Unit Diagnostics, Pathogen Characterisation, Parasites in Food

One of the central tasks of this unit is the assessment of risks resulting from so-called zoonotic pathogens that are of relevance to human health. Of particular interest in this regard are bacterial and parasitic pathogens that may be transmitted to humans via plant and animal foods. Moreover, the unit conducts research on pathogen-host interactions under experimental conditions and investigates specific questions relating to pathogen interaction, pathogen diagnostics and pathogen epidemiology. Our work also includes the assessment of risks from genetically modified organisms. Genetic modifications may lead, for example, to modification of virulence and pathogenicity factors of a specific agent which in turn can result in a higher risk group classification of the modified version. Genetic modifications may also occur naturally (changes in pathogens) which may also result in the emergence of novel sometimes more pathogenic agents that require adapted risk assessments leading to higher risk estimations eventually.

Another key area is the characterisation and fine differentiation of zoonotic pathogens with the aim of examining potential sources of infection for humans. Bacteriological, parasitological, serological and molecular biology detection methods are applied for this purpose. Laboratory tests are carried out under accredited conditions in accordance with generally recognised quality standards (ISO 17025).

Alongside the tasks outlined above, the unit now also extends its activities to support and advise public authorities and federal organizations with responsibilities in public safety and security, on the potential for misuse of biological pathogens and response to biological hazards.
