Maternally derived adaptive cellular immune responses play a critical role in protecting newborn piglets challenging PCV2 at 3 weeks of age.

Early administration of spray-dried animal plasma may stimulate feed intake in weanling pigs.

Two conditions must be fulfilled to diagnose PMWS in a herd: a significant increase in postweaning mortality and PMWS must be diagnosed in at least one of three to five necropsied pigs.

PCV2 vaccination was able to overcome this interference since the ADWG was improved.

PCV2 viruses were able to resist the regular wastewater treatment.

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.

The present study reflects the complex interaction among different pathogens and their effects in order to trigger PMWS in PCV2 infected pigs.

The model highlights the importance of the cost of subclinical cases, usually understimated.

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.

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

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

Effects of a PCV2 sublinical infection following an ADV vaccination.

The striking lesion found in the boar reproductive organs was edema of the epididymal head.

The objective of the current study was to evaluate cotton ropes for collection and detection of PCV2 specific antibodies and DNA in oral fluid at pen level in finisher pigs.

The concentrations of haptoglobin (Hp), C–reactive protein (CRP) and serum amyloid A (SAA) were measured in wasted pigs.

A total of 1279 Eurasian wild boar (Sus scrofa) sera were collected from 2000 to 2011 to reveal time changes in serum antibody prevalences against selected infectious agents (PCV2, PRRSV, HEV and Erysipelothrix rhusiopathiae.
