Epidemiological comments

The USDA Animal Plant Health Inspection Service (APHIS) and the Missouri Department of Agriculture are conducting a comprehensive epidemiological investigation and have implemented enhanced surveillance and testing related to this event. Samples were initially collected from healthy, non-clinical turkeys as part of the routine, pre-slaughter surveillance that is done under the National Poultry Improvement Plan (NPIP) Avian Influenza Clean Program (H5 and H7). Through this routine surveillance H5N1 low pathogenic avian influenza (LPAI) of North American wild bird lineage was identified and confirmed by partial HA/NA sequence.
HA sequence is 98% similar to A/mallard/Ohio/11OS2229/2011(H5); amino acid sequence = NIPQRETR/GLFGAI. NA sequence is 99% similar to A/blue-winged teal/Louisiana/UGAI14-2494/2014(N1).
