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 ...
متن کاملDetection 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...
متن کاملSequence Analysis and Phylogenetic Study of Hemagglutinin Gene of H9N2 Subtype of Avian Influenza Virus Isolated during 1998-2002 in Iran
Sequence analysis and phylogenetic study of hemagglutinin (HA) gene of H9N2 subtype of avian influenza virus isolates (outbreaks of 1998-2002) in Tehran province (Iran) were studied. Two sets of forward and reverse primers in highly conserved regions, based on sequences of HA gene in Genbank, were designed. PCR products of a 430-bp fragment of 16 isolates were sequenced and then were aligned wi...
