Seroprevalence of Borrelia burgdorferi, Anaplasma phagocytophilum, and Francisella tularensis Infections in Belgium: Results of Three Population-Based Samples.
seroprevalence of Ap was estimated at 8.1% for workers professionally exposed, 6.2% for rural blood donors, and 5.7% for urban blood donors. Tularemia sera confirmed the presence of the pathogen in Belgium at 2.0% ...
Towards the development of innovative multi-mycotoxin reference materials as promising metrological tool for emerging and regulated mycotoxin analyses.
initial dry matter) and significant changes in ergosterol contents (≥±10 %) did not occur. Using the mycotoxin contents in wheat flour stored at-80 °C as reference values, statistically significant ...
Detection and Molecular Characterization of Foot and Mouth Disease Viruses from Outbreaks in Some States of Northern Nigeria 2013-2015.
in four states (Kaduna, Kwara, Plateau and Bauchi) in northern Nigeria. FMDV non-structural protein (NSP) seroprevalence for the outbreaks was estimated at 80% (72 of 90) and 70% (131 of 188) ...
Replication-Deficient Particles: New Insights into the Next Generation of Bluetongue Virus Vaccines.
Viral Vaccines Virion Abstract: Bluetongue virus (BTV) is endemic in many parts of the world, often causing severe hemorrhagic disease in livestock. To date, at least 27 different serotypes have been ...
Pre-registration efficacy study of a novel marker vaccine against classical swine fever on maternally derived antibody positive (MDA+) target animals.
vaccinated four weeks before farrowing with CSF virus (CSFV) strain “Thiverval”. A total of 40 piglets with MDA s were included in this study. At six weeks of age the piglets were allocated into three ...
Polyphosphates and Fulvates Enhance Environmental Stability of PO4-Bearing Colloidal Iron Oxyhydroxides.
polyphosphates (poly-P’s) as coatings. The PO4-Fe- NP s are unstable at Ca concentrations above 0.1 mM. Addition of FA and some poly-P’s significantly improved stability. Zeta potential explained colloidal ...
Residues of chlortetracycline, doxycycline and sulfadiazine-trimethoprim in intestinal content and feces of pigs due to cross-contamination of feed.
Drug Residues Feces Food Contamination Gastrointestinal Contents Sulfadiazine Swine Trimethoprim Abstract: BACKGROUND: Cross-contamination of feed with low concentrations of antimicrobials can occur at ...
Chemical analyses of dredged spoil disposal sites at the Belgian part of the North Sea.
Part of the North Sea is evaluated. A linear mixed-effect model was applied to PCB, PAH and heavy metal data from 2005 to 2014. No decrease in PCB concentrations was found, with even an increase at two ...
Experimental bluetongue virus superinfection in calves previously immunized with bluetongue virus serotype 8.
superinfection and at the viraemic peak, there were an average of above 1000 times more BTV15 genomic copies than BTV1 ones. BTV1 RNA could be detected only in the spleen of one calf whereas BTV15 RNA was found in ...
Comparison of PRRSV Nucleic Acid and Antibody Detection in Pen-Based Oral Fluid and Individual Serum Samples in Three Different Age Categories of Post-Weaning Pigs from Endemically Infected Farms.
category, pen-based oral fluid samples were always found PCR positive when at least 30% of the individual pigs were positive in serum. PRRSV specific antibody detection in oral fluid by ELISA showed a 100% ...
