[h=3]Russia reports H5N1 detections in wild birds[/h] Russia detected highly pathogenic avian influenza H5N1 in seven healthy wild birds, according to an Aug 21 report posted by the World Organization for Animal Health (OIE).
The birds were hunted in three towns in Novosibirskaya Oblast, located in southwestern Siberia, as part of Russia's ongoing H5N1 monitoring activities. On Jun 9, laboratory testing confirmed H5N1 in 4 rooks, 1 mallard, 1 crane, and 1 unidentified waterfowl.
Russia last reported on Aug 11 a detection of H5N1 in a whooper swan found dead in the south-central part of the country.

[h=3]H7N9 gene study shows evolution between waves, regional influences[/h] Genetic analysis of H7N9 avian influenza viruses collected during the third wave of outbreak activity last fall from poultry environments and markets in China's Guangdong province showed that they descended from viruses that circulated during the second wave. A research team from China described their findings recently in an early online edition of Emerging Infectious Diseases.
They fully sequenced isolates collected from live poultry market and farm surveillance between Sep 1, 2014, and Feb 28, 2015. Guangdong province, located in the southern part of the country, has been one of China's hardest hit provinces during H7N9 activity. Of 14 isolates studied, 13 were from live poultry markets and 1 was from a farm.
The viruses in the third wave fell into two lineages, which were closely related to the H7N9 viruses that sickened humans in the same local or nearby regions, the team found. Researchers suggested that the dominant H7N9 strains had a dynamic process for adapting to the local environment, and they noted that the internal genes showed regional hallmarks, which might relate to the transport of live birds across provinces or the influence of migratory birds.
