Abstract excerpt
Salmonella enterica serovar Typhi uses type IVB pili to facilitate eukaryotic cell invasion. Here, we compare environmental and genetic controls on pil operon transcription with those regulating viaB genes required for Vi antigen expression. Transcription of pil occurs only in the late logarithmic and stationary phases of bacterial growth while viaB expression occurs in the logarithmic growth phase. Expression of...
