Do bacteria "talk" to each other?

This was on Nova last night and was so interesting--both from a scientific viewpoint and from a layman's perspective. Her work is so important--we could stop the spread of bacteria-causing disease by interupting their (bacteria"s) "conversations" and therefore causing them to "lose sight of each other" and not unite.

<b> Azithromycin disrupts the information flow between PA bacteria </b>

"The drug, azithromycin (AZM), has been found to curb pathogenic bacteria. AZM combats bacteria in the PA family. Scientists have discovered that AZM prevents these bacteria from becoming aggressive and destructive. AZM blocks the machanism used by the bacteria to "measure" how many of them there are in a particular environment.

"Unaware of their numbers and how strong they've already become, the pathogens, as a result, delay their big attack. AZM, which belongs to the macrolide group of drugs, is incapable of killing PA but helps to keep the pathogen relatively benign, preventing it from moving into a more antagonistic phase wher eit would begin attacking and destroying large sections of lung tissue."
