Characterization of Equine Influenza Equine A H3N 8 isolated in Egypt 2008
Abstract: Equine Influenza is one of the most economically imortant diseases of equine in countries with substantial breeding and racing industries. In Egypt, Equine influenza type 2 (H3N8) was isolated in 1989 and 2000. In July 2008, an outbreak of equine inflenza virus occured in Egypt in at least three governorates, Cairo, Alexandria and Giza. This work describes the antegnic and genetic chracteization of the virus recovered from this outbreak.
Thirty nasal swebs were collected from horses suffering from respiratory manifestation in Cairo, Alexandria and Giza governorates Virus isoation attempts were performed in SPF embryonated chicken eggs (ECE). Virus isolates were antigenically and genetically chracterized using HI,PCR and sequencing.
Influenza A virus was recovered from 25 of the30 samples collected. Fourteen were confirmed by reverse transcritase PCR and sequencing. Haemagglutinin and neuraminidase genes sequencing from selected isolates showed 98% nucleotide identity with Equine influenza A(H3N8) virus from Kanazawa, Japan and USA in 2007. In condition, Equine influenza A virus subtype H3N8 was the cause of outbreak occured in Egypt in July 2008.
