[Changes in the functional activity of oxygen-dependent bactericidal macrophage systems during interaction with Yersinia pestis].

In this work the capacity of Y. pestis, depending on their plasmid composition, for inhibiting the action of the main oxygen-dependent bactericidal systems of macrophages is shown. The data on the modulating influence of Y. pestis on the activity of superoxide dismutase, myeloperoxidase and catalase, the most important enzymes of the synthesis and transformation of cytocidal oxygen radicals, are presented.
