A novel phase variant of the cholera pathogen shows stress-adaptive cryptic transcriptomic signatures.

Abstract excerpt

BACKGROUND: In a process known as phase variation, the marine bacterium and cholera pathogen Vibrio cholerae alternately expresses smooth or rugose colonial phenotypes, the latter being associated with advanced biofilm architecture and greater resistance to ecological stress. To define phase variation at the transcriptomic level in pandemic V. cholerae O1 El Tor strain N16961, we compared the RNA-seq-derived...
