The Unit of Parasite Diagnostics studies human and animal African trypanosomiases, visceral leishmaniasis and Chagas’ disease. All these diseases are caused by infections with single-cell (unicellular) Trypanosomatidae parasites.

We focus on parasitological, serological, biochemical and genetic markers for diagnosis-, and determination of the disease stage, including treatment failure and healthy carier status. We are dedicated to the development of simple, quick and reliable tests that can also be used outside the laboratory.

Our methods include the genetic modification of suitable hosts to express candidate antigens for serodiagnosis. Furthermore, we genetically modify trypanosomes with bioluminescent and fluorescent reporter genes for easy in vivo tracking of the parasites in animal models in studies on pathogenicity and treatment efficacy. 

We work together with partner institutions in many developing countries, as well as with private companies and organizations. We are a Collaborating Centre for Research and Training on Human African Trypanosomiasis Diagnostics of the World Health Organization and a Reference Laboratory for Surra of the World Animal Health Organization.

The unit is led by Prof Philippe Büscher.
