Recombinant Ad5-O1Man is an effective, safe and cross-reacting vaccine that could potentially be used preventively and in outbreak situations, to control FMDV O Mya-98 lineage in swine.

Dietary supplementation with microalgae as an alternative to antibiotic use was studied.

These results further demonstrated the potential use of oral fluids for detecting FMDV genome, live virus, and viral antigens.

It is important to study the diversity of the strains of Yersinia enterocolitica in order to better understand the risk they represent for humans.

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

This study showed a massive occurrence of ST398-MRSA in two independent swine farms.

This study expands existing knowledge on the genetic diversity and evolution of PRRSV in Vietnam.

We studied the change in amounts of antimicrobials prescribed for weaners and finishers in Danish herds duriong 2007-2013 following initiation of vaccination against five common endemic infections.

This study implies a metabolic adaptation of A. pleuropneumoniae to the porcine upper respiratory tract already during early infection.

Researchers from the IRTA-CReSA in collaboration with researchers from the Erasmus University Medical Center Rotterdam (the Netherlands), studied the susceptibility of different animal species to infection with MERS-CoV.

There is an increasing concern in several European countries over the role that tuberculosis (TB)-infected wild boar may play in the progress of bovine TB eradication campaigns. In Spain, the wild boar is the main wild reservoir of tuberculosis.

Results indicate that B. hyodysenteriae has a high degree of serological heterogeneity that has probably differently developed in diverse geographical areas over time.

The LAMP assay established in this study provides a simple, specific, sensitive and rapid method of T. gondii genomic DNA detection, hence is expected to plays an important role in the monitoring of T. gondii contamination in various food products.

This review summarizes data on the types of occupation-related infections caused by LA-MRSA CC398, the incidence of such infections as well as potential preventive strategies.

The study provided the first known report of clinical lung lesions and endocarditis in piglets due to Staphylococcus sciuri.

This study showed that oral fluid-based testing could provide an easy and “animal-friendly” approach to sample collection for nucleic acid and/or antibody-based surveillance of PEDV in swine populations.

Results from this study can help determine timing of antimicrobial use and contribute to our current understanding of judicious antibiotic use.

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.

Precision engineering for PRRSV resistance in pigs: Macrophages from genome edited pigs lacking CD163 SRCR5 domain are fully resistant to both PRRSV genotypes while maintaining biological function

This work could inform contingency planning that would lead to cost savings in the event of a future FMD outbreak and could also be applied to other infectious diseases.

African swine fever (ASF) is a major pig health problem, and the causative virus is moving closer to Western European regions where pig density is high. Stopping or slowing down the spread of ASF requires mitigation strategies that are both effective and practical.

Feed additives that contained phosphoric acid, citric acid, or fumaric acid were the most effective in reducing virus survival.

We detected a recently discovered pestivirus, termed atypical porcine pestivirus (APPV) in all these cases by RT-PCR.

These studies are the evidences that indirect transmission of PEDV through contaminated personnel, which occurs rapidly, and how fomite material and temperature impact viral stability over time.
