Influence of cadmium and zinc on the mice resistance to Listeria monocytogenes infection.

Unlabelled: The objective of this study was to examine the effect of chronic exposure to cadmium and zinc on the mice resistance to experimental Listeria monocytogenes infection.

Materials And Methods: At the day beginning of experiment outbred mice were injected with suspension of bacteria and 8 weeks were given the following oral intake treatment: control group (n=28) deionized drinking water, Cd- group (n=37) water containing CdCl2 10 mg/l and Cd+Zn- group (n=33) water containing CdCl2 10 mg/l and ZnSO4 100 mg/l. The delayed type hypersensitivity was evaluated by the inflammatory response during so-called "foot" test.
