Gunther Antonissen graduated from Ghent University, Belgium in 2011. He received a PhD in Veterinary Sciences at Ghent University in 2015, having studied the predisposing effect of the mycotoxins deoxynivalenol and fumonisins on necrotic enteritis in broiler chickens. Gunther Antonissen is appointed as chairholder of the Chair Poultry Health Sciences at Ghent University. The poultry research of the group of prof. Antonissen is multidisciplinary, focusing on a better understanding of the pathogenesis of infectious and non-infectious diseases, improving diagnostics, improving animal welfare and demonstrating the efficacy and safety of prevention and treatment strategies. Current research is related to gut health (alternatives to antibiotics, diagnostics), mycotoxins and endotoxins (e.g. impact on animal and human health, interaction of mycotoxins and infectious diseases, mechanism of action and safety of detoxifying agents), host-pathogen interaction, antimicrobial resistance, and poultry welfare (monitoring and interventions).
