Torque teno sus virus infection in suckling piglets from Brazilian pig herds

Torque teno sus virus (TTSuV) is responsible for the infection of pig herds around the world. The aim of this study was to analyse the presence of natural infection by both species of TTSuV in suckling piglets from major pig-producing regions of Brazil. Faecal samples ( n = 135) from 1 to 3-week-ol...

Zusammenfassung:	Torque teno sus virus (TTSuV) is responsible for the infection of pig herds around the world. The aim of this study was to analyse the presence of natural infection by both species of TTSuV in suckling piglets from major pig-producing regions of Brazil. Faecal samples ( n = 135) from 1 to 3-week-old suckling piglets from the Southern, Southeast and Midwest regions of Brazil were analysed by PCR assay to detect TTSuV1 and 2. TTSuV1 and 2 DNA was identified in 65 (48.1 %) and 23 (17 %) of piglet faecal samples, respectively. Co-infection by both species of TTSuV was detected in 17 (12.6 %) samples. Detection of TTSuV1 was significantly higher than that of TTSuV2 in the three Brazilian regions together ( p
