Abstract:
Objective To analysis the diverse of transfusion transmitted-virus(TTV)carrier ratio between HBsAg positive and HBsAg negative people and to anlaysis the TTV nucleic acid sequence.
Methods Nested-PCR was applied to amplify TTV nucleic acid, then to analysis the TTV nucleic acid sequence and construct the evolution tree.
Results There was no significant diversity HBsAg positive and HBsAg negative people in TTV carrier ratio.Shenzhen TTV was more homologous with TTV found in Japan.
Conclusion There is no relativity between TTV carrier ratio and HBsAg carrier ratio.
