Abstract
We determined the complete genome sequences of torque teno sus viruses (TTSuVs) detected in pigs with postweaning multisystemic wasting syndrome (PMWS) and in healthy pigs in Japan. Unexpectedly, we found coinfection of a PMWS-affected pig in Japan with one strain of TTSuV1, five strains of TTSuV2, and one strain of PCV2. Full-genome sequencing of each of these strains, followed by phylogenetic analysis, revealed broad genetic diversity in the TTSuV2 strains infecting the PMWS-affected pig. These results suggest that the geographical bias in the available genetic information about TTSuVs has a limited impact on the evaluation of their genetic diversity.
