Survival and growth of L. monocytogenes in organs of Se-adequate or Se-deficient C57BL/6 mice. Survival and growth of L. monocytogenes in the intestine (A), lymph nodes (B), liver (C), spleen (D) and brain (E) of Se-adequate (Se+) and Se-deficient (Se-) inoculated orally with 5 × 10⁹ CFU bacteria. Bacterial growth was followed in the organs at 24, 48, 72, 96,120 and 144 h post infection. Results are expressed as the mean concentration per group ± standard deviation (SD). *p < 0.05, **p < 0.01.
