FIG 1.
L. monocytogenes EGDe invaded the intestine and spread to systemic organs after foodborne infection of mice. (A) BALB/c/By/J (BALB) or C57BL/6J (B6) mice were fed 3 × 109 CFU of L. monocytogenes SD2900 (Eryr EGDe). Tissue-associated CFU (in ileum and colon) or total CFU was determined at the indicated time points. Data from two separate experiments were pooled (n = 9 or 10 per group); mean values ± standard deviations (SD) are shown. (B) Total CFU recovered from the spleen or liver of individual mice fed 3 × 109 CFU of L. monocytogenes SD2900 (data shown in panel A) or 3 × 109 L. monocytogenes InlAm. Horizontal lines indicate mean values for each group. Dashed horizontal lines indicate the limit of detection for each tissue.
