Research Abstract

We developed the analytical method of rapid and large sccale sequenging of hepatitis virus genome in the patients with the next generation sequencer Roche Genome Sequencer Junior(GSJ), and revealed the dynamic changes of viral quasispcies constitution during the treatment and disease progression by the analysis of HCV core, NS3, NS5A genes and HBV pre S gene through deep sequencing.
