Thread: Arch Virol. Genetic stability and linkage analysis of the 2009 influenza A(H1N1) virus based on sequence homology.

Quote: Two North American swine strains and 2 Eurasian swine strains were identified as possible ancestors of S-OIV 2009. Based on the most recent linkage analysis with the updated influenza sequences, South Dakota avian strains were found to be the closest known relatives of S-OIV 2009. Can some explain this in layman's terms. How does an avian strain in South Dakota relate to ancestral North American and Eurasian swine strains?

Good question, especially since none in NCBI are H1N1. For all years, search for South Dakota avian HA gives: .

SG-00125 and others are triple-reassortant swine flu. Almost unchanged since 1998 (pintails,mallards got life swine vax ?, ate frozen contaminated pork ? got it from turkeys who did ? maye they make turkey-food from frozen,expired meat
