Germ Warfare ...

... just took on a new meaning.
Scientists noticed that two neighboring colonies of P. dendritiformis never grew to touch each other on an agar plate.
Interesting, but what happened next ...
The research team, led by Avraham Be’er at the University of Texas at Austin, next wanted to know whether the bacteria were just inhibiting the growth of their sibling colony or were actually killing the other colony. Upon closer examination, the team found that dead bacteria littered the fringes of both warring bacterial colonies, showing researchers the smoking gun.
Cool! Look for the article in the Dec 29 issue of PNAS (article not currently available at the time of this blog post).
