Enzootic and zoonotic virus research: The Lars Erik Larsen group

The overarching goal of our work is to contribute to increased animal welfare and food safety in the Danish animal production. The core research areas are enzootic viral diseases in pigs and other production animals and zoonotic viruses in pigs and birds.
