This study shows that reduced swimming motility accompanies B-lactam antibiotic resistance in E. coli through efflux mechanisms, with motility recovery after antibiotic removal.

This study evaluates seven DTC gut microbiome testing services using standardized fecal material, revealing significant variability in analytical performance comparable to biological donor differences.

This paper develops and demonstrates modified quality metrics for microbial cell counting methods to improve accuracy and comparability across different techniques.

This paper introduces a mathematical framework using internal standards to correct compositional biases in microbiome datasets, improving accuracy and precision in taxa abundance measurements.

The paper evaluates metagenomic workflows for pathogen detection using NIST RM 8376 in CSF and stool samples, finding workflow-dependent strain discrimination and sample-agnostic detection responses.

This study demonstrates that extracellular antibiotic resistance genes (eARGs) can be taken up and expressed by gut microbes, promoting antibiotic resistance propagation through natural transformation.

The paper discusses considerations for performance metrics in metagenomic NGS analyses, emphasizing the need for taxon-specific evaluation and appropriate summary metrics.
