[TD]The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Departments of Agriculture and Wildlife, are continuing to conduct a comprehensive epidemiological investigation and enhanced surveillance (including wild bird surveillance of hunter harvested birds) in response to the HPAI H5N8 and H5N2 wild bird related events. Novel avian influenza virus of Eurasian origin (EA-H5N8 clade 2.3.4.4) spread rapidly along wild bird migratory pathways during 2014. Introduction of this EA-H5N8 virus into the Pacific Flyway sometime during 2014 has allowed mixing with North American (AM) lineage viruses and generated new combinations with genes from both EA and AM origin (or ?reassortant? viruses) such as this EA/AM H5N2-reassortant detected in Canada and the US. These findings are not unexpected as the EA-H5N8 virus continues to circulate. The EA-H5 clade 2.3.4.4 viruses are highly pathogenic for poultry. On 8 & 9 March 2015, the USDA APHIS National Veterinary Services Laboratories (NVSL) confirmed HPAI EA/AM H5N2 positive results from two commercial turkey flocks. One turkey flock in Jasper County, Missouri, and one turkey flock in Moniteau County, Missouri. Partial HA/NA sequence is >99% similar to A/northern pintail/Washington/40964/2014 based upon direct sequence attempt from turkey swab specimen. These are the first detections of HPAI EA/AM H5N2 in Missouri. On 11 March 2015, the USDA APHIS National Veterinary Services Laboratories (NVSL) confirmed HPAI EA/AM H5N2 positive results from a commercial turkey flock in Boone County, Arkansas. Partial HA/NA sequence is >99% similar to A/northern pintail/Washington/40964/2014 based upon direct sequence attempt from turkey swab specimen. This is the first detection of HPAI EA/AM H5N2 in Arkansas.[/TD]
