Toward a Unified Nomenclature System for Highly Pathogenic Avian Influenza Virus (H5N1)

WHOOIEFAO HNEvolution Working Group1

Main Article

Figure 2

Neighbor-joining tree of 158 H5N1 isolates constructed by using PAUP* version 4.0b10 (9). Estimates of the phylogenies were calculated by performing 1,000 neighbor-joining bootstrap replicates. Distinct amino acid residues shared only by isolates within a particular clade are shown on the line above the clade-defining node when present. Amino acid substitutions represent change relative to Gs/GD/1/96. The small tree was rooted at the clade 0 node for larger scaling. Scale bar represents 0.01-nt

1The working group was established by request of the World Health Organization’s Global Influenza Programme, Department of Epidemic and Pandemic Alert and Response (WHO, GIP, EPR), the World Organisation for Animal Health (OIE), and the Food and Agriculture Organization (FAO). It consisted of the following members: Ruben O. Donis, Centers for Disease Control and Prevention (CDC), Atlanta, Georgia, USA (co-chair); Gavin J.D. Smith, University of Hong Kong, Hong Kong Special Administrative Region, People’s Republic of China (co-chair); Michael L. Perdue, WHO, GIP, EPR, Geneva, Switzerland2 (coordinator); Ian H. Brown, Veterinary Laboratories Agency, Addlestone, UK; Hualan Chen, Harbin Veterinary Research Institute, Chinese Academy of Agriculture Sciences CAAS, Harbin, People’s Republic of China; Ron A.M. Fouchier, Erasmus University, Rotterdam, the Netherlands; Yoshihiro Kawaoka, University of Wisconsin-Madison, Madison, Wisconsin, USA, and Institute of Medical Science, University of Tokyo, Tokyo, Japan; John Mackenzie, Curtin University of Technology, Perth, Western Australia, Australia; and Yuelong Shu, China Centers for Disease Control, Bejing, People’s Republic of China. In addition, the following persons made substantial contributions: Ilaria Capua, Instituto Zooprofilattico Sperimentale delle Venezie, Padova, Italy; Nancy Cox, Todd Davis, Rebecca Garten, and Catherine Smith, CDC; Yi Guan and Dhanasekaran Vijaykrishna, University of Hong Kong; Elizabeth Mumford, WHO, GIP, EPR; and Colin A.
