How humans started a bacterial pandemic in chickens
Bethan Lowder from the University of Edinburgh has shown that all of the bacteria [a strain of Staphylococcus aureus] behind BCO [bacterial chrondronecrosis with osteomyelitis] share a common ancestor, which jumped from humans to chickens in Poland, around 38 years ago. From that point on, the bacterium's travel itinerary was set. Just as air travel has facilitated the spread of swine flu among humans, a global distribution network for chickens made it easy for S.aureus to spread all over the world aboard its new feathery hosts.
