Measurement of systemic and local respiratory cell-mediated immunity after influenza infection in chickens.
splenic and peripheral lymphocytes. In addition, protocols to isolate lymphocytes from the respiratory tract — the trachea and the lung — have been adapted for local CMI evaluation after similar ex vivo ...
Intranasal DNA vaccination induces potent mucosal and systemic immune responses and cross-protective immunity against influenza viruses.
induced by intranasal immunization using formulated DNA. We show that formulation with the DNA carrier polyethylenimine (PEI) improved by a 1,000-fold the efficiency of gene transfer in the respiratory ...
Development of a foot-and-mouth disease infection model in severe combined immunodeficient mice for the preliminary evaluation of antiviral drugs.
virus-induced morbidity (including respiratory problems and weight loss) with subsequent mortality. Inoculations with strain A₂₂ Iraq resulted in a reproducible mean time of death of 6 dpi (this was shorter for ...
Influenza A strain-dependent pathogenesis in fatal H1N1 and H5N1 subtype infections of mice.
respiratory distress syndrome. In the absence of any virus labeling, a histologist could readily distinguish infections caused by these 2 viruses. The different histologic features described in this study here ...
Prior infection with an H1N1 swine influenza virus partially protects pigs against a low pathogenic H5N1 avian influenza virus.
peripheral blood mononuclear cells. All control pigs showed clinical signs and H5N1 virus isolation from the respiratory tract post-challenge. The H1N1-immune pigs, in contrast, showed a complete clinical ...
Comparative pathogenesis of an avian H5N2 and a swine H1N1 influenza virus in pigs.
pathogenesis of a low pathogenic (LP) H5N2 AIV with that of an H1N1 swine influenza virus. The respiratory tract and selected extra-respiratory tissues were examined for virus replication by titration, ...
Vaccination of calves using the BRSV nucleocapsid protein in a DNA prime-protein boost strategy stimulates cell-mediated immunity and protects the lungs against BRSV replication and pathology.
