RUSSIA - Routine avian influenza monitoring uncovered a whooper swan with the disease at a nature park by the Ingren Lake.

snip

The comparative analysis of the obtained nucleotide sequence of the H gene fragment showed that the tested isolate belonged to an Asian lineage of highly pathogenic avian influenza virus and was most similar to type A H5N1 HPAIV isolates recovered in the Tyva Republic in May, in the Astrakhan Oblast in April, 2015 and in Vietnam and China over the period from 2012 to 2014.

[TD]As part of AI monitoring, samples from a whooper swan at Ingren Lake in the Chitinsky Raion of the Zabaykalsky Krai on May 10, 2015 were analysed. Real-time RT-PCR showed H5N1 avian influenza A virus genome to be present in a sample of internal organs. The haemmaglutinin cleavage site of this virus includes several basic amino acids and has ? SPQRERRRKR ? structure which allows this virus to be characterized as highly virulent. The comparative analysis of the obtained nucleotide sequence of the H gene fragment showed that the tested isolate belonged to an Asian lineage of highly pathogenic avian influenza (lineage A/Guandong/1/96 lineage, clade 2.3.2.1) and was most similar to type A H5N1 HPAIV isolates recovered in the Tyva Republic in May, 2015 (98,83-100% identity), in the Altay Krai in 2014 (98.83% identity), in the Astrakhan Oblast in April, 2015 (98,44% identity) and in Vietnam and China over the period from 2012 to 2014 (98.44-98.04% identity).[/TD]
