A genoserotyping system for a fast and objective identification of Salmonella serotypes commonly isolated from poultry and pork food sectors in Belgium.

subjected to an official control in the Belgian food sector. In this study, 3 additional assays using the same technology were developed for the rapid and cost-effective detection of 13 dangerous highly ...

Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.

products, respectively. Similar size distributions were obtained by spICP- MS and TEM, considering the limit of detection of spICP- MS. The median of the equivalent spherical diameter of the fraction of ...

Chemical and toxciological characterization of e-liquid cigarettes

e-liquid refills. First, a comprehensive literature search was performed to obtain an overview about the chemical composition of the e-liquids and the analytical methods used for their detection. Although the ...

QuilA-Adjuvanted T. gondii Lysate Antigens Trigger Robust Antibody and IFNγ+ T Cell Responses in Pigs Leading to Reduction in Parasite DNA in Tissues Upon Challenge InfectionImage

vaccine induced the strongest immune response and reduced the parasite DNA load below the detection limit in brain and skeletal muscle tissue in most animals. These findings might inform the development of ...

Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.

December 2019. COVID-19 cases are confirmed by the detection of SARS-CoV-2 RNA in biological samples by RT-qPCR. However, limited numbers of SARS-CoV-2 genomes were available when the first RT-qPCR methods ...

The African swine fever virus isolate Belgium 2018/1 shows high virulence in European wild boar.

viral genome were also detected in genitals and accessory sex glands of two boars. There were no antibodies detectable in commercial antibody ELISA s, antibody LFD s and indirect immunoperoxidase tests. ...

DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS

irritating com-pounds, with concentrations of up to 30 μg/g being detected after 8 hours of exposure: -isomethyl ionone, benzyl salicylate, hexyl cinnamaldehyde, linalool and piperonal. For every compound, ...

A new multiplex RT-qPCR method for the simultaneous detection and discrimination of Zika and chikungunya viruses

outbreak, early diagnosis, and therefore fast and adequate detection, is needed. To this end, a multiplex reverse transcription real-time polymerase chain reaction TaqMan method was designed to detect Zika ...

Strategy for the identification of micro-organisms producing food and feed products: Bacteria producing food enzymes as study case

products. Currently, no strategy targeting such impurities exists in enforcement laboratories. Therefore, a generic strategy of first line screening was developed to detect and identify, through PCR ...
