In conclusion, combined vaccination against both Mhp and PRRSV efficiently pooled the efficacy of each single PRRSV and Mhp vaccination and could be an interesting tool to control PRDC in European swine production.

Our data indicated that H3N8 IAV from wild aquatic birds have the potential to cross the species barrier and establish successful infections in pigs that might spread unnoticed using HAI as diagnostic tool.

Under Belgian and Dutch field conditions, piglets may be infected with M. hyo very early in life, with prevalence increasing further during the post-weaning period.

The results from this herd indicated that PCV2 vaccination may reduce the PCV2 infection level even during an acute outbreak of PRRS, but the results also showed that PCV2 vaccination does not eradicate the virus from the herd. Further studies are needed to draw general conclusions on this matter.

Overall, our findings indicate that at least 12 genetically distinct HA lineages circulate in Latin American swine herds, only two of which have been found in North American swine herds.

Results indicated that airborne PEDV, IAV and PRRSV can be found in a wide range of particle sizes. However, virus viability is particle size dependent.

Our results suggest that infection with IAV or PRRSV in the pre-weaning period is associated with an increase in post-weaning mortality.

This study demonstrated for the first time that TTSuV viremia can be controlled by a combined DNA and protein immunization.

The aim of this work was to evaluate whether acute phase protein (APP) determinations could assist Official Veterinarians carrying out work in slaughterhouses.

This study indicates that serological screening for A. suum on fattening farms is an attractive new diagnostic tool that can be used to indicate the presence of roundworm infection by measuring infection intensity.

Under the conditions of this study, PEDV viability in feed was influenced by ingredient with extended survival in SBM. Furthermore, LA treatment rendered virus inactive, independent of ingredient type.

Based on these findings, we recommend that IAV control strategies be aimed at preventing infection before gilts are introduced into the farm, and in pigs prior to weaning.

The main aim of this study was to quantify the amount of virus shed in feces of pigs vaccinated with attenuated or inactivated vaccines and in unvaccinated pigs following challenge with Lelystad PRRS virus strain.

Here we report the isolation and characterization of a novel mammalian orthoreovirus 3 (MRV3) from diarrheic feces of piglets from these outbreaks in three states and ring-dried swine blood meal from multiple sources.

This study highlights the importance of continued monitoring of PRRSV evolution using genomic sequencing.

The macrolide tylvalosin and the pleuromutilin valnemulin exhibited the highest in vitro antimicrobial activities against M. hyopneumoniae field isolates in comparison with the other tested antibiotics.
