'This is the first study to show that clouds harbor antibiotic-resistance genes of bacterial origin in concentrations comparable to other natural environments.'
The weather is cloudy, with a chance of antibiotic-resistance genes.In what can be called an intriguing revelation, a Canadian-French research team has discovered that our fluffy clouds are a "large-scale dissemination route" for bacteria carrying antibiotic-resistance genes.
"These bacteria usually live on the surface of vegetation or soil. They are aerosolized by the wind or by human activities, and some of them rise into the atmosphere and participate in the formation of clouds," explained Rossi.The scientists were able to measure the concentration of 29 subtypes of antibiotic-resistance genes carried in atmospheric air masses. On average, the clouds contained 20,800 copies of antibiotic-resistance genes per milliliter of cloud water.
