articles about PCV2 in Abstracts

The suggested classification can establish a "common language" for future studies, further efforts should be paid to achieve a more homogeneous and informative representation of the PCV-2 global scenario.

This study set out to describe detection patterns of porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), swine influenza virus type A (SIV) and Mycoplasma hyopneumoniae (M. hyo) among farms showing differing severity of PRDC.

The purpose of the study was to evaluate the effect of vaccination against PCV2 in a sub-clinically infected, high-health finishing herd in terms of viral load in serum, feed conversion ratio and antimicrobial treatments.

The need for developing PCV2-specific ELISA methods is urgent to evaluate PCV2 antibody level in exclusion of PCV1 antibody interference after PCV2 vaccination.

In all three cases we characterized the genome of a new circovirus we called PCV3.

Here, a novel porcine circovirus (PCV3) that is distantly related to known circoviruses was identified in sows with porcine dermatitis and nephropathy syndrome (PDNS) and reproductive failure.

This study was aimed at evaluating the clinical protection, the level of Porcine circovirus type 2 (PCV2) viremia and the immune response (antibodies and IFN-γ secreting cells (SC)) in piglets derived from PCV2 vaccinated sows and themselves vaccinated against PCV2 at different age, namely at 4, 6 and 8 weeks.

The data present bronchial scraping as an equally effective or even better alternative to bronchoalveolar lavage fluid for detecting main porcine respiratory disease complex agents.

In the presence of high MDA levels, piglets immunized with four commercial PCV2 vaccines showed a significantly reduction of PCV2 infected pigs, viral load...

The estimated impact of PCV-2 vaccination revealed a highly significant decline in total antimicrobial drug use on finishing farms.

Since the introduction of PCV2 vaccines in 2006, viral presence and viral loads have greatly decreased, and a genotypic shift dominated by PCV2b has occurred.

Under the conditions of this study, it makes no difference to protection whether PCV2 and PRRSV vaccines are administered concurrently. Concurrent vaccination is efficacious for controlling co-infection with PCV2 and PRRSV.

The indirect ELISA that we developed with rctCap, the recombinant capsid fragment containing the 217–342 nt repeat domain, was sensitive, specific, and suitable for the large-scale detection of P1 infections in swine.

The results presented here demonstrate a possible use for recombinant S. cerevisiae expressing viral proteins as an oral vaccine against PCV2.

The results from this herd indicated that PCV2 vaccination may reduce the PCV2 infection level even during an acute outbreak of PRRS, but the results also showed that PCV2 vaccination does not eradicate the virus from the herd. Further studies are needed to draw general conclusions on this matter.

The defined subpopulations of piglets were observed in all experimental groups (NV–NV, NV–V, V–NV and V–V) although in variable percentages.
