| origin of highly pathogenic h5n1 avian influenza virus in china and genetic characterization of donor and recipient viruses. | genetic analysis of all eight genes of two nanchang avian influenza viruses, a/duck/nanchang/1681/92 (h3n8-1681) and a/duck/nanchang/1904/92 (h7n1-1904), isolated from jiangxi province, china, in 1992, showed that six internal genes of h3n8-1681 virus and five internal (except ns gene) genes of h7n1-1904 virus were closely similar to a/goose/guangdong/1/96 (h5n1) virus, the first highly pathogenic avian influenza (hpai) virus of subtype h5n1 isolated in asia. the neuraminidase (na) gene of gs/gd ... | 2007 | 17947535 |
| genetic analyses of h5n1 avian influenza virus in mongolia, 2009 and its relationship with those of eastern asia. | in may and august 2009, 14 highly pathogenic h5n1 isolates were obtained from migratory birds in central mongolia. to trace the genetic lineage of the isolates, nucleotide sequences of all eight genes were determined and phylogenetically analyzed. hemagglutinin and nucleoprotein genes were clustered in clade 2.3.2. the polymerase acidic gene was related to the isolates of south korea and japan obtained in 2003 and 2004 outbreaks, and a migratory duck isolate from jiangxi, china. the neuraminidas ... | 2011 | 20580497 |
| isolation and genetic characterization of avian origin h9n2 influenza viruses from pigs in china. | as pigs are susceptible to infection with both avian and human influenza a viruses, they have been proposed to be an intermediate host for the adaptation of avian influenza viruses to humans. in april 2006, a disease caused by highly pathogenic porcine reproductive and respiratory syndrome virus (prrsv) occurred in several pig farms and subsequently overwhelmed almost half of china with more than 2,000,000 cases of pig infection. here we report a case in which four swine h9n2 influenza viruses w ... | 2008 | 18403137 |
| an epidemiological study of influenza viruses among chinese farm families with household ducks and pigs. | to examine the possibility of interspecies transmission and genetic reassortment of influenza viruses on farms in southern china, we surveyed 20 farm families living outside the city of nanchang who raised pigs and ducks in their homes. weekly interviews of family members and virus isolation studies of throat swabs and faecal samples, collected from september 1992 to september 1993, established the seasonal pattern of respiratory tract infections in these families and identified 11 influenza vir ... | 1996 | 8760967 |
| emergence and evolution of h10 subtype influenza viruses in poultry in china. | the cases of human infections with h10n8 viruses identified in late 2013 and early 2014 in jiangxi, china, have raised concerns over the origin, prevalence, and development of these viruses in this region. our long-term influenza surveillance of poultry and migratory birds in southern china in the past 12 years showed that h10 influenza viruses have been introduced from migratory to domestic ducks over several winter seasons at sentinel duck farms at poyang lake, where domestic ducks share their ... | 2015 | 25589662 |
