genetic relatedness between a/swine/iowa/15/30(h1n1) and human influenza viruses.	the nucleotide sequences of the m and ns1 genes of influenza virus a/swine/iowa/15/30 (a/sw/iw/30)(h1n1) were determined with cloned dnas and compared with reported sequences of human and avian influenza viruses. a/sw/iw/30 virus was found to be closely similar to a/pr/8/34(h1n1) virus in the nucleotide sequences of the m and ns1 genes, the base differences between the two strains being 64 out of 1027 nucleotides in the m gene and 52 out of 740 in the ns1 gene. based on the assumptions that thes ...	1984	6495656
transmissibility of two avian influenza a viruses (h7 n6) between chickens.	differences were demonstrated in the transmissibility of two strains of avian influenza virus among chickens. one strain, a/duck/victoria/76 (h7n6) spread quickly and infected all incontact chickens, whereas a/chicken/victoria/75 (h7n6) spread slowly and failed to infect all incontact chickens. these strains were isolated in the same locality at about the same time in a region where the viruses, and the disease fowl plague, had not been previously recognised.	1981	18770163
prevalence of avian influenza viruses, borrelia garinii, mycobacterium avium, and mycobacterium avium subsp. paratuberculosis in waterfowl and terrestrial birds in slovakia, 2006.	the prevalence of borrelia, mycobacteria and avian influenza virus (aiv) infections, together with the distribution of different aiv subtypes, was studied in migratory waterfowl and terrestrial birds trapped in three localities in slovakia during 2006. samples obtained from waterfowl captured in the senianske ponds area of eastern slovakia showed the highest diversity of aiv isolates. a total of 13 different subtypes were detected in 19 samples from this location (h1n2, h2n2, h3n2, h6n6, h7n6, h ...	2008	18798030
australian surveillance for avian influenza viruses in wild birds between july 2005 and june 2007.	to identify and gain an understanding of the influenza viruses circulating in wild birds in australia.	2009	19573149
haemagglutinin and neuraminidase characterization of low pathogenic h5 and h7 avian influenza viruses isolated from northern pintails (anas acuta) in japan, with special reference to genomic and biogeographical aspects.	pintails constitute an important host of avian influenza viruses (aivs). genetic, molecular, and antigenic characteristics of h5 and h7 aivs, which we isolated from northern pintails (anas acuta) wintering in japan, were analyzed and found to be linked to various ecological features, chiefly in terms of gene geography, as shaped by various migratory aquatic host species. although all the isolates were found to be of low pathogenicity (lp), we explored gene predispositions that may potentially un ...	2010	19916042
an outbreak of h7n6 low pathogenic avian influenza in quails in japan.	in february and march 2009, a total of seven quail farms in the aichi prefecture in japan were found to be infected with an avian influenza (ai) virus. low pathogenic ai viruses, subtype h7n6, were isolated from three of these farms. the infection was eliminated through the destruction of susceptible birds on the infected premises, movement controls of quail and other poultry in areas around infected premises, accompanied by intensive clinical, serological and virological surveillance. sentinel ...	2010	20391412
molecular analysis of h7 avian influenza viruses from australia and new zealand: genetic diversity and relationships from 1976 to 2007.	full-genome sequencing of 11 australian and 1 new zealand avian influenza a virus isolate (all subtype h7) has enabled comparison of the sequences of each of the genome segments to those of other subtype h7 avian influenza a viruses. the inference of phylogenetic relationships for each segment has been used to develop a model of the natural history of these viruses in australia. phylogenetic analysis of the hemagglutinin segment indicates that the australian h7 isolates form a monophyletic clade ...	2010	20668069
genetic characterization and susceptibility on poultry and mammal of h7n6 subtype avian influenza virus isolated in japan in 2009.	from february to march 2009, six strains of h7n6 subtype avian influenza virus were isolated from quails in three farms in aichi prefecture in japan. the isolates were shown to be low pathogenic for chicken by the examination performed using the "manual of standards for diagnostic tests and vaccines" by world organisation for animal health (oie). the deduced amino acid sequence at the cleavage site was pe (i/q/l) pkrr (nucleotide sequences were cct gaa (a/c) (t/a) a cc (a/g) aaa aga aga), sugges ...	2010	21111917
avian influenza virus wild bird surveillance in the azov and black sea regions of ukraine (2010-2011).	the azov and black sea basins are part of the transcontinental wild bird migration routes from northern asia and europe to the mediterranean, africa, and southwest asia. these regions constitute an area of transit, stops during migration, and nesting for many different bird species. from september 2010 to september 2011, a wild bird surveillance study was conducted in these regions to identify avian influenza viruses. biological samples consisting of cloacal and tracheal swabs and fecal samples ...	2012	23402128
genetic characterization of influenza a (h7n6) virus isolated from a live-bird market in thailand.	a one-year influenza a virus (iav) monitoring program was conducted in a live-bird market (lbm) in thailand. using one-step real-time rt-pcr (rrt-pcr), 2.39 % of live birds were found to be iav positive. twenty viruses could be identified as iav subtype h7n6. eight iav-h7n6 viruses were subjected to whole-genome sequencing and genetic characterization. phylogenetic analysis showed that the ha gene of thai h7n6 is grouped with those of the h7 eurasian viruses. the na gene is closely related to th ...	2016	26795160
molecular characterization of a novel reassortant h7n6 subtype avian influenza virus from poultry in eastern china, in 2016.	during the surveillance for avian influenza viruses (aivs) in live poultry markets in eastern china, in 2016, a novel reassortant h7n6 aiv was isolated from a chicken. phylogenetic analysis showed that this strain received its genes from h9n2, h7n9 and h5n6 aivs infecting poultry in china. this strain showed moderate pathogenicity in mice and was able to replicate in mice without prior adaptation. considering that this novel reassorted h7n6 virus was isolated from poultry in this study, it is po ...	2017	28105530
