Investigation into the Role of Potentially Contaminated Feed as a Source of the First‐Detected Outbreaks of Porcine Epidemic Diarrhea in Canada
TLDR
Cont contaminated feed cannot be ruled out as a likely source of this introduction of PEDV into Canada in the field where many other variables may play a contributing role.

Further studies to quantify the dose of natural aerosols of foot-and-mouth disease virus for pigs
TLDR
The present experiment confirms the previous findings that pigs, compared to cattle and sheep, are relatively resistant to infection with airborne FMDV.

Appearance of acute PRRS-like symptoms in sow herds after vaccination with a modified live PRRS vaccine
found in the dorsal root ganglia, the ventral horns of the spinal cord or the affected brainstem nuclei. As with other primary dysautonomias, the cause of the dysautonomia in the presented case was…

Foot-and-mouth disease: host range and pathogenesis.
TLDR
The routes and sites of infection, incubation periods and clinical and pathological findings are described and highlighted in relation to progress in understanding the pathogenesis of FMD.

Reassortant Highly Pathogenic Influenza A H5N2 Virus Containing Gene Segments Related to Eurasian H5N8 in British Columbia, Canada, 2014
TLDR
The fact that the British Columbia outbreaks also occurred at a time associated with increased migratory waterfowl activity along with reports by the USA of a wholly Eurasian H5N8 virus detected in wild birds in Washington State, strongly suggest that migratoryWaterfowl were responsible for bringing Eurasia H 5N8 to North America where it subsequently reassorted with indigenous viruses.

Natural aerosol transmission of foot-and-mouth disease virus to pigs: minimal infectious dose for strain O1 Lausanne
TLDR
Under experimental conditions, forty pigs were exposed individually to naturally generated aerosols of FMDV, strain O1 Lausanne, and results indicated that doses under 100 TCID50 failed to infect pigs but doses of approximately 300TCID50 caused short-term sub-clinical infection.
