Bacteria that are resistant to antibiotics can live on the surfaces of plants or within the soil, but they can also survive in clouds, meaning they can travel thousands of kilometres and potentially invade new environments, a recent study found.

Researchers from Université Laval in Quebec and Université Clermont Auvergne in France showed, for the first time, that bacteria carrying antibiotic-resistant genes can be harboured and carried in the atmosphere.

“Considering that the atmosphere is a system that is pretty harsh for the bacteria, (the number they found) is quite a lot, actually,” said Florent Rossi, first author of the study and postdoctoral fellow at Université Laval’s Faculty of Science and Engineering.

Antimicrobial resistance genes are a naturally occurring phenomenon present everywhere in nature, he explained, adding the scientific community has known for a long time that these genes can exist in the air. However, “what we didn’t know is how high they can be and how far they can travel. And the fact that we found them in clouds highlights that they can travel for long distances,” Rossi stated.
