Diagnosis, prevention and control of urinary tract infections: a survey of routine practices in Belgian nursing homes

Dipstick tests and urine cultures were routinely performed in 30.2% and 44.6% of the facilities, respectively. In non-catheterised residents, voided or midstream urine sampling was most frequently applied. ...

Influence of reduced levels or suppression of sodium nitrite on the outgrowth and toxinogenesis of psychrotrophic Clostridium botulinum Group II type B in cooked ham.

portioned and samples of 50 g were vacuum packed then cooked and cooled based on thermal processing employed by the meat processing industry. These cooked ham model samples were stored under reasonably ...

Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.

products by transmission electron microscopy (TEM) and single-particle inductively coupled plasma-mass spectrometry (spICP- MS). TEM analysis showed that all samples contained micrometre-sized flakes and ...

Chemical and toxciological characterization of e-liquid cigarettes

the revised TPD. The samples were examined for the presence of nicotine, nicotine-related impurities, volatile organic compounds, caffeine, taurine and the harmful flavours diacetyl and acetylpropionyl. ...

A Practical Method to Implement Strain-Level Metagenomics-Based Foodborne Outbreak Investigation and Source Tracking in Routine.

in food samples containing different strains, including a combination of different STEC strains. For the first time, we also managed to link individual strains from a food product to isolates from ...

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 ...

The Benefits of Whole Genome Sequencing for Foodborne Outbreak Investigation from the Perspective of a National Reference Laboratory in a Smaller Country.

National Reference Laboratories of smaller countries often show slower uptake of WGS, mainly because of significant investments required to generate and analyze data of a limited amount of samples. To ...

Food Chemistry, Function and AnalysisDNA Techniques to Verify Food Authenticity CHAPTER 8. GMO Detection and Identification Using Next-generation Sequencing

feasibility in supporting the current genetically modified organism (GMO) routine detection systems for unauthorized GMO. Depending upon the specific samples under investigation, two categories of NGS ...

Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.

standardized and validated methodologies to characterize representative samples of 15 pristine E171 materials based on transmission electron microscopy (TEM) and single-particle inductively coupled plasma mass ...
