Sero-Epidemiology of Avian Influenza Virus in Native Chicken in Bangladesh

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...

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

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 ...

Experimental Study on the Pathogenicity of Avian Influenza A/Ch/It/5093/99(H7N1) Virus in Chicken

In this study, the pathogenicity of A/Ch/It/5093/1999 H7N1 which had been isolated from chicken during the outbreak in Italy was assessed in chicken by experimental infection virus. Ten SPF chickens of four week-old were inoculated with this virus, and five chickens were inoculated with uninfected allantoic fluid. For determination of virus shedding, oropharyngeal and cloacal swabs were taken f...
