Approaches to ASF vaccinology and the key constraints involved in the scale-up and commercialization of vaccine candidates.

This study demonstrated the presence of multiple PRRSV lineages, sub-lineages, and variants in swine herds and its potential association with swine reproductive performance under field conditions.

Preliminary results displayed a great potential for disease detection and characterization using salivary biomarkers profiling.

It may take two weeks or longer to detect ASF in a finisher swine herd via mild clinical signs or increased mortality.

Farmers could achieve and maintain the Raised Without Antibiotics status through farm-specific coaching related to prudent antimicrobial usage and improved biosecurity.

This is the first report of the detection and genetic characterisation of the PCV-2e genotype in Europe, from sows on a farm in Italy.

Viral pathogens of pigs can survive in representative volumes of feed and feed ingredients during long-distance commercial transport across the continental United States.

Results emphasize the need to implement surveillance and transmission preventive protocols at the pig/human interface.

Feed matrices are able to extend the survival of Senecavirus A and consumption of contaminated feed can lead to productive Senecavirus A infection.

This paper aims to provide recommendations to design a search strategy to find ASF-infected wild boar carcasses.

This study investigated the association between the presence of PCV3 mRNA detected by in situ hybridization within histological lesions and PCV3 DNA detected by real-time PCR in naturally infected pigs.

The effects of different boars from the Duroc and Pietrain breeds on the prevalence of swine inflammation and necrosis syndrome in their offspring.

Superficial inguinal lymph nodes can be collected in minutes with no to minimum environmental contamination.

Wild boars were found to be a reservoir of a highly virulent clone of hybrid Shiga toxigenic and enterotoxigenic Escherichia coli responsible for edema disease.

Sequencing results suggest that this represents the emergence of a new variant within Lineage 1C distinct from what has been previously circulating.

ASF virus became widely distributed throughout the facility with only minor changes in detection frequency as subsequent batches of feed were produced.

The thermostability of lyophilized live-attenuated CSFV vaccine formulations were investigated.

The emergence of genotype I ASFVs in China will present challenges in controlling the disease.

The presence of Salmonella in free-range pigs is directly related to the natural vegetation accessible, determining the composition of the intestinal microbiota.

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.
