Strain-Level Metagenomic Data Analysis of Enriched In Vitro and In Silico Spiked Food Samples: Paving the Way towards a Culture-Free Foodborne Outbreak Investigation Using STEC as a Case Study.
species, present in a microbial community, which has up until now not been demonstrated for this application. The current work shows the feasibility of strain-level metagenomics of enriched food matrix ...
A Practical Method to Implement Strain-Level Metagenomics-Based Foodborne Outbreak Investigation and Source Tracking in Routine.
outbreak depends on the rapid and accurate identification of the responsible food source. Conventional methods based on isolation of the pathogen from the food matrix and target-specific real-time polymerase ...
PT-2020-NRL-TE-FASFC “Determination of As, Cd, Pb and Hg in food supplements"
be derived for Hg. The measurement of As was difficult, but overall the laboratories performed satisfactory. The performance of the laboratories to analyse Pb, and Cd in this matrix was ...
Detection of toxins involved in foodborne diseases caused by Gram‐positive bacteria
toxicological end points, solubility, and stability, types of food matrix to which they are mostly related to. These differences influence the characteristics of required detection methods. Therefore, detection ...
Lineages Within the Trichophyton rubrum Complex.
185, Issue 1 (2020) Keywords: Arthrodermataceae Phylogeny Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization Trichophyton Abstract: The most important species of the Trichophyton rubrum ...
DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS
time of 12 minutes was developed and optimized for both identification and quantification of the leachables. Matrix effects were corrected by using matrix-matched calibration and methyl cinnamate was ...
Selection of a Noninvasive Source of Human DNA Envisaging Genotyping Assays in Epidemiological Studies: Urine or Saliva?
preferred noninvasive matrix for genotyping purposes in large-scale genetic epidemiologic studies. Only in particular cases using urine could nevertheless be considered useful, although specific limitations ...
Analysis of mineral oil in food: An analytical challenge
matrix has also an important impact, not only on data integration and interpretation but also on the sample preparation. Due to the presence of olefins and natural alkanes, some matrices require auxiliary ...
Species Distinction in the Trichophyton rubrum Complex.
matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI- TOF MS) and amplified fragment length polymorphism (AFLP) were partially consistent with the ITS data but failed to distinguish ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
negative electrospray ionization. Labeled internal standards and matrix-matched calibration are used for quantification of the compounds. The method was validated according FDA guideline for bio analytical ...
