Static refers to growth inhibition. An antimicrobial described as static stops microorganisms from multiplying while the agent is present, but it does not necessarily kill them. If the agent is removed or diluted, the organisms can often resume growth. This is different from killing actions, which reduce the number of viable cells, or from sporicidal or surface-disinfection effects, which target spores or surface contaminants. Some agents may be bacteriostatic at lower concentrations and bactericidal at higher concentrations, but the term static specifically indicates preventing growth, not killing.
