Expand all Close all

The unit develops diagnostic assays and prevention strategies for infectious diseases, in human and veterinary medicine. A strong focus is on zoonoses and (re-)emerging viral infections. All state-of-the-art methods in virology, microbiology, molecular biology and immunology are well established, and the unit includes a BSL-3 laboratory with animal facility. Pathogens worked on in the lab include, among others, flaviviruses (West Nile virus, dengue virus, Zika virus), Influenza, PRRSV, and spore-forming bacteria. In addition, methods for the control of ectoparasites are being developed.

In order to inactivate pathogens for vaccines or other applications, we are developing a novel irradiation technology, together with three other Fraunhofer Institutes. Project partners include pharmaceutical and diagnostic companies as well as funding organizations such as the Bill and Melinda Gates Foundation.

Logo EU and Logo WINGS

From 2011–2014 the unit was coordinating the EU (FP7) research consortium "WINGS: West Nile Integrated Shield Project: Epidemiology, Diagnosis and Prevention of West Nile Virus in Europe".

Diagnostic assays

The unit has know-how and technologies for the design and production of recombinant antigens from all kinds of viruses and microbes. Technologies include proprietary ways for the elimination of cross-reacting epitopes (e.g. in flavivirus diagnostic). These proteins are used for the development of serologic tests, e.g. ELISAs. Other diagnostics are PCRs (e.g. real time PCR) and virus culture.

Pathogen inactivation

The unit coordinates a consortium consisting of Fraunhofer IZI and three other Fraunhofer Institutes (FEP, IPA and IGB) for the development of low-energy electron irradiation (LEEI) for the generation of inactivated vaccines or novel diagnostic antigens.

DNA-vaccines

A platform for the development and optimization of DNA vaccines was generated. These vaccines are applied using modern technologies, such as in vivo electroporation or nanoparticles.

Recombinant vaccines

Protein-vaccines are used alone or in combination with DNA immunization (heterologous prime-boost strategies).
