TL;DR: In this article, the authors report mutagenesis, functional, and structural data to confirm that this locus, and Cj1324 in particular, has a significant contributory role in the colonization of chickens by C. jejuni.

TL;DR: A focused metabolomics approach to define the function of flagellin glycosylation genes in Campylobacter jejuni and demonstrate the usefulness of this approach for targeting compounds within the bacterial metabolome to assign function to genes, identify metabolic intermediates, and elucidate novel biosynthetic pathways.

TL;DR: It is demonstrated that, in addition to CMP-pseudaminic acid, C. coli VC167 also produces two structurally distinct nucleotide-activated nonulosonate sugars that were observed as negative ions at m/z 637 and m/Z 651 (CMP-315 and CMP -329).

TL;DR: A comparison of the SPME/LC/MS method with LC/MS methods utilizing traditional sample preparation techniques, shows that the former offers similar performance in terms of precision, linearity and detection limits, but is clearly easier to use and faster to perform.

TL;DR: The use of a benchtop Orbitrap system for liquid chromatography–mass spectrometry (LC-MS) screening of multiple classes of biotoxins commonly found in shellfish yielded mass accuracy of less than 1 ppm error at a resolving power of 100,000 for the analytes studied.
