In humans, higher oxygen levels during ventilation are tied to an altered bacterial composition in the lungs, and mouse experiments show a causative link.

The redondoviruses, named for their circular DNA, inhabit the human respiratory tract and may be linked to disease.

The healthy lung receives microbes from the mouth, a new model suggests.

Ancient apoptotic pathway connects humans to coral; lab-grown, light-sensing retinal tissue; tracking cancer with synthetic phospholipids; diving deep into the lung microbiome

Although it’s far less populated than the mouth community that helps feed it, researchers increasingly appreciate the role of the lung microbiome in respiratory health.

The microbiome of the lung is different in patients with the disease, which causes a thick buildup of mucus that makes breathing difficult.
