Characterization of a Chicken Embryo-Adapted H9N2 Subtype Avian Influenza Virus
The low pathogenic avian influenza (LPAI) caused by H9N2 virus has generated economic losses in the Korean poultry industry since 1999, but field isolates could not be used for killed oil emulsion vaccine directly because of low productivity in embryonated chicken eggs (ECE). Therefore, we established a vaccine strain, KBNP-0028, by passage through ECE with allantoic fluid showing the highest v...
متن کاملOptimization of incubation temperature in embryonated chicken eggs inoculated with H9N2 vaccinal subtype of avian influenza virus
There are little information about growth properties of low pathogenic (LP) avian influenza virus (AIV) in embryonated chicken eggs (ECEs) at different incubation temperatures. Knowledge of this information increases the quantity and quality of antigen in vaccine production process. For this purpose, 10-5 dilution of AIV (A/Chicken/Iran/99/H9N2) was inoculated (Intra-allantoic) into ...
متن کاملAssessing the excretion time of Iranian endemic influenza virus (H9N2 subtype) from laying chicken breeds
Background: The H9N2 subtype of the influenza virus, which is endemic in many regions of Iran, is considered as a candidate for future pandemics. In the present study, excretion time of the Iranian endemic influenza virus (H9N2 subtype) from the feces and pharyngeal secretions of laying chicken breeds was evaluated. Methods: This experimental study conducted at the Diagnostic Laboratory Scienc...
