【摘要】 目的　研究乙型肝炎病毒 (HBV)感染者重叠感染输血传播病毒 (TTV)的状况。方法　采用斑点杂交法检测乙型肝炎病毒感染者血清TTVDNA。结果　在 364例乙型肝炎病毒感染者中检出血清TTVDNA阳性者 82例 ,阳性率 2 2 .53 %。其中 ,急性乙型肝炎患者组阳性率 2 3 .2 1 % ,慢性乙型肝炎患者组阳性率 2 6 .2 5 % ,HBsAg携带者组阳性率 1 5 .2 2 % ,三者之间的差异无统计学意义P >0 .0 5。结论　在我国存在TTV感染 ,但其致病性值得进一步探讨更多还原

【Abstract】 Objective To investigate the events of transfusion transmitted virus(TTV) infection in the patients with HBV. Method The serum TTV DNA was detected by dot blot hybridization. Results 82 (22.53%)cases were found to be TTV DNA positive. TTV DNA positive rates in acute and chronic hepatitis B patients and in HBsAg carriers were 15.22%, 23.21% and 26.25%,respectively. No significant difference (P>0.05) was noted among the three groups. Conclusion TTV infection is found in our country. Its pathogenicity remains to be studied.更多还原
