The present study represents the first survey of Torque teno virus (TTV) prevalence in European wild boar (Sus scrofa). The prevalence of two distinct TTV genogroups in 178 Spanish wild boar sera from different geographic regions, management conditions, gender and age was determined by a nested PCR method. The overall prevalence of TTV genogroups was 84% (58% for genogroup 1 and 66% for genogroup 2), and differences between genogroup prevalence were observed depending on the geographical region analysed. Significantly higher prevalence for TTV genogroup 2 was found in fenced managed wild boar, juvenile animals and females. No other significant differences in TTV genogroup prevalence were observed. The phylogenetic analysis of nucleotide sequences obtained from the untranslated region of selected samples revealed that the same TTV genogroups are infecting wild boar and domestic pig. The results indicate that TTV is apparently ubiquitous in European wild boar populations.
本研究是对欧洲野猪（Sus scrofa）中细小病毒（TTV）流行情况的首次调查。采用巢式PCR方法，对来自不同地理区域、管理条件、性别和年龄的178份西班牙野猪血清中两种不同TTV基因组的流行情况进行了测定。TTV基因组的总体流行率为84%（基因组1为58%，基因组2为66%），根据所分析的地理区域，观察到基因组流行率存在差异。在围栏管理的野猪、幼年动物和雌性中，发现TTV基因组2的流行率显著更高。未观察到TTV基因组流行率的其他显著差异。对从选定样本的非翻译区获得的核苷酸序列进行系统发育分析表明，感染野猪和家猪的是相同的TTV基因组。结果表明，TTV在欧洲野猪种群中显然普遍存在。
