Comparing responses to different selenium sources and dosages in laying hens.
effect of Se source or dosage was observed on serum GP x levels. Selenium in eggs was significantly affected by dosage and source of Se. The Se supplementation level in the feed was reflected in the eggs, ...
Virulence comparison and quantification of horizontal bovine viral diarrhoea virus transmission following experimental infection in calves.
spread. Additionally, the severe clinical symptoms observed in the field with these isolates could not be reproduced during these experiments, suggesting that other factors besides strain virulence ...
Phage and MLVA typing of Salmonella enteritidis isolated from layers and humans in Belgium from 2000-2010, a period in which vaccination of laying hens was introduced.
in layers and humans before 2007, a significant reduction of those PT s was observed in both populations in the period 2007-2010. The relative proportion of PT4 b, PT21 c and PT6 c was found to have ...
Dose-dependent effect of experimental Schmallenberg virus infection in sheep.
of three ewes were each inoculated subcutaneously with 1 mL of successive 10-fold dilutions of an SBV infectious serum. The ewes were monitored for 10 days, but no clinical signs were observed. The ...
Molecular characterization of Belgian pseudorabies virus isolates from domestic swine and wild boar.
analysis, Belgian wild boar isolates belonging to both clade A and B were observed, while all domestic swine isolates clustered within clade A. The joint phylogenetic analysis of both wild boar and domestic ...
False-positive results in metagenomic virus discovery: a strong case for follow-up diagnosis.
parvovirus-like nucleic acids or virus particles. Although we did not find any relevant virus that could be associated with the disease, these observations clearly illustrate the importance of using a proper ...
Vaccination of mice using the West Nile virus E-protein in a DNA prime-protein boost strategy stimulates cell-mediated immunity and protects mice against a lethal challenge.
E-specific IL-4 T-cell immune responses were detected by ELISPOT after protein boost and CD8 (+) specific IFN-γ expression was observed by flow cytometry. Challenge experiments using the heterologous ...
Experimental Schmallenberg virus infection of pigs.
spleen) were sampled. No clinical impact was observed and all collected samples tested negative for SBV in rRT- PCR. Despite the absence of viremia and virus transmission, low and short lasting amounts of ...
Distinction between persistent and transient infection in a bovine viral diarrhoea (BVD) control programme: appropriate interpretation of real-time RT-PCR and antigen-ELISA test results.
sampling. A highly significant difference in cycle threshold (Ct) values obtained by RT- PCR was observed between PI and TI animals. ROC analysis was performed to establish thresholds to confirm with high ...
Towards a typing strategy for Arcobacter species isolated from humans and animals and assessment of the in vitro genomic stability.
assessed under two temperatures and two oxygen concentrations. Variability in the genomic profile of A. cryaerophilus was observed after different passages for different strains at 37°C under microaerobic ...
