Acta vet. scand. 2005 46 193-202. -A total of 119 fresh faecal samples were collected from graylag geese migrating northwards in April. Also cloacal swabs were taken from 100 carcasses of graylag geese shot during the hunting season in August. In addition samples were taken from 200 feral pigeons and five mallards. The cultivation of bacteria detected Campylobacter jejuni jejuni in six of the pigeons and in one of the mallards. Salmonella diarizona 14 k z53 was detected in one graylag goose while all pigeons and mallards were negative for salmonellae. No avian paramyxovirus was found in any of the samples tested. One mallard from an Oslo river was influenza A virus positive confirmed by RT-PCR and by inoculation of embryonated eggs. The isolate termed A Duck Norway 1 03 was found to be of H3N8 type based on sequence analyses of the hemagglutinin and neuraminidase segments and serological tests. This is the first time an avian influenza virus has been isolated in Norway. The study demonstrates that the wild bird species examined may constitute a reservoir for important bird pathogens and zoonotic agents in Norway.
