A Virus Can Eavesdrop On Bacterial Communication

A researcher had an idea about viruses that was wild. And it turned out to be true.
In these images, <em>E coli</em> bacteria harbor proteins from a bacteria-killing virus that can eavesdrop on bacterial communication. At left, one protein from the virus has been tagged with a red marker. At right, the virus has overheard bacterial communication indicating the bacteria have achieved a quorum; it sends its protein to the poles of the cell (yellow dots).

Like many a cockamamie idea, this one was so crazy, it just might work.

But then again, the Bassler Microbiology Lab at Princeton University was built on crazy ideas that proved right, like that bacteria talk to each other, says Bonnie Bassler, director of the lab, chair of the Department of Molecular Biology at Princeton and investigator at the Howard Hughes Medical Institute.

Of course, they don't speak in so many words. Rather, they communicate with chemical signals, she says – a discovery that helped earn her a in 2002.
