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.

Homologous re-challenge 49 days post initial PEDV exposure did not result in re-infection of the pigs. This demonstrates potential for an effective PEDV vaccine.

These baseline results suggest that oral-fluid samples can be collected from individually housed sows, but that further studies on the optimization of oral-fluid collection in the sow unit (gestation and farrowing) would be of value.

Although the infection of the C. novyi type B is uncommon, these results can be a useful data for further investigation of C. novyi type B because there was few survey detecting the infection of C. novyi type B for now.

The results demonstrate that the PRRSV-CON virus can serve as a potential vaccine candidate for the development of a novel PRRS vaccine with broader cross-protection.

We speculate that co-infection with PCV2 and HEV may bring some negative effect on pig production and recommend that more attention should be paid to this phenomenon.

Results demonstrate that IRT can help to detect inflammatory lung alterations in the pig lung.

This paper describes the first application of LCM to study the cytokine transcript profiles and virus distribution in different compartments of the lymph node of pigs.

Holding PEDV in the presence of feces at 71°C for 10 minutes or at 20°C (room temperature) for 7 days is sufficient to inactivate the virus, preventing transmission under the conditions of this study.

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.
