| pathogenesis and transmissibility of highly (h7n1) and low (h7n9) pathogenic avian influenza virus infection in red-legged partridge (alectoris rufa). | abstract: an experimental infection with highly pathogenic avian influenza virus (hpaiv) and low pathogenic avian influenza virus (lpaiv) was carried out in red-legged partridges (alectoris rufa) in order to study clinical signs, gross and microscopic lesions, and viral distribution in tissues and viral shedding. birds were infected with a hpaiv subtype h7n1 (a/chicken/italy/5093/1999) and a lpaiv subtype h7n9 (a/anas crecca/spain/1460/2008). uninoculated birds were included as contacts in both ... | 2011 | 21314907 |
