目的 研究海南黎族人群TTV感染情况。方法 采用巢式PCR检测血清中TTV DNA,并对2株TTV的部分基因序列进行测定。结果 海南省黎族人群TTVDNA阳性率为8.5%,其基因序列与国内外报导的主要序列核苷酸同源性为98%。讨论 海南黎族人群存在TTV感染。
Objective To study the TTV infection in Hainan Li population. Methods TTV DNA in serum was detected by nested PCR and the partial gene sequences of two strains of TTV were determined. Results The positive rate of TTVDNA in Hainan population was 8.5%. The nucleotide sequence of the gene was 98% homologous to that reported in China and abroad. Discuss the TTV infection in Hainan Li population.
