Daisy Vanrompay graduated in 1990 as doctor in Veterinary Medicine at Ghent University. She became appointed as professor (UGent) in Immunology and Animal Biotechnology in 2000. D. Vanrompay is Director of the Laboratory of Immunology and Animal Biotechnology at Ghent University and Director of the National Diagnostic Reference Laboratory for C. psittaci infections in humans. She is a member of PROVAXS, the UGhent Center for Strategic Prophylaxis and Vaccine Development and of BLUEGENT, a business development center covering the field of Aquaculture and Blue Life Sciences. She is also a member of the UGent ‘One Health’ research consortium. Here research involves: i) the development of new molecular diagnostic methods for identifying bacterial pathogens in both humans and animals, ii) unravelling the cellular and molecular pathogenesis of bacterial infections, and iii) gaining insight in the induction of protective mucosal immunity. The laboratory focuses on Chlamydia infections in humans and animals, Escherichia coli infections in ruminants and chickens and Vibrio spp, Aeromonas spp., Providencia spp. and other bacterial infections in aquatic animals (fish and shrimp). In vitro and in vivo models are used to study bacterium host interactions for developing innovative diagnostics as well as prophylactic tools such as virulence blockers, novel antimicrobials, probiotics and innovative vaccines.
