Bacteria often leave their hosts feeling under the weather. And even when the hosts are high-altitude parcels of air, microbes can be a source of inclement conditions, a Montana research team finds.

Both groups reported their findings May 24 at the American Society for Microbiology meeting in New Orleans.
These data add to a growing body of evidence that biological org...
