Small talk: cell-to-cell communication in bacteria

Bassler BL · Cell 2002

Review

Key finding

Bacteria use secreted chemical signals to count their own numbers and coordinate group behaviour.

In plain language

The paper that framed bacterial signalling as conversation. It lays out how bacteria release small molecules, sense how much is around, and change what they do once the crowd is big enough.

How much weight this carries

Repeatedly demonstrated, with agreement across independent groups.
