Abstract: A biological sterilization indicator, system, and methods of determining the effectiveness of a sterilization process. The biological sterilization indicator can include a locus of spores, a reservoir containing a liquid, and a sterilant path positioned to provide fluid communication between ambience and the locus of spores. The reservoir can have a closed state in which the reservoir is not in fluid communication with the locus of spores and an open state in which the reservoir is in fluid communication with the locus of spores. The biological sterilization indicator system can include the biological sterilization indicator and a detection device adapted to be coupled to the biological sterilization indicator. In some embodiments, the method can include assaying the spores for a detectable change in a characteristic, and detecting substantially all of the detectable change.

Abstract: A biological sterilization indicator (BI) system and method. The system can include a BI and a reading apparatus comprising a well. The BI can include a housing, which can include a first portion, and a second portion movable between a first “unactivated” position and a second “activated” position. The BI can further include a frangible container containing a liquid and dimensioned to be positioned in the housing. The reading apparatus can be configured to detect activation of the biological sterilization indicator, for example, by detecting that the second portion is in the second position, and/or by detecting that the liquid from the frangible container is present in a specific chamber of the biological sterilization indicator. The method can include positioning the BI in the well of the reading apparatus and detecting activation, for example, by detecting one or more of the above conditions.
