Bloodstream infections (BSIs) are common in hospitals, often life-threatening and increasing
in prevalence. Microorganisms in the blood are usually rapidly cleared by the immune …

Host bottlenecks prevent many infections before the onset of disease by eliminating
invading pathogens. By monitoring the diversity of a barcoded population of the diarrhea …

Enteric pathogens navigate distinct regional microenvironments within the intestine that cue
important adaptive behaviors. We investigated the response of Citrobacter rodentium, a …

Importance Proton-pump inhibitors (PPIs) have been associated with the risk of colonization
with drug-resistant bacteria; however, possible confounding by lifestyle-associated factors …

Listeria monocytogenes is a bacterial pathogen that can cause life-threatening central
nervous system (CNS) infections. While mechanisms by which L. monocytogenes and other …

By longitudinally following a large cohort of intercontinental travellers, this study highlights
the importance of considering multiple risk factors to comprehend post-infectious irritable …

Quorum Sensing (QS) is a form of cell-to-cell communication that enables bacteria to modify
behavior according to their population density. While QS has been proposed as a potential …

Bacterial populations often have complex spatial structures, which can impact their
evolution. Here, we study how spatial structure affects the evolution of antibiotic resistance in …

Transposon insertion sequencing (Tn-seq) is a powerful method for genome-scale
functional genetics in bacteria. However, its effectiveness is often limited by a lack of mutant …

Bacteremia, a leading cause of death, generally arises after bacteria establish infection in a
particular tissue and transit to secondary sites. Studying dissemination from primary sites by …
