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.
A Virus, H5N1 Subtype Neuraminidase Orthomyxoviridae Infections Swine Abstract: Most humans lack virus neutralizing (VN) and haemagglutination inhibition (HI) antibodies to H5N1 avian influenza viruses (AIV ...
Comparative pathogenesis of an avian H5N2 and a swine H1N1 influenza virus in pigs.
immunofluorescence and RT- PCR throughout the course of infection. Both viruses caused a productive infection of the entire respiratory tract and epithelial cells in the lungs were the major target. Compared to the ...
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.

Evaluation of virulence of Mycoplasma hyopneumoniae field isolates.
a virulent reference strain or sterile culture medium. Animals were examined daily for the presence of disease signs and a respiratory disease score (RDS) was assessed per pig. Twenty-eight days post ...
