['To demonstrate the role of RpoE during the later stage of hyperosmotic stress in Salmonella.', 'Expressions of SPI-1 and SPI-2 under hyperosmotic stress for 120 min were investigated by a microarray, and the invasion and intracellular survival of wild-type and ΔrpoE strains were compared. The global differential expression of bacterial proteins between the wild-type and ΔrpoE strains was examined after 120 min of hyperosmotic stress.', 'SPI-1 and SPI-2 were repressed, and the invasion and intracellular survival were defected in the ΔrpoE strain. Thirteen bacterial-associated proteins and 11 secreted proteins differed significantly between the wild-type and ΔrpoE strains.'] Does rpoE promote invasion and intracellular survival by regulating SPI-1 and SPI-2 in Salmonella enterica serovar Typhi?
