摘要: DNA sequences of a novel virus (TTV) were examined in 81 peripheral blood mononuclear cell (PBMC) samples from 48 children and 33 adults, 22 cord cells (CBMC) samples, 7 autopsy liver tissue by hemi-nested polymerase chain reaction (PCR). The PCR was carried out using the published primers (NG059, NG061, NG063) to amplify TTV sequences. detected 4 (5%) PBMC none (0%) CBMC 2 (29%) direct gel analysis. PCR-amplified products confirmed sequencing. sequencing showed considerable diversities, with differences 0-55% 6 isolates, compared prototype sequence TTV. These results suggest that is ubiquitous produces asymptomatic infection large proportion general population without transfusion blood-derived products. To our knowledge, this first report describing detection PBMCs.
