Microorganisms can travel long distances in the troposphere

Analysis of air samples taken at altitudes of up to 3,000 meters above Japan has revealed the presence of a vast range of viable bacteria and fungi transported by air masses originating more than 2,000 kilometers away, in regions enriched with fertilizers and pesticides. The study reveals a new way in which human, animal and plant pathogens may travel to distant geographical regions.
