Sow vaccination or infection status that results in high levels of IAV strain-specific maternally-derived antibodies may help to reduce IAV circulation in both suckling and nursery pigs.

The objective was to determine if the addition of a bench entry system in a commercial swine facility with a shower lowers the risk of personnel introducing environmental contamination.

In a PRRSV-endemic setting involving bacterial co-infections, an ABF production strategy may leave pigs at considerable risk of exposure to severe clinical disease.

Dietary supplementation of C. butyricum might be a suitable alternative to antibiotics and ZnO for weanling pigs.

This is, to our knowledge, the first report of a promising vaccine against ASF virus in wild boar by oral administration.

Group and environmental sampling strategies should be considered in influenza surveillance programs in particular if the goal is just to detect infection.

The findings of this study emphasize the importance of considering transmission of FMD during the incubation phase in modeling and response planning.

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.
