Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
samples during an outbreak investigation requires the samples to be enriched in order to reach detectable levels. However, a bias can occur during the enrichment of the food due to competition between the ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
have always been analyzed and characterized after isolation. Since the advent of second generation sequencing, it has been possible to characterize the complete genome of these isolates to the SNP level ...
Shotgun metagenomics as a ONE Health tool for better protecting human health
laboratories, however without isolation and in a shorter time-frame. This could be achieved to the strain level even in samples with several E. coli strains. The method was also used to solve a Salmonella ...

An Alternative Method Validation Strategy for the European Decision 2002/657/EC
ISO 11843 standards are used to set up an experimental validation plan that minimizes the number of samples without increasing the uncertainty of the performance characteristics. At each level (0.5, ...
Food contamination with pyrrolizidine alkaloids: the expected and the unexpected
food items. The Belgian Scientific Institute of Public Health (WIV- ISP) has directed a project aiming to report occurrence levels of PA s and PANO s in targeted food items to perform a dietary exposure ...
