Dynamics of non-specific antibacterial activity of the peritoneal cells of mice induced with Coxiella burnetii antigen.
It was found that primary immunization with Coxiella burnetii antigen increased mouse resistance to Salmonella typhimurium infection as evidenced by acceleration of bacterial elimination from the peritoneal cavity and a decrease in lethality of experimental animals. The existence of two rises of bactericidal activity of mouse peritoneal cells was ascertained: the "early" on days 1 and 2, and the "late" on day 14 after C. burnetii administration. The first rise was accompanied by some increase in the number of peritoneal cells as well as by some change of their qualitative representation. The second increase of antibacterial activity was detected during the pronounced cellular and humoral immune responses to C. burnetii.
