Official title: Bacteriophage interactions with nontuberculous mycobacteria in the intracellular environment of mammalian cells

Funded at Colorado State University · NIH-11439724 · Data updated 2026-11-12

This grant tests whether viruses that infect bacteria (phages) can reach and kill drug-resistant Mycobacterium abscessus inside human lung cells.

Who could benefit from this research

Could help

Patients with nontuberculous mycobacterial lung infections, especially those with Mycobacterium abscessus.

Less likely to help

People without NTM lung infections or those not affected by intracellular bacterial persistence may not benefit.

What this research studies

Researchers will study how bacteriophages interact with intracellular M. abscessus living inside mammalian cells, using models that mimic the lung environment. They will examine whether phages can enter cells, infect the bacteria, and reduce bacterial load, aiming to improve options beyond traditional antibiotics. The work focuses on optimizing phage therapy for intracellular infections in people with chronic lung diseases like bronchiectasis or COPD. Findings could guide future compassionate-use treatments and clinical development for hard-to-treat NTM lung infections.

Why it matters

Potential benefit: If successful, this approach could lead to new phage-based therapies for drug-resistant lung infections.

How similar studies have gone: Preliminary work shows phages can enter mammalian cells and kill intracellular bacteria, but results are variable and more work is needed.
