It is regular for folks to have fungi of their lungs, and utilizing medication like inhaled steroids will not harm them, a analysis group discovered.

In response to a group led by Einar Marius Hjellestad Martinsen, a doctoral candidate on the College of Bergen in Norway, it was lengthy thought that wholesome lungs have been sterile, with solely illnesses like persistent obstructive pulmonary illness (COPD) enabling microorganisms to enter them and survive.

Now it has been proven that a number of microorganisms reside within the lungs of wholesome folks, too.

On this examine, Norwegian researchers analyzed lung and mouth samples from almost 200 folks with and with out COPD.

“Both healthy and diseased lungs had a different fungal composition than the mouth, suggesting that lungs have a unique fungal environment,” Hjellestad Martinsen stated in a college news launch.


Candida was the dominant fungus within the lungs. Researchers discovered no variations in fungal communities between folks with wholesome lungs and people with COPD, and no variations between COPD sufferers who used inhaled steroids and people who didn’t.

That inhaled steroids do not seem to have an effect on fungal composition within the lungs is noteworthy, based on the researchers.
