<p><strong>Abstract.</strong> Gram-positive bacteria Listeria monocytogenes (LM) the causative agent of listeriosis is one of the pathogens entering to the human organism by food products. The listeriosis is one of the oldest experimental infection and LM is the classic object for study of cell immunity mechanisms. It was established that virulent bacteria L. monocytogenes induce infected immune cells to avoid own protective response. The authors conducted experiments to study changes in immune response indicators in mice in the different stages of infection (during 3–5 days) caused by L. monocytogenes EGDe (wt) strain and bacteria of isogeneic strains with mutations in genes controlled production of PAMPs (d28, i28). Analysis of published data and obtained results of this study allows to make a conclusion that immune response in listeriosis plays an important role and it depends on pathogen strain, bacteria doses and another condition of infection. Conducted study can be useful in case of choosing of treatment tactic of disease caused by Listeria monocytogenes, and, probable another diseases, caused by intracellular bacteria.</p
