Histopathological Study of Intratracheally Inoculated A/Chicken/Iran/259/1998 (H9N2) Influenza Virus in Chicken

histopathological study of intratracheally inoculated a/chicken/iran/259/1998 (h9n2) influenza virus in chicken

Monitoring virus harvesting time in embryonated chicken eggs inoculated with avian influenza H9N2 vaccine strain

Knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. The present study aimed to evaluate the best harvesting time of H9N2 avian influenza virus (AIV) vaccine strain inoculated in specific pathogen free (SPF) embryonated chicken eggs (ECE)s. For this purpose, 10-5 dilution of AIV (A/Chicken/Iran/99/H9N2) was inoculated into 336, 11-day old ECE...

Histopathological Study of A/chicken/iran/772/99 (h9n2) Influenza Virus in Commercial Broiler Chickens

Avian influenza outbreaks in 1998 due to H9N2 subtype of avian influenza virus (AIV) that occurred in poultry industry in Iran caused serious economic losses. The aim of this study was to investigate the pathogenesis, clinical signs, gross and histopathological findings of the chickens experimentally inoculated with A/Chicken/Iran/772/99(H9N2) influenza virus, isolated from the commercial broil...

Optimization 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 ...

A Study on Histopathologic Changes in Chicken Following Intravenous Inoculation with Avian Influenza Virus A/Chicken/Iran/259/1998(H9N2)
