| are seals frequently infected with avian influenza viruses? | influenza a virus isolates of the h4n5 subtype (which has previously been detected only in birds) were recovered from harbor seals dying of viral pneumonia on the new england coast from june 1982 through march 1983. when these isolates were compared with other mammalian and avian viruses in serological assays and rna-rna competitive hybridization, it was found that the seal viruses were most closely related antigenically and genetically to recent avian virus strains and were readily distinguisha ... | 1984 | 6471169 |
| avian influenza in wild birds, central coast of peru. | to determine genotypes of avian influenza virus circulating among wild birds in south america, we collected and tested environmental fecal samples from birds along the coast of peru, june 2006-december 2007. the 9 isolates recovered represented 4 low-pathogenicity avian influenza strains: subtypes h3n8, h4n5, h10n9, and h13n2. | 2009 | 19523296 |
| distribution patterns of influenza virus receptors and viral attachment patterns in the respiratory and intestinal tracts of seven avian species. | this study assessed the presence of sialic acid α-2,3 and α-2,6 linked glycan receptors in seven avian species. the respiratory and intestinal tracts of the chicken, common quail, red-legged partridge, turkey, golden pheasant, ostrich, and mallard were tested by means of lectin histochemistry, using the lectins maackia amurensis agglutinin ii and sambucus nigra agglutinin, which show affinity for α-2,3 and α-2,6 receptors, respectively. additionally, the pattern of virus attachment (pva) was eva ... | 2012 | 22489675 |
| influenza a and b virus attachment to respiratory tract in marine mammals. | patterns of virus attachment to the respiratory tract of 4 marine mammal species were determined for avian and human influenza viruses. attachment of avian influenza a viruses (h4n5) and (h7n7) and human influenza b viruses to trachea and bronchi of harbor seals is consistent with reported influenza outbreaks in this species. | 2012 | 22516350 |
