Bacteria Get Around

While studying bacterial colonies that thrive within very high temperatures, scientists have discovered amazing similarities among groups living far away from one another.

In particular, researchers focused upon the “molecular memories” that bacteria develop after coming into contact with viruses.  To their

astonishment, scientists found that DNA sequences were remarkably alike in tiny “critters” around the globe.

Since heat-loving bacteria are not easily transported by typical hosts such as animals or humans, theorists suspect that they get around via extensive air currents. 

As they fly the germ-laden skies, bacteria manage to exchange genetic information with cohorts the world over.  This could explain why “bacteria in isolated places share common characteristics.”  It could also produce an international resistance to antibiotics.
