【摘要】 目的　了解不同人群输血传播病毒 (TTV)的感染状况。方法　采用套式PCR法检测血清标本中TTVDNA ,并对其中 1株TTV的部分基因序列进行了测定。结果　不同人群TTVDNA阳性率分别为 :正常体检人群 10 .3% ,献血员 43.7% ,吸毒者 15 .6% ,血液透析病人5 4.4% ,妓女 65 .0 % ,慢性丙型肝炎病人 2 5 .0 % ,非甲～庚型肝炎 0 / 11。结论　TTV在各类人群中均有较高的感染率更多还原

【Abstract】 Objective To investigate the prevalence of transfusion transmitted virus (TTV) in different populations of China. Methods TTV DNA was detected in sera collected from different populations by nested PCR. Partial gene of a TTV isolate was directly sequenced. Results The prevalences of TTV in various populations were as follows: 10.3 % (31/301) in general population when receiving physical checkup; 43.7 % (14/32) in blood donors; 15.6 % (5/32) in intravenous drug addicts; 54.4 % (6/11) in hemodialysis patients; 65% (13/32) in prostitutes; 25% (4/16) in patients with chronic hepatitis C. None of the 11 patients with non A-G hepatitis was detected TTV DNA. Conclusion High prevalence of TTV infection was found in different populations of China.更多还原
