This workshop will provide you with the current regulatory developments in relevant guideline documents e.g. Ph Eur 5.1.2. USP <1229.8> or <1035> regarding Biological Indicators (BI) and practical experiences of industrial experts and BI manufacturers on validation of processes, evaluating BI resistance and more.
Furthermore, you will get the possibility to discuss the challenges in the use of BI with speakers and colleagues during the presentation and the following panel discussion.


Manufacturers of sterile medicinal products as well as producers of medical devices should provide safe and microbiological unobjectionable products. Therefore, they have to validate their processes for sterilisation, for autoclaving and for room gassing and fogging. In addition to multidisciplinary teamwork, this also requires suitable and high-quality bioindicators. USP <1035> defines BI as a characterized preparation of a specific microorganism that provides a defined and stable resistance to a specific sterilisation process which will be used in the performance qualification of the sterilisation equipment as well as in the development and establishment of a stable , validated sterilisation processes.

Target Group

Microbiologists from pharmaceutical and biopharmaceutical
Manufacturer of medical devices
Responsible QC/QA staff
Experts from contract laboratories
Manufacturer and suppliers of BI
Responsible Authorities


USP Thinking on Bioindicators
Radhakrishna Tirumalai, USP
Biological Indicators ( BI) are only tools to measure efficacy of the sterilization process
BI is not the target of the Sterilization process. It is the bioburden in the article that is being sterilized that should be the focus for the process.
Complete destruction of a BI is not necessary to develop a validated sterilization process
