| 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 |
| phylogenetic and molecular characterization of h9n2 influenza isolates from chickens in northern china from 2007-2009. | the repeated transmission to pigs and humans, and the long-term endemicity in terrestrial poultry of h9n2 viruses in china lend urgency to the study of their ecology and pathogenicity. in the present paper, we reported an h9n2 virus sublineage isolated from chickens in northern china from 2007 to 2009 has high lethality for mice. phylogenetic analysis of the full genome indicated that six representative h9n2 isolates shared high homology to each other, and they clustered in the same sublineage w ... | 2010 | 20927364 |
| genetic diversity of h9n2 influenza viruses from pigs in china: a potential threat to human health? | pandemic strains of influenza a virus might arise by genetic reassortment between viruses from different hosts. pigs are susceptible to both human and avian influenza viruses and 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 summarize and report for the first time the coexistence of 10 (a-j) genotypes in pigs in china by analyzing the eight genes of 28 swi ... | 2010 | 21115230 |
