摘要
为调查输血传播病毒(TTV)在我国猪群中的感染状况,本研究对2009年采自29个省市的1 990份猪血清样品进行了TTV1、TTV2的双重PCR方法检测,并对结果进行了统计分析。结果表明,我国猪群中TTV总的感染率为63.37%(1261/1990),其中TTV1感染率为55.88%(1 112/1 990),TTV2为32.91%(655/1 990),TTV1和TTV2双重感染率为25.43%(506/1 990)。进而对样品的地区性分布特征、样品来源等影响因素进行分析,表明我国猪群中TTV感染率以东北地区最高,西北地区最低。样品来源不是影响感染率的关键因素。
To investigate the prevalence and distribution of Torque teno virus （TTV） in swine herds in China, a total of 1,990 swine serum samples were collected fi＇om 29 provinces in 2009, and detected using a duplex PCR assay for detection of TTV1 and TTV2. The results indicate that total of swine TTV positive was 63.37% （1261/1990）, and it was 55.88% （1112/1990） for TTV1, 32.91% （655/1990） for TTV2 and 25.43% （506/1990） for TTV1 and TTV2 co-infections. Statistical analyses demonstrated that the highest positive rate of swine TTV was found in Northeast China and the lowest rate in Southeast China. Geographic origin of samples was not a critical factor for the prevalence of TTV.
