Characterization of the RpoS status of clinical isolates of Salmonella enterica.

Applied and environmental microbiology - 1 Aug 2003

Robbe-Saule Véronique, Algorta Gabriela, Rouilhac Isabelle, Norel Françoise

Abstract excerpt

The stationary-phase-inducible sigma factor, sigma(S) (RpoS), is the master regulator of the general stress response in Salmonella and is required for virulence in mice. rpoS mutants can frequently be isolated from highly passaged laboratory strains of Salmonella: We examined the rpoS status of 116 human clinical isolates of Salmonella, including 41 Salmonella enterica serotype Typhi strains isolated from blood,...
