Descriptive epidemiology of a classical swine fever outbreak in the Limburg Province of Belgium in 1997.
herd in a different area. The mode of virus introduction for this primary infected herd and for the one herd that was not infected by this primary herd could not be determined. Clinical, serological, and ...
p53 expression and apoptosis in melanomas of dogs and cats.
The tissue sections were analysed using a quantitative image analysing system. A p53 index (p53I) and an apoptotic index (AI) were determined. p53 over-expression was found infrequently in these canine ...
DNA ploidy and nuclear morphometric variables for the evaluation of melanocytic tumors in dogs and cats.
Biopsy Cat Diseases Cats Densitometry DNA, Neoplasm Dog Diseases Dogs Melanoma Ploidies Abstract: OBJECTIVE: To determine the prognostic importance of the DNA content and nuclear morphometric variables in ...
Infectious bursal disease (Gumboro disease).
true incidence of different types is difficult to determine. Moreover, the infection, when not fatal, leads to a degree of immunosuppression which is often difficult to measure. Finally, the control ...
Prevalence of bovine herpesvirus-1 in the Belgian cattle population.
Allocation Seroepidemiologic Studies Vaccination Abstract: The national bovine herpesvirus 1 (BHV-1) seroprevalence (apparent prevalence) in the Belgian cattle population was determined by a serological survey ...
Production of antibodies against chicken interferon-gamma: demonstration of neutralizing activity and development of a quantitative ELISA.
Blot analysis or natural ChIFN-gamma in immunofluorescence experiments. As determined by competition ELISA s, mAbs 3D5, 4C6 and 3A3 recognized the same or adjacent epitopes on the ChIFN-gamma molecule, ...
Comparison of biological activities of natural and recombinant chicken interferon-gamma.
replication of cytolytic viruses in chicken embryo fibroblasts and to activate macrophages, as was determined by nitric oxide production. Levels ranging between 100 and 300 microg/ml of BacChIFN-gamma could be ...
Phylogenetic analysis of European encephalomyocarditis viruses: comparison of two genomic regions.
The phylogenetic relationships of encephalomyocarditis (EMC) viruses isolated from pigs and rodents in Europe were determined by comparison of nucleotide sequences from two different regions of the ...
Detection and genotyping of bovine diarrhea virus by reverse transcription-polymerase chain amplification of the 5' untranslated region.
bovine diarrhea virus (BVDV) from other pestiviruses, and to determine the genotype of the BVDV isolates. For this purpose, primer pairs were selected in the 5’ untranslated region (5’ UTR). The primers BE ...
Identification of encephalomyocarditis virus in clinical samples by reverse transcription-PCR followed by genetic typing using sequence analysis.
was clearly shown to be the most suitable organ. The detection limit was determined to be 1 viral particle in 100 mg of heart tissue. The sensitivity and specificity of the assay on the basis of the ...
