Title

ISOLATION AND IDENTIFICATION OF AVIAN INFLUENZA VIRUS H9N2 SUBTYPE

Pages

  27-38

Abstract

 In August 1998, the AVIAN INFLUENZA (AI) outbreak appeared in one of the layer farms in Tehran province. Birds on the affected farm exhibited respiratory infection and reduction of egg production with very low mortality. An agar gel precipitation (AGP) test using AN antiserum revealed the presence of the virus in the samples from the affected birds. The sera collected from the surviving birds of the affected flocks also showed the presence of antibodies against AIV by AGP test. An AVIAN INFLUENZA virus H9N2 SUBTYPE was isolated in embryonated eggs from the tracheal and clocal swabs as well as pooled visceral organs of the affected birds and coded Alchicken/Iran/259/1998/H9N2.Virulence testing of the low passage virus was undertaken at the time of the outbreak in specific pathogen free (SPF) chickens. The experimentally infected chickens showed significant clinical signs and recovered gradually without any death. The isolated virus was characterized as nHPAI on the basis of pathotyping studies in SPF chickens. It is the first report on ISOLATION of AIV from the chicken flocks in Iran.
