Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
electron microscopy (TEM) was used as a confirmatory technique and served as the basis for bias estimation. The optimisation of the sample preparation step showed that when this protocol was applied to the ...
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 ...
Genetic elements associated with antimicrobial resistance among avian pathogenic Escherichia coli.
TEM), chloramphenicol (cat1), kanamycin (aphA1), and sulphonamide (sul1 and sul2). Among ciprofloxacin-resistant isolates, the S83L mutation was the most frequently substitution observed in the quinolone ...
Development of a Luminex xTAG® assay for cost-effective multiplex detection of β-lactamases in Gram-negative bacteria.
non- ESBL SHV- and TEM-likes, OXA-½/7-likes, PER, VEB, GES), plasmid-mediated cephalosporinases (CMY, MOX, FOX, ACC, DHA, MIR / ACT) and carbapenemases (OXA-48, NDM, KPC, VIM, IMP). METHODS: A modular ...
Clonal emergence of extended-spectrum beta-lactamase (CTX-M-2)-producing Salmonella enterica serovar Virchow isolates with reduced susceptibilities to ciprofloxacin among poultry and humans in Belgium and France (2000 to 2003).
beta-lactamase, CTX-M-2, concomitantly with a TEM-1 beta-lactamase. The bla(CTX-M-2) gene was located on a large conjugative plasmid (>100 kb). Pulsed-field gel electrophoresis indicated a clonal relationship ...
