Both diseased and healthy lungs contain genes associated with antibiotic resistance

A new study from the University of Bergen shows that genes responsible for antibiotic resistance are present not only in individuals with lung disease, but also in people with healthy lungs. The researchers examined patients with COPD, asthma, pulmonary fibrosis (IPF), and sarcoidosis, and compared them with healthy individuals. The results, now published in BMJ Open Respiratory Research, show that antibiotic resistance genes were present in all groups.
