Researchers want to understand how specific bacteria in the lungs relate to a condition called nontuberculous mycobacteria (NTM) disease, which causes lung infections and breathing problems. This study will collect samples from your airways and sputum to study the microbiome — the community of bacteria naturally living in your lungs. By comparing samples from people who have confirmed NTM infection with those who don't, scientists hope to find clues about what causes the disease and how it develops.
Currently, doctors don't fully understand why some people develop serious NTM lung infections while others don't, or what role the normal bacteria in the airway play in the disease. This research could help doctors identify who is at risk and develop better treatments in the future.

You will be asked to provide sputum samples (phlegm you cough up) and upper airway samples. Some participants may also have a bronchoscopy, a procedure where doctors gently pass a thin camera down into your lungs to collect additional samples. The study involves one or more visits to NYU Langone Health, and researchers will ask you questions about your symptoms and medical history. The entire study is observational, meaning you are not taking any new medication — researchers are simply collecting and studying samples to understand the disease better.
