Phylogenetic Analysis of Low-Pathogenicity Avian Influenza H6N2 Viruses from Chicken Outbreaks (2001–2005) Suggest That They Are Reassortants of Historic Ostrich Low-Pathogenicity Avian Influenza H9N2 and H6N8 Viruses

Abstract excerpt

Low-pathogenicity (LPAI) and high-pathogenicity (HPAI) avian influenza viruses are periodically isolated from South African ostriches, but during 2002 the first recorded outbreak of LPAI (H6N2) in South African chickens occurred on commercial farms in the Camperdown area of KwaZulu/Natal (KZN) Province. Sequence analysis of all eight genes were performed and phylogenetic analysis was done based on the...
