Validation of two real-time RT-PCR methods for foot-and-mouth disease diagnosis: RNA-extraction, matrix effect, uncertainty of measurement and precision.
decrease was observed for spleen samples. By testing the same dilution series in duplicate on 10 different occasions, an estimation of uncertainty of measurement and precision was obtained using blood as ...
Comparative studies on the pathogenicity and tissue distribution of three virulence variants of classical swine fever virus, two field isolates and one vaccine strain, with special regard to immunohistochemical investigations.

Bluetongue virus serotype 8-associated congenital hydranencephaly in calves.
using a BTV-specific real-time RT- PCR with a much higher success rate in brain tissues compared with blood and spleen samples. Virus isolation in embryonated eggs was unsuccessful. In conclusion, ...
Validation of two commercial real-time RT-PCR kits for rapid and specific diagnosis of classical swine fever virus.
spleen samples collected from the CSF surveillance of wild boars in an area known to be infected and from domestic pigs at a slaughterhouse, confirmed the high sensitivity and specificity of the two kits. ...
