Simultaneous PCV2 and Mycoplasma hyopneumoniae co-inoculation does not potentiate disease in conventional pigs

Under the conditions of the present study, concurrent inoculation of PCV2 and Mhyo did not result in potentiation of clinical signs and lesions attributed to either infection.

Update on the diseases associated with the PCV2: clinic, diagnosis and control

The PCV2 has been associated, in an ongoing way and throughout time, with more pathologies called, collectively, diseases associated with the PCV2 (PCVDs): PCV2 systemic disease, PCV2 lung disease, PCV2 enteric disease, PCV2 reproductive disease,PCV2 subclinical infection and porcine dermatitis and nephropaty syndrome.

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.
