Figure 2From: An outbreak of aseptic meningitis caused by coxsackievirus A9 in Gansu, the People's Republic of ChinaDendrogram illustrating sequence relationships among the studied CVA9 isolates and the prototype strains of Human enterovirus. The phylogenetic tree constructed based on analysis of VP1 gene was drawn by bootstrap analysis (500 times) using the Neighbor-joining of MEGA 4.0 software. The triangle in the figure showed strain Gansu05-1/GS/CHN/2005 was sequenced in this study.Back to article page
