Detection of Torque teno sus virus (TTSuV) in pigs

Abstract

The study “Detection of Torque teno sus virus (TTSuV) in pig” was conducted in an industrial pig farm from January, 2015 to March, 2016. PCR technique was applied to determine the presence of TTSuV and a co-infection of TTSuV and PCV2 in the pig tissue and serum samples. The studied result indicated that the pigs in this farm were infected with TTSuV1 and TTSuV2 with the increasing tendency by the age groups. The TTSuV2 prevalence of the PCV2-infected pigs was higher than that of the non-PCV2-infected pigs. There was not significant difference on TTSuV1 prevalence between the PCV2-infected and non-PCV2-infected pigs. Furthermore, both TTSuV1 and TTSuV2 were found in all of the studied organs including blood, lung, liver, spleen, tonsils and inguinal lymph nodes. The highest prevalence of TTSuV1 and TTSuV2 was found in the liver and spleen. TTSuV1 prevalence of the non-PCV2 infected pigs was higher than that of the PCV2 infected pigs; meanwhile, the TTSuV2 prevalence was similar in both pig groups.
