Dietary exposure of Sorbates (E 200 – 202) and Benzoates (E 210 – 213) for the Belgian population
these FA s was estimated. Three matrix-matched analytical methods were developed using ion chromatography coupled with conductivity detection. The methods were validated in-house and applied to 387 ...
BSFM 2023- L. monocytogenes in Plant-Based Foods: insights from of a recent foodborne outbreak linked to vegan alternative to cheese
by L. monocytogenes was traced back to the consumption of almond-milk & cashew alternative to cheese. This report presents the first occurrence of such a matrix in listeriosis outbreaks in Belgium. ...
Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
a proof-of-concept, we explored the use of adaptive sampling using various databases (depletion of the food matrix i.e. potato, enrichment of a selection of foodborne pathogens, enrichment of a database of ...
Whole-Genome Sequencing-Based Screening of MRSA in Patients and Healthcare Workers in Public Hospitals in Benin.
and confirmed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry in Belgium. Whole-genome sequencing (WGS) was used on the confirmed MRSA isolates, to characterize their ...
Spectroscopic approaches for conformity analysis of e-liquids
samples. After obtaining the data matrices, chemometric analysis was performed. For each type of data, the sample matrix was split into a training and test set. Spectroscopic data were preprocessed before ...
Implementation of MALDI-TOF Mass Spectrometry to Identify Fungi From the Indoor Environment as an Added Value to the Classical Morphology-Based Identification Tool
it is necessary to seek for fast and accurate tools, such as Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDITOF MS), enabling an identification to the species level ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
bivalve). These samples were not enriched as it is particularly arduous to culture these viruses in laboratory conditions. Because the contamination level was low in a complex matrix, we tested several sample ...
Identification of Mycobacterium abscessus Subspecies by MALDI-TOF Mass Spectrometry and Machine Learning.
J Clin Microbiol, Volume 61, Issue 1 (2023) Keywords: Humans Mycobacterium Mycobacterium abscessus Mycobacterium Infections, Nontuberculous Nontuberculous Mycobacteria Spectrometry, Mass, Matrix ...
Comparison of 6 DNA extraction methods for isolation of high yield of high molecular weight DNA suitable for shotgun metagenomics Nanopore sequencing to detect bacteriaAbstractBackgroundResultsConclusion
level, were specifically designed for this application and need to be assessed. Results: In this study, with different bacterial cocktail mixes, analyzed as pure or spiked in a synthetic fecal matrix, we ...
Evaluation of a Liquid Media MALDI-TOF MS Protocol for the Identification of Dermatophytes Isolated from Infections.
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI- TOF MS) is gaining new ground for routine identification of filamentous fungi. The main advantages of MALDI- TOF MS are its rapid ...
