Cystic Fibrosis Patients Have More Bacteria—Good and Bad—In the Lungs

The role of antibiotics

In healthy lungs, when antibiotics are prescribed to individuals with advanced infections, the microbiome is strongly affected. Bacteria count and diversity are both lowered, although once a person is taken off of antibiotics, the microbiome generally returns to a state of equilibrium. The difficulty in this process is that even though the microbiome returns to a state of equilibrium, it does not return to the exact same state with the exact same configuration that it was in before treatment.
