| [seroepidemiologic survey for a/pr/8/34 (h1n1) virus from chinese residents]. | a total of 414 serum specimens were collected from the residents with ages of < or = 20 year old in eight different parts of china for detecting antibody to a/pr/8/34(h1n1) influenza virus with hi test. of them, 24 had antibody with hi titers > or = 20 to a/pr/8/34(h1n1) virus. these 24 specimens were tested with the same method using a/swine/iowa/15/30 (h1n1), a/guangxi/10/94(h1n1) and a/beijing/53/97(h1n1) viruses. the results showed that except 5 of them had antibody with hi titers 20-40 to a ... | 1998 | 12526320 |
| [phylogenetic analysis of human/swine/avian gene reassortant h1n2 influenza a virus isolated from a pig in china]. | our aim in this study was to determine the genetic characterization and probable origin of the h1n2 swine influenza virus (a/swine/guangxi/13/2006) (sw/gx/13/06) from lung tissue of a pig in guangxi province, china. | 2008 | 18590231 |
| isolation and genetic characterization of avian-like h1n1 and novel ressortant h1n2 influenza viruses from pigs in china. | as pigs are susceptible to both human and avian influenza viruses, they have been proposed to be intermediate hosts or mixing vessels for the generation of pandemic influenza viruses through reassortment or adaptation to the mammalian host. in this study, we reported avian-like h1n1 and novel ressortant h1n2 influenza viruses from pigs in china. homology and phylogenetic analyses showed that the h1n1 virus (a/swine/zhejiang/1/07) was closely to avian-like h1n1 viruses and seemed to be derived fr ... | 2009 | 19460353 |
