in West Flanders (68%), followed by Antwerp (60%), East Flanders (43%), Limburg (18%), and Flemish Brabant (8%). Assuming a diagnostic test sensitivity and specificity of 95% and 99%, respectively, and ...
Highly sensitive detection of swine vesicular disease virus based on a single tube RT-PCR system and DIG-ELISA detection.
concentrated using an ultrafiltration system and RNA extracted with the Purescript kit. The specificity of the test was validated on 27 SVDV strains belonging to four different groups. No cross-reactivity with ...
Detection and genotyping of bovine diarrhea virus by reverse transcription-polymerase chain amplification of the 5' untranslated region.
amplification product of the expected size was obtained with either the B3B4 or the B5B6 primer pairs for the 107 BVDV isolates tested but not for BDV or CSFV. For some isolates that were grouped in the genotype ...
