Researchers of the CReSA have described for the first time antigenic sites of PRRSV that are recognized by T cells, using bioinformatics tools and later immunological analysis. All these information is relevant for the design of newer and better vaccines.

A real-time PCR assay, based on Primer-Probe Energy Transfer (PriProET), was developed to improve the detection and quantification of porcine circovirus type 2 (PVC2).

In this study, we focused on establishing a challenge model for PCV2 to determine whether SIV influences PCV2 replication and increases the severity of PCV2-associated disease.

This paper compares the effectiveness of two Dutch incentive mechanisms: a collective insurance – in place prior to July 2004 – and a reduction in producer payment for each delivered pig with a liver lesion – in place from July 2004.

The present study reports the detection of PCV2, the pathogenic form of the virus, in mice and rats.

Salmonella Typhimurium strains associated with septicemia belong to various genetic lineages that can also be recovered from asymptomatic animals at the time of slaughter.

This study confirms the hypothesis that PCV2 plays a role in pneumonia and pleurisy in 10-24 weeks old fattening pigs, not only in herds with a high prevalence of PMWS, but also in herds with no clinical signs of PMWS.

To investigate the transition in concentration of porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) and antibody for these viruses in serum, serum samples were collected from 29 pigs on weaning day and at 7, 14, 21, 28, 53, 84, and 120 days after weaning.

The effects of different pre-slaughter feed withdrawal times (FWT) on the gastrointestinal tract (GIT) weight and the gut environment of pigs and Salmonella shedding were investigated.

Quantitative analysis of the duration of foot-and-mouth disease virus (FMDV) RNA in tissues was carried out in pigs experimentally infected with FMDV O UKG 34/2001 and O SKR 1/2000.

An experiment was performed to investigate the effects of seaweed extracts, laminarin (derived ß-glucans) and fucoidan (sulphated polysaccharides) independently or in combination on post-weaning piglet performance and selected microbial populations.

Results of this study suggest for the first time occurrence of PPV and coinfection with PCV2 in crossbred Indian pigs affected with reproductive problem and neonatal mortality.

Invasion of endothelial cells is a virulence mechanism of H. parasuis that may be related to the ability of some strains to cause meningitis.

This study provides the first proof of concept for the prophylaxis/treatment of CSFV infection in pigs.

The cause of PWCS is unknown. Clinically, PWCS waxes and wanes in affected farms, and is not predictable. The majority of pigs with PWCS die, increasing mortality in 3 to 9 week old pigs from 1-2% to 6-10% on most affected farms.

Escherichia coli was isolated from the feces of 122 piglets with diarrhea on 55 farms in Korea. The virulence genes of each isolate were characterized by polymerase chain reaction (PCR).
