Fig. 3From: ISU FLUture: a veterinary diagnostic laboratory web-based platform to monitor the temporal genetic patterns of Influenza A virus in swineThe combination of hemagglutinin clade (y-axis) and neuraminidase clade (x-axis) pairings in influenza A virus (IAV) isolates sequenced at the Iowa State University Veterinary Diagnostic Laboratory (ISU VDL). (a) From May 1 of 2014 and January 1 of 2015, the human-like HA in swine was primarily paired with the N1 classical clade. (b) After January 1 of 2015, there was a switch to a predominant pairing of the human-like H3 with the N2.2002 NA and a subsequent proliferation of the human like HABack to article page
