This is the first report of RVH on swine farms in Europe including its characterization by means of complete genome sequencing.

Vaccine candidate ASFV-G-ΔI177L is able to induce protection against virulent Vietnamese ASFV field strains.

Replacement of antimicrobials by a Ligilactobacillus salivarius strain led to positive microbiological and biochemical changes in the enteric environment.

Pen-based oral fluid samples may be used to supplement the use of traditional samples for rapid detection of ASFV during ASF surveillance.

The stability of infectious ASFV is very low in acidic forest soils but rather high in sandy soils.

This study demonstrates the presence of virulent L. monocytogenes strains with virulent potential in pigs, with valuable implications in veterinary medicine and food safety.

Injection of pGLP-2 microspheres can be a therapeutic strategy for compensatory growth in intrauterine growth restricted piglets with low birthweights.

An evaluation and comparison of which specimen type: testicles, tails or udder wipes had the highest sensitivity at determining the litter PRRSv status compared to serum.

Swine inflammation and necrosis syndrome is influenced by husbandry and quality of sow in suckling piglets, weaners, and fattening pigs.

Medium-chain fatty acids and glycerol monolaurate inhibit ASFv in liquid conditions.

Results suggest that genetic selection of antibody response in commercial sows is possible, but with variable success.

EpiCC thresholds can be evaluated for predictive accuracy of protection in future efficacy studies.

The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control.

A study on the heterologous protection between Japanese Type 1 and Type 2 PRRSV isolates.

The methods derived from this study open up avenues to further investigate airborne transmission and risk of virus introduction into farms contributing to the control of diseases in swine.

The genetic determinants of infection identified in this work contribute to novel insights in S. suis pathogenesis and could serve as targets for novel vaccines or antimicrobial drugs.

Following tailor-made implementation of alternative measures, a substantial reduction of antimicrobial use in pig production was achievable without jeopardizing animal health.

Fecal microbiota transplantation from warthogs to pigs confers partial protection against attenuated ASFV strains.

The risk of ASFV transmission via contaminated crops is most likely low, if they are incubated for at least 2 hr minimum at room temperature.

Bioaerosol surveillance may be an effective non‐invasive surveillance approach to quickly disseminate data on multiple pathogens back to the farm stakeholders.

Senecavirus A (SVA) is the single member of the genus Senecavirus of the family Picornaviridae. A complete genome sequence of SVA strain GX2018-92 consisting of 7,280 nucleotides is reported.

A compound was identified that blocks the interaction between PRRSV and CD163, a macrophage-specific membrane scavenger receptor, potentially preventing infection.

Insufficient lactogenic protection provided by gilts plays a key role in the development of and the increased prevalence of clinical rotavirus C disease.

Currently, detection requires accessibility to infrequently available primary swine macrophage cultures. Here, we report the identification of a commercially suitable substrate for virus isolation of ASF virus.
