“…In addition, the original virus sample for 81081 was collected on 22 May 2008, while the AK08 sample was collected on 1 September of that same year. Thus, these two viruses provide another example of H9N2 AIVs demonstrating genomic constellation integrity over large geographic distances and time, similar to the results of Lee et al (6) and Ramey et al (7). Last, multiple segment sequences of AK08 were closely related genetically and temporally to sequences of AIVs collected in both Asia and North America (3).…”

“…H9 AIV, NDV and TMUV infections are three main diseases that cause considerable economic loss to the goose breeding industry (Han et al., ; Lee et al., ; Sun et al., ; Wang et al., ). The clinical symptoms and pathological changes are usually similar among them.…”

“…In addition, the goose meat industry is a significant part of the national agriculture (Li et al., ). Nonetheless, with the development of industrial scale and an increasing stocking density, infectious diseases of geese, especially AIV, NDV, TMUV, GoCV and GPV, have gradually become more endemic (Lee et al., ; Liu, Zhang, Chen, Wang, & Cheng, ; Sun et al., ; Wang et al., ; Yu, Zhu, Zheng, He, & Liu, ). These diseases can cause death or severe losses of production performance of geese, whether as a mono‐infection or co‐infection, and have always been damaging to the status of the goose breeding industry and have caused enormous economic losses (Shehata et al., ).…”

To deepen the knowledge about epidemic prevalence in the goose breeding field, a triplex PCR assay was established, and 478 samples were collected from scaled goose farms in 11 provinces in China. The results of this epidemiological investigation showed that incidence rates of H9 avian influenza and goose circovirus were the highest among five infectious diseases that were evaluated. In addition, the triplex PCR assay established remarkable sensitivity, rapidity and versatility compared to other diagnostic methods. Dual infection comprised a large proportion of the co-infections in the field, of which the combinations of H9/Tembusu, H9/goose circovirus and goose circovirus/Tembusu co-infected cases were more common. Epidemics were more severe in winter and spring. Additionally, significant differences in the prevalence of these infectious diseases were observed in association with different age groups. In addition, phylogenetic analysis, determined by the neighbour-joining method, was carried out to investigate the evolution of these viruses during the study period. For the most part, virus strains isolated during the study were consistent with most goose-origin strains isolated from the Chinese mainland over the past few years. However, mutations were observed between isolated H9 avian influenza virus strains and sequences available from GenBank, which should draw much attention.

“…Countries located along this flyway share the AIV gene pool [19]. These findings provide strong evidence suggesting not only that direct transmission of viruses occurs between Korea and China via wild birds but also that North American–Eurasian reassortant viruses are presently circulating in wild birds [20], which further indicates that wild birds, particularly migratory birds, play important roles in the reassortment of viruses between two relatively separate and dominant lineages. The seven H1Nx viruses in the present study were novel reassortments carrying genes from H1N1, H6N2, and H9N2 viruses that had been detected previously in ducks and wild birds throughout the world, suggesting that multiple subtypes of the influenza virus may co-circulate in poultry, waterfowl, and migratory birds.…”

BackgroundAs the natural hosts of avian influenza viruses (AIVs), aquatic and migratory birds provide a gene pool for genetic transfer among species and across species, forming transient “genome constellations.” This work describes the phylogenetic dynamics of H1NX based on the complete molecular characterization of eight genes of viruses that were collected from 2014 to 2015 in Anhui Province, China.MethodsHemagglutination and hemagglutination inhibition tests were used to determine the hemagglutination (HA) activity of the HA subtypes. The entire genomes of the viruses were sequenced on an ABI PRISM 3500xl DNA Analyzer. The sequences were genetically analysed to study their genetic evolution using DNASTAR and MEGA 6. The pathogenic effects of the viruses were evaluated using mouse infection models.ResultsSeven strains of the H1 subtype avian influenza virus were isolated. Phylogenetic analysis indicated natural recombination of the H1 influenza viruses between the Eurasian lineage and the North American lineage. Some genes had high sequence identity with A/bean goose/Korea/220/2011(H9N2), which is a typical case involving viral reassortment between the Eurasian lineage and the North American lineage. The results of infection experiments in mice showed that the viruses could acquire the ability to multiply in mouse respiratory organs without adaptation.ConclusionsThese findings suggest that continued surveillance of wild birds, particularly migratory birds, is important to provide early warning of possible H1 influenza epidemics and to understand the ecology of the virus.Electronic supplementary materialThe online version of this article (doi:10.1186/s40249-017-0304-4) contains supplementary material, which is available to authorized users.
