Overexpression of fimYZ leads to repression of invasion of HEp-2 cells. Strains were grown under low-oxygen and high-osmolarity conditions. The deletion of hilE restored S. enterica serovar Typhimurium invasiveness in HEp-2 cells even when fimYZ were overexpressed. Values are presented as a percentage of invasion by the wild-type strain, with the invasiveness of that strain being set to 100%.
