State

A biofilm is a complex, often multi-species bacterial colony that uses quorum sensing to coordinate shared behavior, such as releasing toxins together against a host.

Show

A biofilm forming inside a medical catheter can cause a life-threatening infection that resists treatments effective against free-floating bacteria.

Watch for

A biofilm's coordinated behavior comes from chemical signaling between its member cells, not from any central control structure.
