Molecular typing of Aspergillus terreus isolates by random amplification of polymorphic DNA36693

with two different primers NS3 and NS7 from the fungal ribosomal 18S subunit gene. For the 31 epidemiologically unrelated isolates tested, the primers NS3 and NS7 gave rise to 23 and 24 different ...

Classical swine fever virus: a ring test to evaluate RT-PCR detection methods.

and Specificity Abstract: Six laboratories participated in an exercise to compare the sensitivity and specificity of RT- PCR tests for the detection of classical swine fever virus (CSFV). Two sets of ...

What is the optimal regimen for BCG intravesical therapy? Are six weekly instillations necessary?

 instillations. MATERIALS AND METHODS: The evolution of the lymphoproliferative response of peripheral blood mononuclear cells against BCG culture filtrate (CF), tuberculin (PPD) and BCG extract (EXT) was tested ...

Cloning of the gene encoding a 22-kilodalton cell surface antigen of Mycobacterium bovis BCG and analysis of its potential for DNA vaccination against tuberculosis.

measured by interleukin-2 and gamma interferon secretion, was only modest, and no protection against intravenous M. tuberculosis challenge was observed in any of the three mouse strains tested. Therefore, ...

Prevalence of herds with young sows seropositive to pseudorabies (Aujeszky's disease) in northern Belgium.

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 ...
