FIG. 3.

Systemic bacterial burdens following gastric Salmonella infection. C57BL/6 and CCL2^−/− mice were fed 10⁸ virulent salmonellae. At 2 and 5 days postinfection, four mice were euthanized and the GALT (A and B), spleens (C and D), and livers (E and F) were homogenized and plated on LB agar plates to determine numbers of CFU. The horizontal bar shows the average number of CFU per group. The data are representative of three separate experiments. An asterisk denotes P < 0.05 comparing the bacterial counts of CCL2^−/− mice to those of wild-type mice.
