【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 16 9例乙型肝炎病毒感染者中检出血清TTVDNA阳性者 2 3例 ,阳性率 13 6 1%。其中 ,急性乙型肝炎患者组阳性率 13 46 % ,慢性乙型肝炎患者组阳性率 15 0 7% ,HBsAg携带者组阳性率 11 36 % ,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 Twenty three(13 61%)were found to be TTV DNA positive. TTV DNA positive rates in acute and chronic hepatitis B patients and in HBsAg carriers were 13.46, 15.07 and 11 36%, respectively. No significant difference (P>0.05)was noted among the three groups. Conclusion TTV infection is found in our contry. Its pathogenicity remains to be studied.更多还原
