The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

The directed movement of iron ions from outside of a cell into the cytoplasmic compartment. This may occur via transport across the plasma membrane or via endocytosis.

Any process involved in the controlled movement of a bacterial cell which is dependent on the presence of type IV pili. Includes social gliding motility and twitching motility.

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.

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.

The directed movement of iron ions from outside of a cell, across the cell outer membrane and into the periplasmic space.
