Abstract:
:The candidacidal activity (CA) of peritoneal cells (PC) in vitro was used as a measure of nonspecific microbicidal activity of phagocytes after intraperitoneal injection of mice with different adjuvants. Dilutions of PC were incubated with constant numbers of C. parapsilosis in a 96-well culture plate. The PC number causing 50% reduction of yeast colonies formed after 48 hr at 37 degrees C was called 1 CA50 unit. CA was expressed in CA50 units per 10(6) PC. Optimal reduction of the number of viable candida cells in vitro was established within 1.5 hr while 50% reduction was reached after 0.5 hr. In this test CA was, within limits, independent of the number of viable candida cells added per well (22 to 152 yeast cells), of the concentration of fetal calf serum (1-20%) and of the presence of heat-labile serum components. The CA of PC of individual mice was measured 6, 24, and 96 hr after injection of an adjuvant. In most instances optimal CA was observed 6 hr after administration of adjuvant and varied from 3.7 (methylamine) to 50 (Corynebacterium parvum strain 4982) units. With respect to the titer and duration of CA, the adjuvants were arranged in the following order of increasing efficacy: methylamine, heparin, polyol L 121, suramin, dextran sulfate, polyol L 101, dimethyldioctadecylammonium bromide, Liquoid, heat-killed Listeria monocytogenes, formalin-killed C. parvum strain 10387, and strain 4982. The CA induced by the latter strain persisted at least till 96 hr after injection. The induction of CA was accompanied by recruitment of polymorphonuclear cells. The contribution of distinct phagocytic effector cells to CA and the correlation between modulation of the specific and nonspecific immunity are discussed.
