Abstract

The influences of peritoneal macrophages induced by proteose peptone, Corynebacterium parvum (C. parvum) or Bacillus Calmette Guérin (BCG) on the initiation and development of immune responses and protection against Listeria monocytogenes infection were studied in mice. Mice treated intraperitoneally (i.p.) with proteose peptone 4 days previously showed much the same level of protection against an intraperitoneal infection with Listeria as untreated mice. Mice treated i.p. with C. parvum 4 days previously, of which peritoneal macrophages had increased abilities for intracellular killing of Listeria and 0-2 generation as compared with peptone-elicited macrophages, exhibited an enhanced resistance against the listerial infection. The degree of immune responses, as assessed by delayed footpad reaction (DFR), was rather depressed in these mice because C. parvum-activated macrophages acting as scavenger cells reduced the amount of effective antigenic stimulation. BCG-activated peritoneal macrophages from mice treated i.p. with BCG 14 days previously showed a strong ability for antigen presentation in correlation with increases in the number of la-bearing macrophages and in the level of interleukin 1 (IL 1) production. These mice showed an early appearance of DFR response and a markedly enhanced resistance against the listerial infection. These results suggested that the differences in macrophage activities as scavenger cells, cytokine-secreting cells and antigen presenting cells may account for the differences in the responsiveness against listerial infection in peptone-, C. parvum- and BCG-treated mice.
