The Protozoology Research Group is comprised of four research units performing basic and translational research on three major vector-borne protozoan parasites responsible for devastating diseases in humans and animals across the developing world: Leishmania (human leishmaniasis), Plasmodium (human malaria), Trypanosoma (human and animal African trypanosomiasis). Intensive control and elimination efforts are currently ongoing to eliminate visceral leishmaniasis in the Indian subcontinent, malaria in the three continents and HAT in Africa. Our research is closely connected to this as the acquired new knowledge and its translation into innovative tools for diagnosis and surveillance will enhance the ongoing disease-control/elimination programmes and their follow-up.
