From the episode: To detect diseases earlier, let's speak bacteria's secret language | Fatima AlZahra'a Alatraktchi

Answer

In order to coordinate and organize, bacterias communicate by using signaling molecules. When bacterias are few, the molecules fall away; but when there are many, the signaling molecules accumulate, and the bacterias are able to sense and keep track of how many they are. When there are many enough, they talk and initiate a new action.
