High frequencies of HGV and TTV infections in blood donors in Hangzhou

Figure 1 Target amplification fragments from HGV RNA and TTV DNA. (1: marker; 2 and 3: HGV positive serum samples; 4: blank for HGV detection; 5 and 6: TTV positive serum samples; 7: blank for TTV detection)

Figure 2 Homology of the nucleotide sequences from HGV RT-nested PCR products from 3 serum samples as compared with the reported sequence. (1. The reported HGV sequence[13] ; 2-4. The sequences of HG V RT-nested PCR products from 3 serum samples. Underlined areas indicate the primer positions.)

Figure 3 Homology of the nucleotide sequences from TTV semi-nested PCR products from 3 serum samples as compared with the reported sequence. 1. The reported TTV sequence[40]; 2-4. The sequences of TTV semi-nested PCR products from 3 serum samples. Underlined areas indicate the primer positions.
