Whether the 2009 pandemic H1N1 influenza vaccine can induce heterosubtypic cross-protective anti-hemagglutinin (HA) neutralizing antibodies is an important issue. We obtained a panel of fully human monoclonal antibodies from the memory B cells of a 2009 pandemic H1N1 influenza vaccine recipient. Most of the monoclonal antibodies targeted the HA protein but(More)
BACKGROUND The 2009 swine-origin influenza virus (S-OIV) H1N1 pandemic has caused more than 18,000 deaths worldwide. Vaccines against the 2009 A/H1N1 influenza virus are useful for preventing infection and controlling the pandemic. The kinetics of the immune response following vaccination with the 2009 A/H1N1 influenza vaccine need further investigation. (More)
Fifteen virulent Newcastle disease viruses (NDVs) were isolated from diseased birds in Eastern China in 2005. To investigate the antigenic variation in the epitopes on NDV hemagglutinin-neuraminidase (HN) protein, these isolates, together with six reference strains, were subjected to the hemagglutination inhibition (HI) tests using five HI-positive(More)
New-emerging variants of Pseudorabies virus (PRV) compromise the protection provided by current vaccines and cause the death of all ages of vaccinated pigs since 2011. New vaccines based on current circulating PRV strain are needed to control the spread of disease since the variants are antigenically different from classical strains of virus. In this study,(More)
The new-emerging PRV variants plague the vaccinated pigs and caused huge economic loss to local pig industry in China since 2011. The current commercial PRV vaccines cannot provide complete protection as the new-emerging PRV variants are antigenically different from the classical viruses. It is urgent to develop more safe and effective PRV vaccines based on(More)
The truncated spike protein (S1, 390-789aa) of porcine epidemic diarrhea virus was expressed as a recombinant protein in Baculorvirus expression system. Female BALB/c mice were immunized with the purified recombinant S1 (rS1) protein and two monoclonal antibodies, designated 8A3A10 and 12C4G12, were generated by hybridoma technique. The two monoclonal(More)
