| occurrence of hsw 1 n 1 subtype influenza a viruses in wild ducks in europe. | two identical strains of influenza a viruses antigenically related to swine influenza (hsw 1 n 1) have been isolated from adult mallard ducks (anas platyrhynchos) in southern germany. they were designated a/duck/bavaria/1/77 and a/duck/bavaria/2/77. serologic tests revealed a close antigenic relationship to the strain a/duck/alberta/35/76. experimental infections of piglets with strain a/duck/bavaria/1/77 demonstrated the susceptibility of swine to this virus strain. the virus was isolated from ... | 1980 | 6243921 |
| phylogenetic analyses of highly pathogenic avian influenza virus isolates from germany in 2006 and 2007 suggest at least three separate introductions of h5n1 virus. | in spring 2006, highly pathogenic avian influenza virus (hpaiv) of subtype h5n1 was detected in germany in 343 dead wild birds, as well as in a black swan (cygnus atratus) kept in a zoo, three stray cats, one stone marten (martes foina), and in a single turkey farm. in 2007 (june-july) the virus reoccurred in 96 wild birds at six geographically separate locations in the southeast of germany. in addition, a backyard mixed duck and goose holding was affected. real-time rt-pcr [hoffmann, b., harder ... | 2008 | 18031958 |
| [surveillance of wild birds for avian influenza a virus (aiv) in bavaria in the years 2007 and 2008]. | a monitoring programme has been initiated in bavaria to continuously control wild birds for the presence of avian influenza a virus (aiv) and to monitor the possible occurrence and accumulation of notifiable aiv subtypes as an early-warning system. in addition information about the regional, seasonal and species-specific distribution of aiv could be obtained. between july 2007 and december 2008 samples from 5864 wild birds of twelve different zoological orders had been collected (cloacal- and tr ... | 2009 | 19999383 |
