Dynamics of Vibrio cholerae abundance in Austrian saline lakes, assessed with quantitative solid-phase cytometry.

abstract：:Upon a wide range of stress conditions (e.g. nutrient, antibiotic, oxidative), a subpopulation of bacterial cells known as persisters survives by halting metabolism. These cells resuscitate rapidly to reconstitute infections once the stress is removed and nutrients are provided. However, how these dormant cells resusc...
