Intranasal inoculation with ASF virus genotype II reveals dose-dependent infectivity, pathogenesis and diagnostic challenges in pigs

The results of this work support the relevance of both molecular and serological diagnostic strategies for ASF control.

A multi-host mechanistic model of African swine fever emergence and control in Romania

Interspecific transmission was a critical epidemic driver and a necessary target for achieving holistic control.

333 Emerging Voices - Pathological findings in pigs affected by inclusion body rhinitis

This work evaluates the relationship of inclusion body rhinitis in pigs with other findings observed in necropsies. Final thesis at the Veterinary Pathology Diagnostic Service of the Faculty of Veterinary Medicine, UAB, Spain, advised by Joaquim Segalés.

Infection prediction in swine populations with machine learning

Models provide daily infection probabilities that can be used as a benchmark to more timely support preventive and control strategies on farms.

Characterization and cross-protection of SeCoV and two PEDV variants

In homologous re-challenged pigs, no clinical signs or lesions were observed, while prior exposition to a different PEDV G1b variant or SeCoV only provided partial cross-protection.

Water consumption and wastage behaviour in pigs: implications for antimicrobial administration and stewardship

The study shows it is feasible to use a system to quantify the water use and wastage patterns of pigs in farm buildings.

Histological lesions and replication sites of PCV3 in pigs

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.

Effect of strain-specific maternally-derived antibodies on influenza A virus infection dynamics in nursery pigs

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.

Performance of pigs raised in antibiotic-free or conventional production systems following challenge with PRRSV

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.

Sampling strategies to conduct influenza surveillance in pigs

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

Evolution in Europe of ASF genotype II viruses from highly to moderately virulent

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.

Infectious dose of ASFV when consumed naturally in liquid or feed

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.

Alternative sampling strategies for passive CSF and ASF surveillance in wild boar

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

Epidemiological surveillance of Mycobacterium tuberculosis complex in extensively raised pigs in the south of Spain

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

PCV3 is highly prevalent in serum and tissues and may persistently infect wild boar

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

Herd‐level prevalence and incidence of PEDV and PDCoV in swineherds in Ontario

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.
