Abstract

Torque teno virus (TTV) is a novel hepatitis virus which is considered to be transmitted by the fecal-oral route. Wastewater samples were collected monthly from eight wastewater treatment plants in Japan for 1 year, from July 2003 to June 2004, and tested for the presence of TTV by TaqMan PCR. TTV was detected in 97% (93/96) of influent samples, implying that TTV is epidemic in Japan. TTV was also isolated in 18% (17/96) of secondary effluent samples before chlorination and in 24% (23/95) of final effluent samples after chlorination. There was no significant difference between the concentration of total coliform in TTV-positive final effluents and that in TTV-negative final effluents, which indicates that total coliform cannot be used as an indicator of TTV. No TTV was detected in 24 effluents for reuse from two wastewater treatment plants using sand filtration and ozonation.

摘要

输血传播病毒（TTV）是一种新型肝炎病毒，被认为通过粪-口途径传播。2003年7月至2004年6月期间，每月从日本的8个污水处理厂采集废水样本，为期1年，并通过TaqMan PCR检测TTV的存在。97%（93/96）的进水样本中检测到TTV，这意味着TTV在日本流行。在18%（17/96）的氯化前二级出水样本和24%（23/95）的氯化后最终出水样本中也分离出了TTV。TTV阳性最终出水中的总大肠菌群浓度与TTV阴性最终出水中的总大肠菌群浓度之间没有显著差异，这表明总大肠菌群不能用作TTV的指示指标。在使用砂滤和臭氧处理的两个污水处理厂的24份回用出水中未检测到TTV。
