The research performed at the Laboratory of Parasitology is situated at the crossroads of immunology and parasitology. The ultimate goal is to unravel the host-parasite interplay during parasitic infections of the gastrointestinal tract and provide the essential information needed for the development of immunological control strategies to combat these infections. The research includes the analysis of the host immune responses combined with detailed research into parasite biology. The parasite species that are currently the focus of our research include worms such as Ostertagia ostertagi and Cooperia oncophora infecting cattle and Ascaris suum in pigs as well as the protozoan parasite Giardia duodenalis.
