Abstract excerpt
OBJECTIVE: To analyse the distribution of TT virus (TTV) genotypes in the blood donors of Northern China. METHODS: TTV DNA was detected using nested-PCR and its PCR products were cloned into the pGEM-T vector for sequencing. The sequences were analysed using ClustalX and Neighbor joining programs. RESULTS: Nucleotide identity of the 12 strains of Chinese TTV isolated was 53%-95%. Nucleotide homology between the...
