Fig. 1From: The complexity of human infected AIV H5N6 isolated from ChinaPhylogenetic trees of HA (a) and NA (b) genes of AIV H5N6 and reference isolates. It demonstrated that AIV H5N6 isolates obtained from both human and poultry in China were very heterogeneous. Sequences labeled with red circles are current human infected isolates of AIV H5N6, with red triangles are the sequences of probable ancestors based on the current study, and with blue triangles are sequences of probable ancestors based on opinions from other researchersBack to article page
