Bacterial quorum sensing
Bacterial quorum sensing is a communication process where bacteria detect their population density through chemical signals. As bacteria grow, they release and sense these signaling molecules; when enough bacteria are present, the concentration of signals reaches a threshold. This triggers coordinated actions, such as forming biofilms, releasing toxins, or adjusting their behavior for survival. Quorum sensing helps bacteria act collectively, optimizing their chances of success in environments like infections or nutrient-rich areas. Essentially, it's bacteria "talking" and deciding together when to activate certain functions based on their numbers.
