Bacterial surface proteins in infectious disease, commensalism and biotechnology

The focus of our research is the basic mechanisms involved when bacteria infect the human host. We study, at the molecular level, the function of bacterial surface proteins and protein appendages involved in infectious processes and bacteria-host interactions. A special emphasis is on uropathogenic bacteria, health-promoting lactic acid bacteria and bacterial antibiotic resistance. We also apply bacterial proteins and protein complexes biotechnologically for medical or diagnostic purposes.
