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

their variants, 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 ...

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 ...

In vitro toxicity, genotoxicity and antigenotoxicity of Nigella sativa extracts from different geographic locations

include alkaloids, flavonoids, and terpenoids. Therefore their properties and biological effects may be different. We used the neutral red uptake test, the bacterial Vitotox and Ames assays and the ...

Dietary supplementation of tannin-extracts to lambs: effects on meat fatty acids composition and stability and on microbial characteristics.

material rich in hydrolysable (Tara, T;  Caesalpinia spinosa) or condensed (Mimosa, M;  Acacia mearnsii) tannins were added to lamb’s diet and their effects on meat quality and on microbial population were ...

Opinion: Airtightness for Decontamination by Fumigation of High-Containment Laboratories

by fumigation. Methods: Biological indicators (BI s) consisting of spores of Geobacillus stearothermophilus on metal disks were laid out in laboratories of different levels of airtightness before performing ...

An international outbreak of Salmonella enterica serotype Enteritidis linked to eggs from Poland: a microbiological and epidemiological study.

chain, although changes in strain population dynamics and fewer cases indicate that control measures had some effect. Routine use of WGS in salmonella surveillance and outbreak response promises to ...

Transcriptional profiling of a laboratory and clinical Mycobacterium tuberculosis strain suggests respiratory poisoning upon exposure to delamanid

found with components that affect aerobic respiration. This demonstrates that, besides the inhibition of cell wall synthesis, respiratory poisoning plays a fundamental role in the bactericidal effect of ...

Comparison of SNP-based subtyping workflows for bacterial isolates using WGS data, applied to Salmonella enterica serotype Typhimurium and serotype 1,4,[5],12:i:.

PLoS One, Volume 13, Issue 2 (2018) Keywords: bacterial phylogeny; food-borne; genes; NGS; WGS; computational biology/bioinformatics; disease outbreaks; outbreak; performance evaluation; pipeline; ...

Monitoring of Laboratory-Acquired Infections

the inherent safe nature of GMO s (“biological containment”), whether or not in combination with adherence to effective safety measures. Most of the reported LAI s are infections with wild-type, ...
