Fig. 1From: Molecular evolution of two asymptomatic echovirus 6 strains that constitute a novel branch of recently epidemic echovirus 6 in ChinaPolygenetic tree based on the CDS of EVs. a a tree was constructed based on the CDS of capsid coding region. b a tree was constructed based on the CDS of 3D gene. The two trees include all of the E6 strains with full CDS and some strains that have high similarity with K727 and K843. The black circles indicate the strains that we found, and the black triangles indicate the closest strains to K727 and K843Back to article page
