摘要： A self-contained biological indicator is provided. The biological indicator includes a housing having at least one liquid-impermeable wall that forms an opening into a compartment. Disposed in the housing are a plurality of test microorganisms; an aqueous liquid medium disposed in an openable container; and a pH indicator dye substrate having a pH indicator dye bound thereto. The pH indicator is not disposed in or in liquid contact with the aqueous liquid medium. The biological indicator further comprises a nutrient composition that facilitates germination and/or outgrowth of the test microorganism, if viable; The nutrient composition can be disposed in the housing or is disposed in the openable container that is in selective fluid communication with the compartment.
