It is the aim of this Live Online Training to familiarise responsible personnel from production, quality assurance and engineering with microbiological questions. The participants learn how to interpret microbiological data and which consequences these have for the production.


The quality of drugs and the quality assurance during production are above all determined by their microbiological characteristics. The microbiological requirements on drugs are laid down in various regulations. When an authority inspects a company, it will focus its attention on these and on the requirements made on hygiene.

In their daily work, the responsible personnel in the production units has to understand microbiological results and evaluate their significance for further decisions. However, in practice many microbiological results are misinterpreted and thus often the wrong conclusions are drawn from them. When asked for the most frequent misinterpretations of microbiological results, pharmaceutical microbiologists gave the following answers.
  • The difference between bioburden and sterility testing (are they the same?)
  • The use of disinfectants guarantees the sterility of the object, surface, culture treated.
  • The distribution of microorganisms in a sample or on a surface is uniform.
  • Motile microorganisms can swim hundreds of meters in an hour causing contamination problems in remote parts of the facility.
  • How can different media formulations give different results?
  • Microbial tests described in the Pharmacopoeias can always be validated, no matter what the matrix is, how aggressive it is, e.g. NaOH, how high the concentrations of antibiotics are etc.
  • Identification results are absolute and unequivocal, especially when computer-generated.
  • Underestimating the importance of cleaning prior to disinfection.
  • Environmental monitoring results provide an accurate risk assessment during production.
  • How can clean room surfaces not be heavily contaminated when the air counts are out of specification?
  • How can endotoxins be present when the bioburden is nil?
  • How can the titre of a virus reference standard change according to the detection cell line used?
  • WFI is sterile.
  • Filters are absolute.
  • UV light disinfects and is capable of sterilising surfaces and water.
This listing appears to cover all aspects of microbiology from the interpretation of straight forward issues concerning environmental monitoring, bioburden results and identifications – through to the more complex issues surrounding virology results for the biologics/biotech people.
The misinterpretation of microbiological results often gives rise to the following misunderstandings:
  • Huge environmental monitoring programmes (more is better).
  • Rejection of batches due to minor out-of- specification results.
  • Delayed registration objectives and to attend appeal hearings.
  • Numerous contamination incidents due to the application of inappropriate solutions to problems.
  • Senseless promises made to regulatory authorities without scientific rationale based on the concept of quality.

Target Group

This Live Online Training is designed for responsible personnel from production, quality assurance, regulatory affairs and engineering that has to make judgements, release products and take actions on the basis of the microbiological data supplied.

Technical Requirements

For our Live Online Training Courses and Webinars, we use Cisco WebEx, one of the leading suppliers of online meetings.

At http://www.webex.com/test-meeting.html you can check if your system meets the necessary requirements for the participation at a WebEx meeting and at the same time install the necessary plug-in.  Please just enter your name and email address for the test. If the installation is not possible because of your rights for the computer system, please contact your IT department. WebEx is a standard nowadays and the necessary installation is fast and easy.

Examples and Case Studies Sessions
The objective of these special sessions is to give the participants some hands on experience with the fundamentals of microbial techniques and the difficulties associated with interpretation. Real cases will show sources of contamination, ways of root cause analysis and defining corrective and preventive actions.
