Description:
Since its identification in April 2009, an A(H1N1) virus containing a unique combination of gene segments from both North American and Eurasian swine lineages has continued to circulate in humans. The lack of similarity between the 2009 A(H1N1) virus and its nearest relatives indicates that its gene segments have been circulating undetected for an extended period. Its low genetic diversity suggests that the introduction into humans was a single event or multiple events of similar viruses. Molecular markers predictive of adaptation to humans are not currently present in 2009 A(H1N1) viruses, suggesting that previously unrecognized molecular determinants could be responsible for the transmission among humans. Antigenically the viruses are homogeneous and similar to North American swine A(H1N1) viruses but distinct from seasonal human A(H1N1).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3250984/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3250984/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garten, Rebecca J -- Davis, C Todd -- Russell, Colin A -- Shu, Bo -- Lindstrom, Stephen -- Balish, Amanda -- Sessions, Wendy M -- Xu, Xiyan -- Skepner, Eugene -- Deyde, Varough -- Okomo-Adhiambo, Margaret -- Gubareva, Larisa -- Barnes, John -- Smith, Catherine B -- Emery, Shannon L -- Hillman, Michael J -- Rivailler, Pierre -- Smagala, James -- de Graaf, Miranda -- Burke, David F -- Fouchier, Ron A M -- Pappas, Claudia -- Alpuche-Aranda, Celia M -- Lopez-Gatell, Hugo -- Olivera, Hiram -- Lopez, Irma -- Myers, Christopher A -- Faix, Dennis -- Blair, Patrick J -- Yu, Cindy -- Keene, Kimberly M -- Dotson, P David Jr -- Boxrud, David -- Sambol, Anthony R -- Abid, Syed H -- St George, Kirsten -- Bannerman, Tammy -- Moore, Amanda L -- Stringer, David J -- Blevins, Patricia -- Demmler-Harrison, Gail J -- Ginsberg, Michele -- Kriner, Paula -- Waterman, Steve -- Smole, Sandra -- Guevara, Hugo F -- Belongia, Edward A -- Clark, Patricia A -- Beatrice, Sara T -- Donis, Ruben -- Katz, Jacqueline -- Finelli, Lyn -- Bridges, Carolyn B -- Shaw, Michael -- Jernigan, Daniel B -- Uyeki, Timothy M -- Smith, Derek J -- Klimov, Alexander I -- Cox, Nancy J -- DP1 OD000490-01/OD/NIH HHS/ -- DP1-OD000490-01/OD/NIH HHS/ -- HHSN266200700010C/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):197-201. doi: 10.1126/science.1176225.
