Invasion of Int407 cells and survival in J774 macrophages. (A) The indicated S. Typhimurium strains were tested for invasion of Int407 cells via gentamicin protection assay. The ratio of percent invasion of each strain to that of the control was calculated and graphed. The ΔSPI-1 strain contains a deletion of the SPI-1 genes required for full invasion of Int407 cells. The ΔSPI-1 and ΔydcI mutant strains were compared to the WT for ratio calculation. The pBAD18, pBAD18+ydcI, and pBAD18+lacZ strains were compared to the WT pBAD18 strain under the corresponding arabinose condition for ratio calculation. (B) The indicated strains were tested for survival in J774 macrophages over a period of 18 to 20 h via gentamicin protection assay. The ratio of the percent survival of each strain to that of the control was calculated and graphed. For ratio calculations, the ΔydcI mutant strain was compared to the WT and the pBAD18+ydcI strain was compared to the pBAD18 strain.
