In this paper, to determine the pathogenicity and antigen distribution of China early H5N1 highly pathogenic avian influenza virus (HPAIV) A/GS/LN/45/04, the Sheldrake ducks were inoculated via the nostrils. Infected ducks appeared depression, orticollis and nystagmus clinical signs, hematoxylin and eosin (HE) stain found multiple organs showed different degrees of pathological changes. In addition, by Immuno-histochemistry (IHC) stain found that A/GS/LN/45/04 virus could duplicated in multiple organs, especially in brain and pancreas. These results could provide some important theoretical basis for the further study of Chinese AIVs.
Keywords: highly pathogenic avian influenza; pathology; H5N1; Sheldrake ducks
