The Vi capsular polysaccharide enables Salmonella enterica serovar typhi to evade microbe-guided neutrophil chemotaxis.
Salmonella enterica serovar Typhi (S.Typhi) causes typhoid fever, a disseminated infection, while the Nets closely related pathogen S.enterica serovar Typhimurium (S.Typhimurium) is associated with a localized gastroenteritis in humans.Here we investigated whether both pathogens differ in the chemotactic response they induce in neutrophils using a
