Serodiagnosis of whooping cough in Belgium: results of the National Reference Centre for Bordetella pertussis anno 2013.
2013 by the NRC Bordetella. METHODS: Determine cases of acute infection using an anti-pertussis toxin (PT) IgG antibody ELISA. RESULTS: A total of 2471 serum samples were received. Clinical information ...
Determinants of the Bovine Leukemia Virus Envelope Glycoproteins Involved in Infectivity, Replication and Pathogenesis.
example, immunoreceptor tyrosine-based activation motifs (ITAM) of the envelope transmembrane protein (TM) are essential determinants of infection. Although cell fusion directed by the aminoterminal end of ...
The Monte Carlo validation framework for the discriminant partial least squares model extended with variable selection methods applied to authenticity studies of Viagra® based on chromatographic impurity profiles.
set of samples. In this study, as an illustrative example, 46 authentic Viagra® samples and 97 counterfeit samples were analyzed and described by their impurity profiles that were determined using high ...
A molecular approach for the rapid, selective and sensitive detection of Exophiala jeanselmei in environmental samples: development and performance assessment of a real-time PCR assay
selectivity (100 %), PCR efficiency (95.5 %), dynamic range and repeatability of this qPCR assay were subsequently evaluated. The limit of detection for this qPCR assay was determined to be 1 copy of genomic ...
Pseudorabies virus isolates from domestic pigs and wild boars show no apparent in vitro differences in replication kinetics and sensitivity to interferon-induced antiviral status.
differences in virulence are, however, lacking. Different virulence determinants that can be assessed in vitro were determined for five domestic swine strains, four wild boar strains and the NIA3 reference ...
Determination of halogenated flame retardants in food: optimization and validation of a method based on a two-step clean-up and gas chromatography-mass spectrometry
on a two-step clean-up and gas chromatography-mass spectrometry analysis for the determination of emerging halogenated flame retardants (HFR s), such as dechlorane plus (DP) and brominated phthalates, ...
Quantitative Determination of Migrating compounds from Plastic Baby Bottles by Validated GC-QqQ-MS and LC-QqQ-MS Methods
the majority of the selected compounds. Linearity ranged using Mandel’s fitting test between coefficients of determination (R 2) of 0.995 and 0.999. Both repeatability and reproducibility were ...

Migration of 17 Photoinitiators from Printing Inks and Cardboard into Packaged Food- Results of a Belgian Market Survey
determination of photoinitiators in dry foodstuffs is described: benzophenone (BP), 4,4′‐bis(diethylamino)benzophenone (DEAB), 2‐chloro‐9H‐thioxanthen‐9‐one (CTX), 1‐chloro‐4‐ropoxy‐9H‐thioxanthen‐9‐one (CPTX), ...
Prevalence and Genetic Diversity of Livestock-Associated Methicillin-Resistant Staphylococcus aureus on Belgian Pork.
a high prevalence was observed in pigs. At present, questions remain about the transmission of LA- MRSA to the general human population through pork. The objectives of the present study were to determine ...
