输血传播病毒(TTV)是一种具有在感染个体血液中广泛存在而又缺乏明显病理特征的人类DNA病毒,世界各国相继报道了其高流行率。Takahashi等报道,在日本志愿者血浆中发现的新病毒与TTV相关却又有明显区别,其体积小(<20或30～50nm)、序列短(约2.9～3.8kb),故命名为TTV样细小病毒(TLMV)。为对TTV及其相关病毒有更深入的了解,作者进行了该实验。 Transfusion-transmitted virus (TTV) is a human DNA virus that has widespread in the blood of infected individuals and lacks obvious pathological features. Countries around the world have successively reported their high prevalence. Takahashi et al. Reported that the new virus found in the plasma of Japanese volunteers is significantly different from TTV in that it is small in size (<20 or 30-50 nm) and short in sequence (about 2.9-3.8 kb) Parvovirus (TLMV). In order to have a deeper understanding of TTV and its related viruses, the authors conducted this experiment.
