Fig. 1From: Characteristics of influenza H13N8 subtype virus firstly isolated from Qinghai Lake Region, ChinaPhylogenetic trees of HA, NA and PB1 of two H13N8 viruses, .a) H13 gene b) N8 gene c) PB1 gene. Three segment full sequences were used to conduct phylogenetic tree using MEGA 7 with 1000 neighbor-joining replicates. Two H13N8 viruses isolated in Qinghai lake region are indicated by filled circlesBack to article page
