摘要：

In this study, 40 pigs with respiratory and wasting disorders from Cuban swine herds were screened by PCR for the presence of TTSuVI, TTSuV2, PCV-2, PPV and CSFV in spleen samples. The variability of the porcine TTSuV sequences obtained was investigated by phylogenetic analysis. This study showed for the first time that TTSuVI and TTSuV2 were present in Cuban swine herds. The investigation revealed the following infection rates: TTSuVI 40%, TTSuV2 37.5%, PCV-2 70%, PPV 37.5% and CSFV in 52.5%. The presence of two or more of these viruses at different rates in the same spleen samples was revealed. Also, a higher genetic diversity of TTSuV2 sequences was observed regarding TTSuV1 sequences.
