Bluetongue virus RNA detection by real-time rt-PCR in post-vaccination samples from cattle.
not investigated. To enlighten this point, a large study was performed to determine the risks of detection of bluetongue vaccine-associated RNA in the blood and spleen of cattle using real-time RT- PCR. ...
Diversity of antimicrobial resistance and virulence genes in methicillin-resistant non-Staphylococcus aureus staphylococci from veal calves.
staphylococcus Virulence Factors Abstract: In this study we determined whether methicillin-resistant non-Staphylococcus aureus (MRNAS) from veal calves may be a potential reservoir of antimicrobial-resistance and ...
Pre-registration efficacy study of a novel marker vaccine against classical swine fever on Maternally Derived Antibody negative (MDA-) target animals.
The level of protection was determined by the development of clinical signs, viraemia and rate of mortality. The vaccine candidate met the criteria of Ph. Eur Monograph 0065, “Swine-fever vaccine (live, ...
Measuring general animal health status: Development of an animal health barometer.
including scientists, policy makers and agro-industrial representatives — to determine their relative weight in the barometer. The result of the barometer is expressed as a comparison with a previous year. ...
Antimicrobial resistance and population structure of Staphylococcus epidermidis recovered from pig farms in Belgium.
Abstract: Pigs are known to harbour a variety of staphylococcal bacteria, including Staphylococcus epidermidis, in the upper respiratory tract. The aim of the present study was to determine the prevalence, ...
Co-occurrence of free-living protozoa and foodborne pathogens on dishcloths: implications for food safety.
use was identified as a prime determinant of FLP concentrations on used dishcloths. Bacterial load on dishcloths was high, with a mean total of aerobic bacteria of 7.47 log 10 cfu/cm(2). Escherichia ...
Virulence comparison and quantification of horizontal bovine viral diarrhoea virus transmission following experimental infection in calves.
infections were performed to determine basic reproduction ratios (R0). In each experiment three calves were infected via intranasal inoculation and housed together with seven susceptible animals. Two strains ...
Autochthonous tick-borne encephalitis virus-seropositive cattle in Belgium: a risk-based targeted serological survey.
infected foci in Belgium. Further surveillance in cattle, other sentinels, ticks, and humans at risk is recommended to further determine the location and size of endemic foci and the risk for public health. ...
The combination of attenuated Newcastle disease (ND) vaccine with rHVT-ND vaccine at 1 day old is more protective against ND virus challenge than when combined with inactivated ND vaccine.
of age. We determined that immunity induced by the vaccination programme involving the rHVT- ND vaccine was more protective than that provided by the conventional vaccine-based regime. This might be ...
Genotoxicity evaluation of nanosized titanium dioxide, synthetic amorphous silica and multi-walled carbon nanotubes in human lymphocytes.
hydrodynamic particle size-distributions were determined by dynamic light scattering. Using a standardized procedure to ensure the dispersion of the NM s and the cytokinesis-block micronucleus assay (without ...
