During an active wild bird survey conducted in Belgium from 2007 to 2011, two low pathogenic avian influenza (LPAI) H7 viruses were isolated from wild birds: an H7N1 virus from a common shelduck (Tadorna tadorna) and an H7N7 virus from a Canada goose (Branta canadensis). The H7 sequence analyses and intravenous pathogenicity indices indicated that they were both low pathogenic isolates and genetically related to other recent European H7 LPAIs isolated from wild birds. Interestingly, the two isolates showed different replication profiles in specific-pathogen-free (SPF) chickens, but poultry …
