A process in which planktonically growing microorganisms of the same species grow at a liquid-air interface or on a solid substrate under the flow of a liquid and produce extracellular polymers that facilitate matrix formation, resulting in a change in the organisms' growth rate and gene transcription.

A process in which microorganisms of the same species attach to and grow on an inanimate surface such as a rock or pipe, and produce extracellular polymers that facilitate attachment and matrix formation, resulting in an alteration in the phenotype of the organisms with respect to growth rate and gene transcription.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.

Bacterial-type flagellum-dependent cell motility in which the action of numerous flagella results in the smooth movement of a group of cells along a solid surface. Swarming motility is observed in groups of bacteria.
