Avian influenza viruses (AIVs) are maintained in wild bird reservoirs, particularly in mallard ducks and other waterfowl. Novel evolutionary lineages of AIV that arise through genetic drift or reassortment can spread with wild bird migrations to new regions, infect a wide variety of resident bird species, and spillover to domestic ...

Phylogeographic evidence for the inter- and intracontinental dissemination of avian influenza viruses via migration flyways.

Junki Mine, Yuko Uchida, Kirill Sharshov, Ivan Sobolev, Alexander Shestopalov, Takehiko Saito,

Genetically related highly pathogenic avian influenza viruses (HPAIVs) of H5N6 subtype caused outbreaks simultaneously in East Asia and Europe-geographically distinct regions-during winter 2017-2018. This situation prompted us to consider whether the application of phylogeographic analysis to a particular gene segment of AIVs could provide clues for understanding how AIV had ... Read more >>

Genetics and pathogenicity of H5N6 highly pathogenic avian influenza viruses isolated from wild birds and a chicken in Japan during winter 2017-2018.

Junki Mine, Yuko Uchida, Momoko Nakayama, Taichiro Tanikawa, Ryota Tsunekuni, Kirill Sharshov, Nobuhiro Takemae, Ivan Sobolev, Alexander Shestpalov, Takehiko Saito,

An H5N6 highly pathogenic avian influenza virus (HPAIV) outbreak occurred in poultry in Japan during January 2018, and H5N6 HPAIVs killed several wild birds in 3 prefectures during Winter 2017-2018. Time-measured phylogenetic analyses demonstrated that the Hemagglutinin (HA) and internal genes of these isolates were genetically similar to clade 2.3.4.4.B ... Read more >>

Marina Gulyaeva, Kirill Sharshov, Mizuho Suzuki, Ivan Sobolev, Yoshihiro Sakoda, Alexander Alekseev, Mariya Sivay, Lidia Shestopalova, Michael Shchelkanov, Alexander Shestopalov,

Thirty-two muskrats (Ondatra zibethicus) were captured for surveillance of avian influenza virus in wild waterfowl and mammals near Lake Chany, Western Siberia, Russia. A/muskrat/Russia/63/2014 (H2N2) was isolated from an apparently healthy muskrat using chicken embryos. Based on phylogenetic analysis, the hemagglutinin and neuraminidase genes of this isolate were classified into ... Read more >>
