[Changes in the antimicrobial potential of the phagocytosing cells of great gerbils in experimental plague].
The work deals with the results obtained in the study of the activity of the cytocidal systems of phagocytes in great gerbils under normal conditions and during the plague infectious process. The data have been analyzed in comparison with the corresponding characteristics of phagocytic activity in mice. Changes in the oxygen-dependent metabolism (ODM) of neutrophils and macrophages, responsible for the functioning of their oxygen-dependent cytocidal systems, in plague show features characteristic of the nonspecific systemic postaggression reaction (SPAR). In Y. pestis-sensitive animals (mice), changes in the ODM activity of phagocytes are manifested as shock of different severity. In great gerbils, these changes present as true SPAR. The degree of the sensitivity of animals to Y. pestis infection is mainly determined by the initial level of the activity of oxygen-sensitive cytocidal systems of neutrophils (determined in the nitro blue tetrazolium spontaneous reduction test). In great gerbils this level exceeds the corresponding characteristics in mice 2.6- to 8.7-fold.
