Antimicrobial resistance continues to be a growing threat globally, specifically in health-care settings in which antimicrobial-resistant pathogens cause a substantial proportion of health-care-associated infections (HAIs). Next-generation sequencing (NGS) and the analysis of the data produced therein (ie, bioinformatics) represent an opportunity to enhance our capacity to address these threats. The 3rd Geneva Infection Prevention and Control Think Tank brought together experts to identify gaps, propose solutions, and set priorities for the use of NGS for HAIs and antimicrobial-resistant pathogens.

The nickel-pincer nucleotide (NPN) is an organometallic cofactor that was first discovered in lactate racemase from . In this review, we provide an overview on the structure-function relationships of enzymes that utilize or are involved in the biosynthesis of the NPN cofactor. Recent structural advances have greatly extended our understanding of the biological role of the NPN cofactor in a diverse family of 2-hydroxyacid racemases and epimerases.

The abnormally viscous and thick mucus is a hallmark of cystic fibrosis (CF). How the mutated CF gene causes abnormal mucus remains an unanswered question of paramount interest. Mucus is produced by the hydration of gel-forming mucin macromolecules that are stored in intracellular granules prior to release.

Microorganisms are present in snow/ice of the Antarctic Plateau, but their biogeography and metabolic state under extreme local conditions are poorly understood. Here, we show the diversity and distribution of microorganisms in air (1.5 m height) and snow/ice down to 4 m depth at three distant latitudes along a 2578 km transect on the East Antarctic Plateau on board an environmentally friendly, mobile platform.
