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.

For this trial, dry disinfectant was the most efficacious in reducing the viral RNA on both boots and subsequent surfaces.

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

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.

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

The objective of this study was to evaluate the survival of PEDV in 9 different feed ingredients when exposed to 60, 70, 80, and 90 °C, as well as the survival on four different surfaces.

The first outbreaks of SVV infection in Brazil were reported in 2014. However, it was not known whether the virus was circulating in Brazilian pig herds before this year.

Porcine Epidemic Diarrhea Virus (PEDV), Porcine Delta Corona Virus (PDCoV), and Transmissible Gastroenteritis Virus (TGEV) are major threats to swine health and contaminated feed plays a role in virus transmission.

The reduction in infectious agents in the air by the EPI technology could potentially decrease the microbial exposure for pigs.

PEDV transmission through contaminated PPE occurs rapidly under modeled conditions. Biosecurity procedures are recommended.

This study showed that oral fluid-based testing could provide an easy and “animal-friendly” approach to sample collection for nucleic acid and/or antibody-based surveillance of PEDV in swine populations.

These studies are the evidences that indirect transmission of PEDV through contaminated personnel, which occurs rapidly, and how fomite material and temperature impact viral stability over time.

The U.S. PEDV prototype and the S-INDEL-variant strains induced similar viremia levels in inoculated pigs.

To our knowledge, this is the first report on the identification, prevalence, complete genome sequencing and molecular characterizations of PDCoV in diarrhoeal samples in pigs in China.

Most commensal bacteria (i.e. Psychrobacter, Prevotella, and Faecalibacterium) in the healthy gastrointestinal tract were decreased due to dysbiosis induced by PEDV infection.
