Metagenomics-based tracing of genetically modified microorganism contaminations in commercial fermentation products
* Source: Food Chemistry: Molecular Sciences, Volume 10 (2025) Keywords: Antimicrobial resistance food enzyme phylogenomics Strain-level deconvolution Abstract: Genetically modified microorganisms (GMM) are ...
Protective efficacy of classical vaccines and vaccination protocols against an exotic Newcastle disease virus genotype VII.2 in Belgian layer and broiler chickens.
this velogenic APMV-1 VII.2 strain. For fully field-vaccinated 26-week-old layer chickens, high levels of specific antibodies were measured at the time of the velogenic APMV-1 challenge, resulting in ...
FT-IR spectroscopy as a rapid method for Salmonella spp. typing
subspecies level a, which is crucial for the early management of foodborne outbreaks. However, implementing it in a routine laboratory requires the development of a standardized protocol due to the high ...
Assessment of receptor-mediated activity (AhR and ERα), mutagenicity, and teratogenicity of metal shredder wastes in Wallonia, Belgium.
the bacterial reverse gene mutation test using the Salmonella typhimurium TA98 and TA100 strains. Except for the sludge sample (site 3), all samples induced a mutagenic response in the TA98 strain (± ...
Antimicrobial resistance in ESBL and indicator E. coli, Campylobacter spp.,Salmonella spp., methicillin-resistant Staphylococcus aureus (MRSA) and Enterococcus faecalis and faecium isolated from food and food-producing animals (primary production) in 2023
βlactamases/AmpC/carbapenemase producing E. coli is done on strains isolated from food-producing animals and meat derived thereof. Microbiological resistance was assessed using epidemiological cutoff values (ECOFF) according to ...
Validation of a Targeted LC-MS/MS Method for Cereulide and Application in Food and Faeces.
is an emetic toxin produced by some strains of. This bacterial toxin, a cyclic 1.2 kDa dodecadepsipeptide, is stable to heat and acids and causes nausea and vomiting when ingested via contaminated ...
Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
adaptive sampling, following whole genome amplification to increase the amount of genetic material to meet sequencing standards. The strain-level data analysis was performed as previously described (Buytaers ...
Microbial quality analysis of falsified medicines seized by controling agencies
refers to the amount and type of microorganisms present in a sample and reflects the level of biological contamination and associated potential health risks upon consumption of the product. We initially ...
Time series modelling for wastewater-based epidemiology of COVID-19: A nationwide study in 40 wastewater treatment plants of Belgium, February 2021 to June 2022
pepper mild mottle virus (PMM oV) concentration, a measure of human faeces in wastewater, and variants (alpha, delta, and omicron strains) on SARS-CoV-2 RNA levels in wastewater. Secondly, adjusted WBE ...
A global genomic analysis of Salmonella Concord reveals lineages with high antimicrobial resistance in Ethiopia.
super-lineages. Super-lineage A is composed of eight S. Concord lineages, of which four are associated with multiple countries and low levels of AMR. Other lineages are restricted to Ethiopia and horizontally ...
