Abstract

It's difficult to prove exactly when and how people with bronchiectasis acquire NTM from the environment. We present data showing long-term household exposures of a homeowner and development of NTM pulmonary disease following the onset of bronchiectasis and correlating disease onset with longitudinal environmental sampling in an NTM geographic hotspot.
