Community bacteria

I recently posted about an amoeba that communicated via ultraviolet frequencies. Researchers have found only recently the most of bacterial life is collective, that is, 99% live in biofilms, according to Discover Magazine, July/August 2009. The strange think is that bacteria communicate by using streams of chemicals that they spew out of their cells and membranes and that they "talk" incessantly among their own species and even to unrelated bacteria living nearby. So bottom line is that (1) they live collectively, which is one thing that makes them hard to kill by antibiotics, and (2) they too, like the Paramecium that I posted about a few days ago, communicate with each other.
