Preliminary study of Porcine circovirus type 2 and Torque teno sus virus coinfection frequencies in Brazilian pig herds

Given the limited information on TTSuV and PCV2 coinfection, especially in Brazilian swine herds, this study made a preliminary estimation of the occurrence of coinfection in swine herds by testing samples from different categories.

Effect of the viraemia due to the porcine circovirus type 2 (PCV2) on production parameters

The most effective way of avoiding the production losses associated with the PCV2 consists in avoiding the appearance of the viraemia by inducing a passive or an active immunity that minimizes the circulation of the virus in the farm.

Abstract

Fetal infections and antibody profiles in pigs naturally infected with porcine circovirus type 2 (PCV2)

In conclusion, even on farms with sows that have high PCV2 antibody titers, vertical transmission of PCV2 may occur, resulting in piglet infection.

Abstract

Torque Teno sus virus type 2 (TTSuV2) loads in serum are increased in the background of diseases affecting the immune system

These studies indicate that TTSuV2 load in serum is up-regulated in PCVD and CSF, while this did not happen with TTSuV1.
