Exposure to a Low Pathogenic A/H7N2 Virus in Chickens Protects against Highly Pathogenic A/H7N1 Virus but Not against Subsequent Infection with A/H5N1
Recent evidences have demonstrated that the presence of low pathogenic avian influenza viruses (LPAIV) may play an important role in host ecology and transmission of avian influenza viruses (AIV). While some authors have clearly demonstrated that LPAIV can mutate to render highly pathogenic avian influenza viruses (HPAIV), others have shown that their presence could provide the host with enough...
متن کاملProtection and Virus Shedding of Falcons Vaccinated against Highly Pathogenic Avian Influenza A Virus (H5N1)
Because fatal infections with highly pathogenic avian influenza A (HPAI) virus subtype H5N1 have been reported in birds of prey, we sought to determine detailed information about the birds' susceptibility and protection after vaccination. Ten falcons vaccinated with an inactivated influenza virus (H5N2) vaccine seroconverted. We then challenged 5 vaccinated and 5 nonvaccinated falcons with HPAI...

Immunofluorescence Method for The Detection of Non-Pathogenic Influenza Virus
The direct F.A. Method has been used for differentiation of virulent and avirulent lines of influenza viruses. A positive fluorescence was obtained indicating the level of virus in the tissues, sorbing with dried mouse powder helped to reduce non-specific staining. The virulent line showed the greatest number of fluorescent cells with the peak at 10 hours. the non-virulent lines showed a gra...
