Figure 3. Schematic representation of the reassortant highly pathogenic avian influenza A virus subtypes H5N8 and H5N5 detected in the Netherlands, 2016. The Russia-Mongolia ancestor is shown in green. NL clusters 1 (blue) and 2 (red) viruses obtained novel PB2 and NP gene segments and 2 different PA segments. Two genetically distinct H5N5 viruses were detected, 1 in a tufted duck in Werkendam (pink) and 1 in a mute swan near Groningen (purple). HA, hemagglutinin; MP, matrix protein; NA, neuraminidase; NL, Netherlands; NP, nucleoprotein; NS, nonstructural protein; PA, polymerase acidic; PB1, polymerase basic 1; PB2, polymerase basic 2.
