Torque teno virus (TTV) is frequently detected in humans, livestock and some companion animals. Very little is known about presence of TTV in Canadian livestock and the goal of this study was to evaluate the presence of TTV in swine and cattle using molecular tools. TTV DNA was detected and confirmed by sequencing in the plasma of 90.5% and in the feces of 60.3% of the animals tested in a single swine herd as well as 80.9% and 1.1% in the plasma of individuals from general Quebec swine and cattle populations, respectively. The impact of the TTV presence in livestock population for the agri-food chain should be further investigated.
环曲病毒(TTV)在人类、家畜和一些伴侣动物中经常被检测到。人们对加拿大牲畜中TTV的存在了解甚少,本研究的目的是使用分子工具评估猪和牛中TTV的存在情况。在一个猪群中,检测的动物血浆中有90.5%以及粪便中有60.3%检测到并经测序确认有TTV DNA;在魁北克省一般猪和牛群体的个体血浆中,这一比例分别为80.9%和1.1%。TTV在牲畜群体中对农业食品链的影响有待进一步研究。
