Correlation between the number of intracellular bacteria and the presence of cell death markers in individual phagocytes in the livers of wild-type and tlr4^−/− mice infected with Salmonella enterica: the mean intracellular bacterial load and [range], per marker-positive and marker-negative cell (C57BL/6 and tlr4^−/−) at 72 and 96 hr postinfection (p.i.)

	Mean intracellular bacterial load per cell
C57BL/6 caspase-3-negative (72 hr)	1·42 [1…21] (n = 2946)
C57BL/6 caspase-3-positive (72 hr)	3·15 [1…16] (n = 54)
C57BL/6 caspase-3-negative (96 hr)	1·79 [1…29] (n = 2948)
C57BL/6 caspase-3-positive (96 hr)	2·58 [1…15] (n = 52)
tlr4−/− caspase-3-negative (72 hr)	1·44 [1…27] (n = 3000)
tlr4−/− caspase-3-positive (72 hr)	Not detected
tlr4−/− caspase-3-negative (96 hr)	1·68 [1…35] (n = 2993)
tlr4−/− caspase-3-positive (96 hr)	4·57 [1…18] (n = 7)
