This animation illustrates how bacteria form a biofilm. A biofilm - more commonly know as "slime" - is a surface-attached community of microorganisms. Formation of a biofilm involves a series of bacterial processes, including bacterial signalling and quorum sensing, production of pili and secretion of an extracellular polymer matrix.
