Major Research Interests

The Institute of Medical Microbiology is trying to understand infectious diseases by linking applied and basic sciences, e.g. aspects of epidemiology and pathogenesis. In regards to bacteriology, we are focusing on the intestinal pathogens Campylobacter jejuni and Clostridium difficile, where we use molecular approaches to identify and characterize virulence-associated factors, such as those involved in invasion (Campylobacter) or in spore regulation (Clostridium). In addition, the epidemiology of both pathogens in different regions and environments is under investigation.

Fungal infections caused by Candida and Aspergillus is a second major research topic. Like in bacterial infections, antimicrobial resistances are an emerging threat in mycology as well. Therefore, we focus on analyzing the epidemiology and the mechanisms of antifungal resistances.

The protozoan parasite Toxoplasma gondii usually causes asymptomatic infections in immunocompetent adults leading to lifelong persistence especially in the brain and in muscle tissue. Infections are especially dangerous during pregnancy and in immuno-compromised individuals (i. e. patients suffering from AIDS). We are interested in the epidemiology of toxoplasmosis as well as in the cross-talk between the parasite and its host cell on a molecular level. Here, we investigate how the parasite (i) modulates the host cell capacity for MHC-restricted antigen presentation and (ii) inhibits apoptosis of the infected cell. Both mechanisms allow intracellular persistence.

Recently, we also started to develop the theme Global Health in regards to infectious deiseases and cooperate with scientists from Ghana, Kenya, and Tanzania
In addition, we are appointed the National Reference Center for Systemic Mycoses. In this respect, we are investigating fungal factors and mechanisms that are involved in pathogenesis of mycoses; i.e. cell wall structure and differentiation processes.
