Chain‐Length Regulation by WzzE Is Necessary for, but Genetically Separable From, Cyclic Enterobacterial Common Antigen Synthesis

Molecular Microbiology, EarlyView.
Here, we demonstrate that polysaccharide chain length regulation plays a distinct role in enabling formation of a cyclic molecule important for the bacterial cell surface. However, this function is necessary, but not sufficient for the cyclic molecule's biosynthesis.

A Single‐Nucleotide Substitution Generates a de Novo Promoter That Activates a Latent Metabolic Bypass in Escherichia coli

Molecular Microbiology, EarlyView.
A chromosomal mutation allows bypass of deletion of the Escherichia coli fabH gene. The bypass results from creation of a new promoter that drives increased madA transcription, resulting in increased synthesis of acetyl‐acyl carrier protein by decarboxylation of malonyl‐acyl carrier protein.

The Synergy Between a Silver‐Ruthenium Antimicrobial and Aminoglycosides Is Based on Severe Macromolecular Damage

Molecular Microbiology, EarlyView.
AGXX enhances aminoglycoside activity against multidrug‐resistant pathogens such as uropathogenic Escherichia coli by increasing reactive oxygen species, causing protein aggregation and DNA damage. This effect is reduced by oxygen limitation or antioxidants. Polyphosphate protects cells from oxidative damage.

A multiplex assay to detect mosquito species, bloodmeal host source and Plasmodium in malaria vectors using Nanopore amplicon sequencing

Medical and Veterinary Entomology, EarlyView.
Insectary‐reared mosquitoes were simultaneously assessed for species identification, bloodmeal source analysis and Plasmodium detection, using a single multiplexed sequencing run on the MinION sequencing platform. The method was applied to 150 insectary‐reared mosquitoes, representing nine species blood‐fed with five vertebrate hosts and 40 samples for

Impact of delayed blood donation sample processing and testing on SARS‐CoV‐2 serological assay results in an evolving pandemic response

Transfusion, EarlyView.
Abstract Background The two largest US blood collection organizations led a multiphased, multicenter nationwide SARS‐CoV‐2 blood donor‐based serosurveillance program. The potential impact of delayed sample processing and prolonged refrigerated or frozen storage on anti‐SARS‐CoV‐2 antibody detection was investigated.
