WISH-barcoding of Salmonella Typhimurium ATCC14028s strains for population dynamics studies in vivo

Background Barcoding of isogenic strains is a powerful approach to assess pathogen population dynamics during infection. Here, we adapted WISH-barcoding to Salmonella Typhimurium ATCC14028s to evaluate its suitability for pooled infection experiments in streptomycin-pretreated mo...

Autoinducer-2 functions as both a quorum-sensing and metabolic signal in Escherichia coli

ABSTRACT Bacteria integrate diverse environmental signals to coordinate behavior, yet the relationship between nutrient sensing and quorum sensing (QS) remains incompletely understood. Autoinducer-2 (AI-2) is unique among QS signals in that its production is tightly linked to cen...
