Abstract excerpt
Shigella flexneri grown to stationary phase has the ability to survive for several hours at pH 2.5. This acid resistance, which may contribute to the low infective dose associated with shigellosis, is dependent upon the expression of the stationary-phase-specific sigma factor sigma S. Using rando...
