The goal of this project was to compare the accuracy of oral-fluids and over-the-shoe booties to the current gold standard of fecal sampling for identification of Salmonella in pigs.

The systematic monitoring of production indicators using EWMA offers opportunity to early detect outbreaks and/or to quantify the production losses attributed to PRRS infection.

The results of the present study demonstrated that the P. multocida isolated from diseased pigs in Taiwan was resistant to multiple antimicrobials.

The results of this study provide clinical information on how to reduce seminal shedding of type 1 PRRSV in boars using type 1 PRRSV-modified live vaccine.

This study highlights the importance of identifying coronavirus diversity and distribution in bats.

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

This study aims to develop a cost-effective, non infectious CSF subunit vaccine that can elicit rapid and long lasting immunity.

This study reports on the first identification of Porcine circovirus type 3 in Europe, in serum from pigs from Polish farms.

Surgical castration has a negative impact on production in the suckling period, especially in pigs in the three lower quartiles for body weight.

According to the initial report from Scandinavia, B. suanatina can be isolated from birds and cross-species infection could be demonstrated infecting pigs with an avian isolate.

The study identifies the ASF transmission rate value in affected natural wild populations, for the first time, which could provide basis for modelling ASF transmission.

The effects of infection by E. coli were dependent of both bacterial load and storage period, whereas the effects of C. perfringens were mainly dependent on the bacterial load.

The objective of this study was to determine the dissemination of multidrug methicillin-resistant Staphylococcus sciuri (MDR-MRSS) in the environment after land application of manure on commercial swine farms.

Unlike domestic swine, feral swine are free ranging and have many opportunities for IAV exposure through contacts with various habitats and animals, including migratory waterfowl, a natural reservoir for IAVs.

In the field, the combined ELISA detected infection in the face of colostral IgG. In growing pigs, the IgM-IgA ELISA is a promising tool for PRRSV surveillance.

This study set out to describe detection patterns of porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), swine influenza virus type A (SIV) and Mycoplasma hyopneumoniae (M. hyo) among farms showing differing severity of PRDC.

In this study, CD163-positive fetuses were completely protected from PRRSV in dams possessing a complete knockout of the CD163 receptor.

Gestation and lactation dietary supplementation mannan oligosaccharide may improve sow and litter performance and immune response.

We identified from suckling piglets with diarrhea in China a new bat-HKU2–like porcine coronavirus (porcine enteric alphacoronavirus). The GDS04 strain of this coronavirus shares high aa identities (>90%) with the reported bat-HKU2 strains in Coronaviridae-wide conserved domains, suggesting that the GDS04 strain belongs to the same species as HKU2.

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.

This study aimed to provide information regarding viral pathogenesis and molecular epidemiology linked with recently reported atypical porcine pestivirus (APPV) strains and to determine the circulation of APPV in Spain from 1997 to 2016.

Salmonella 4,[5],12:i:-, a worldwide emerging pathogen that causes many foodborne outbreaks mostly attributed to pig and pig products, is expanding in the U.S.

The results will help in the design and implementation of early detection, prevention, and control strategies for one of the most devastating diseases affecting the swine industry in the U.S.

In late 2015, an avian-origin H4N6 influenza A virus was isolated from pigs in the United States.
