 ISOLATION OF HIGHLY PATHOGENIC AVIAN INFLUENZA H5N8 FROM WILD BIRDS IN UKRAINE

Introduction. For today, highly pathogenic avian influenza is still among the major challenges for world poultry farming. Apart from economic losses caused by this disease to poultry industry, another important aspect is its hazard for human health, as well as potential risk of new pandemic virus to appear. Epizootic situation remains complicated last time,and outbreaks are registered in most countries with developed poultry farming.

The goals of the work is analytic data about three waves of highly pathogenic avian influenza in Ukraine over the last 10 years that had been caused by avian influenza viruses with various antigenic formulas H5N1 and H5N8.

Materials and methods. Sampling of wild birds was conducted January – December 2016 in the South regions of Ukraine. Biological material (fecal, internal organs) from wild birds (10 waterfowl species) were collected. Virus isolation and identification were carried out by standard methods recommended by the OIE.

Results of research and discussion. This paper presents Also, virologic research data is represented for 1438 samples of biological material, collected in 2016 from wild birds of 10 species in Azov-Black Sea region of Ukraine. 21 hemagglutinating isolate had been obtained from biological material, 8 of them belong to avian influenza and 13 are paramyxoviruses. As the result of virologic research of samples from dead wild birds (white-fronted goose and ruddy shelduck), as well as environmental samples, 4 highly pathogenic avian influenza H5N8 viruses had been isolated.

Conclusions and prospects for further research. Our results demonstrate the great genetic diversity of AIVs and APMVs in wild birds in Ukraine, as well as the importance of this region for the ecology of emergent pathogens, exchange of genes and introduction of new variants. Detection of HPAIV/LPAIV H5 confirm the importance to continue these studies within the One Health concept in order to timely prevent highly pathogenic viruses that pose a threat to poultry and human health.

Keywords: highly pathogenic avian influenza H5N8, wild birds, epizootologic monitoring.
