  • Biological indicator system to detect effectiveness of sterilization
    Patent number: 7326562
    Abstract: A novel biological indicator system to detect the effectiveness of a sterilization treatment for assessing the viability of and/or changes in bacterial spores exposed to sterilization or disinfection by multi-angle light scattering thereby detecting a change in the spores as indicators of spore viability and the efficacy of the sterilization or disinfection.
    Type: Grant
    Filed: November 17, 2005
    Date of Patent: February 5, 2008
    Assignee: ICF Technologies, Inc.
    Inventors: Ira C. Felkner, Joseph P. Laico
  • Kits and methods for determining the effectiveness of sterilization of disinfection processes
    Patent number: 7183048
    Abstract: The invention relates to methods and kits and methods for assessing the effectiveness of a sterilization process by determining the release of dipicolinic acid (DPA) from bacterial or other spores that contain DPA. A biological indicator containing a spore may be included together with articles being sterilized, and an assay of DPA released from the spore can be performed moments after the sterilization process is completed, or during the process. The kits and methods thus provide a rapid and reliable method of assessing the effectiveness of a sterilization process and, consequently, assure the sterility of article subjected to the same process.
