Seropositive wild boar in certain areas suggests that some animals may be surviving for some time or could even be recovering from the disease. This could be due to the presence of related viruses of reduced virulence.

Although greater concentrations of ASF virus were required to cause infection through feed, the high frequency of exposure may make contaminated feed a more significant risk factor.

Autogenous vaccination reduces antimicrobial usage in a herd facing severe exudative epidermitis outbreaks in weaned pigs.

Fallen wild boar are the main target for passive surveillance. However, encouraging reporting by hunters and sampling of these animals is difficult.

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.

The study demonstrated that RNA interference (RNAi) technology combining CRISPR/Cas9 technology offered the possibility to produce TG animal with improved resistance to viral infection.

The efficacy of the attenuated PRRSV-1 vaccine in 1-day-old pigs seropositive to PRRSV prior to a PRRSV-1 challenge was demonstrated by improvement of clinical, virological and immunological variables.

ATP bioluminescence method can be used as a supplementary tool for monitoring surface cleanliness of transport trailers in a rapid, simple, inexpensive and reliable way.

Iberian pigs could act as reservoir of tuberculosis (TB) in Mediterranean ecosystems.

Wild boar is susceptible to PCV‐3 infection, showing high frequency of detection in this animal species.

Survival of African Swine Fever virus in excretions from pigs experimentally infected with the Georgia 2007/1 isolate.

The total acquired AMR level was associated with the overall country-specific antimicrobial usage in livestock and that countries with comparable usage patterns had similar resistomes.

The study provides preliminary evidence that when comparing Salmonella-inconspicuous farms with Salmonella-conspicuous ones, the colostrum supply may be a critical factor that needs to be considered.

Parenteral antimicrobial administration shifts the nasal microbiota in growing piglets. The changes in nasal microbiota structure were antimicrobial-dependent. Rationalization of injectable antibiotic treatments in growing piglets is needed.

Porcine epidemic diarrhoea virus (PEDV) and porcine deltacoronavirus (PDCoV) were first identified in Canada in 2014. Surveillance efforts have been instrumental in controlling both diseases.

Composting appears to be an effective disposal method for PEDV-infected piglet carcasses under the conditions examined.

This study systematically reviewed available measures to prevent the spread of ASF in the EU domestic pig sector distinguishing between commercial, non-commercial, and outdoor farms.

The goal of this project was to compare the accuracy of oral-fluids and over-the-shoe booties to the current gold standard of fecal sampling for identification of Salmonella in pigs.

The systematic monitoring of production indicators using EWMA offers opportunity to early detect outbreaks and/or to quantify the production losses attributed to PRRS infection.

The results of the present study demonstrated that the P. multocida isolated from diseased pigs in Taiwan was resistant to multiple antimicrobials.

The results of this study provide clinical information on how to reduce seminal shedding of type 1 PRRSV in boars using type 1 PRRSV-modified live vaccine.

This study highlights the importance of identifying coronavirus diversity and distribution in bats.

Results provide further evidence that contaminated feed ingredients may represent a risk for transport of pathogens at domestic and global levels.

This study aims to develop a cost-effective, non infectious CSF subunit vaccine that can elicit rapid and long lasting immunity.
