Comparison of Torque Teno Sus Virus (TTSuV) viral load in Porcine Circovirus Type 2 vaccinated and non-vaccinated pig herds.

Torque Teno Sus Virus (TTSuV) viral load in accordance with the Porcine Circovirus Type 2 (PCV2) infection and age of two pig herds was determined. A total of 100 and 155 piglets from two farms were divided into two groups. Half of the piglets from each farm were given a commercial vaccine against PCV2 (vaccinated group), and the remaining piglets were used as a control group (non-vaccinated group). An early onset and a chronic viremic state of TTSuV genogroups were present regardless of the PCV2 infection, and there were no significant differences in the dynamics of TTSuV genogroups.
