  • BIOLOGICAL INDICATORS, AND SYSTEMS AND METHODS FOR DETERMINING EFFICACY OF STERILIZATION
    Publication number: 20230235377
    Abstract: A biological indicator includes: a BI housing; a germinant container inside the BI housing and housing a germinant composition; a germinant releaser configured to release the germinant composition from the germinant container; a germinant releaser support supporting the germinant releaser and configured to bring the germinant releaser into contact with the germinant container upon application of a force to the germinant releaser support or the germinant container; a first spore carrier inside the BI housing, the first spore carrier having a plurality of spores deposited at a first surface thereof; and an imaging window at a first surface of the BI housing. A BI reader is configured to detect and quantify the presence of live spores in the BI, and includes an excitation source, a camera for capturing images of the spores over time, and a processor for analyzing the images to determine the presence of live spores.
    Type: Application
