Avian Influenza (H9N2) Outbreak In Iraq

Isolation of H9N2 Subtype of Avian Influenza Viruses during an Outbreak in Chickens in Iran

Avian influenza is an important disease of poultry with the potential to cause major epidemics resulting in significant economic losses. The presence of avian influenza viruses (AIV) in chickens in Iran has not been previously reported. An avian influenza outbreak in broiler, layer and breeder farms occurred during a very hot summer in July 1998. Three AIV isolates designated as 101, 102 and 10...

The efficacy of inactivated oil-emulsion H9N2 avian influenza vaccine

An experimental inactivated oil-emulsion H9N2 avian influenza vaccine was formulated with 3 parts ofinactivated avian influenza antigen A/Chicken/Iran/101/1998(H9N2) emulsified in 7 parts of oil adjuvant.Twelve week-old specific pathogen-free (SPF) chickens were divided into seven groups of 10 birds. Sixgroups were vaccinated with 1, 1/10th, 1/50th, 1/100th, 1/200th and 1/400th field dose of th...

Immunity Against Avian Influenza Viruspanax Ginseng Polysaccharide (GPS) Can Improve Immunity Against H9N2 Avian Influenza Virus in Chickens

The humoral immunization potential of panax ginseng polysaccharide (GPS) against H9N2 avian influenza virus (H9N2 AIV) in chickens was investigated. The effects of GPS treatment before and during H9N2 AIV infection were determined in chicken embryo fibroblast (CEF) by MTT (3(4, 5-dimethylthiazol-2-yl)-2, 3-diphenyl tetrazolium bromide) assays and quantitative RT-PCR analysis of MHC and cytokine...
