Torque teno sus viruses (TTSuV) were detected in the pig population in the Czech Republic by a nested PCR technique. The prevalence of individual TTSuV was found to be 42.9% (TTSuV1) and 46.7% (TTSuV2). The prevalence for TTSuV 1 and TTSuV2 was determined to be 52.7% and 60.6% in piglets at weaning, 90.9% and 63.6% in gilts, and 75% and 87.5% in sows, respectively. Both virus species were detected in 12% of newborn piglets, which suggests possible transplacental transmission. Sequencing of several virus strains showed that the sequenced TTSuV strains belong to two different species of viruses. The average similarity on the nucleotide levels between these two species was 43.3%.
在捷克共和国的猪群中，通过巢式 PCR 技术检测到 Torque teno sus 病毒（TTSuV）。发现个别 TTSuV 的流行率分别为 42.9%（TTSuV1）和 46.7%（TTSuV2）。断奶仔猪的 TTSuV1 和 TTSuV2 的流行率分别为 52.7%和 60.6%，后备母猪为 90.9%和 63.6%，母猪为 75%和 87.5%。在 12%的新生仔猪中同时检测到了这两种病毒，这表明可能存在胎盘传播。对几种病毒株进行测序表明，测序的 TTSuV 株属于两种不同的病毒种。这两个种之间在核苷酸水平上的平均相似度为 43.3%。
