antibiotics clear NTM infections faster and with fewer long-term toxic effects.

How similar studies have performed: Some prior laboratory studies have explored sensitizing mycobacteria to antibiotics, but this approach for NTMs is relatively new and has not yet been proven in patients.
