Equivalent results were observed in 4 independent studies and demonstrate the feasibility of oral fluids and mRT-qPCR for surveillance of ASF, CSF, and FMD in swine populations.

It is proposed that Enterococcus faecium NCIMB 10415 exerts an immune modulatory effect by increasing the numbers of intraepithelial lymphocytes.

This study confirms that Lena strain is highly virulent compared to Finistere strain. With non‐SPF animals coming from commercial herds, we can even expect more severe symptoms because co‐infections are likely.

Results from our study indicate for the first time, that PEDV can be found in the air and that suspended airborne particles can be infectious.

It seems that the currently used cotton ropes are an appropriate choice for sample collection in PRRSV monitoring.

Antimicrobial susceptibility to human-use antibiotics was determined among Belgian faecal Salmonella isolates from healthy pigs and broiler chickens.

The objective of this study was to compare the rhinitis lesions scored on the snouts of pigs according to vaccine status and parity of their mother (primiparous and multiparous; vaccinated or unvaccinated).

PCV2b was the predominant genotype in Croatia and has been linked to international trade as a route of introduction.

The results of this study will provide information about the impacts of disease control protocols which may be useful in choosing the optimal control methods to meet the goals of rapid effective control and eradication.

A naturally attenuated form of PEDv provided significant passive immune protection for seven months against piglet challenge with virulent PEDv.

During 2008–2012, a total of 90 cases of trichinellosis were reported to CDC from 24 states and the District of Columbia.

Information on the conserved antigenicity among PEDV strains is important for the development of PEDV vaccines to protect swine from current highly virulent PEDV infections.

We did not obtain any mutants of Staphylococcus aureus or Mycobacterium tuberculosis resistant to teixobactin.

Porcine reproductive and respiratory syndrome virus was detected mainly in monocytes-macrophages.

PEDV was not infectious on cell culture within 7 days when stored at room temperature and within 21 days when stored at refrigerated temperature.

This study demonstrates the successful transfer of meloxicam from sows to piglets through milk and corresponding analgesia.

Under the conditions of this study, fecal shedding of TTSuV is independent of PoRVA infection in diarrheic piglets aged 1 to 3 weeks.

Even in the absence of clinical signs, growth rate and feed intake are likely to be reduced by L. intracellularis infections. There is a trend that also PCV2 infections can exert a similar negative influence.

A survey of national animal influenza surveillance programmes was conducted to assess the current capacity to detect influenza viruses with zoonotic potential in animals.

Comparing different vaccination strategies against M. hyopneumoniae indicates varying levels of protection. M. hyopneumoniae is still a major problem despite the widely applied vaccination.

Serological data that were obtained by testing meat juice samples from various pig herds were analyzed as proof of the "meat juice multi-serology" concept.

Farms that use living animals for the exposure to gilts during the acclimatization and farms that had increased number of weaned piglets per sow and year were less likely to test positive for M. hyopneumoniae and less likely to develop clinical symptoms of EP in fattening pigs.

From 2011 to 2013, the French network for the surveillance of influenza viruses in pigs (Résavip) has made it possible to conduct 629 visits in 476 farms.

Altogether, these results indicate that modifying feeding practices could help to prepare animals to overcome an influenza infection.
