PB2 subunit of avian influenza virus subtype H9N2: a pandemic risk factor

PB2 subunit of avian influenza virus subtype H9N2: a pandemic risk factor.

Avian influenza viruses of subtype H9N2 that are found worldwide are occasionally transmitted to humans and pigs. Furthermore, by co-circulating with other influenza subtypes, they can generate new viruses with the potential to also cause zoonotic infections, as observed in 1997 with H5N1 or more recently with H7N9 and H10N8 viruses. Comparative analysis of the adaptive mutations in polymerases...

Optimizing the process of inactivating influenza virus subtype H9N2 by formalin in the production of killed avian influenza vaccine

Avian influenza is one of the most important diseases in avian industry, which also threats human population. Thus, vaccination is necessary for controlling this viral disease. In this study, killed vaccine of avian influenza subtype H9N2 and formalin solution (for virus inactivation) were used. It is necessary to study the effect of different factors such as formalin concentration, as well as ...

Detection and Isolation of H9N2 Subtype of Avian Influenza Virus in House Sparrows (Passer domesticus) of Ahvaz, Iran

Avian influenza (AI) is an acute infectious disease with worldwide significance causing extensive economic losses in the poultry industry. Avian influenza viruses (AIVs) belong to the family Orthomyxoviridae and categorized in the genus influenza virus A. These viruses have been isolated from more than 100 species of free-living birds. Migratory birds are considered as reservoirs for AIVs and a...
