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%.
