Number of <i>L</i>. <i>monocytogenes</i> in the target organs of Zn- and atRA-supplemented mice.

<p>Mice were injected intraperitoneally with Zn, atRA or a combination of both compounds. Twenty-four hours after the last dose, the mice were infected intravenously with 10⁴/100 μl per mouse. CFU was measured in the liver and spleen 48 h after infection. The experiment was performed three times with four mice per group each time. Control mice received corn oil alone. Data are mean ± SD values of 12 mice per group. Statistically significant differences, compared with each group, are indicated by asterisks.
