1 Neutrophil chemotaxis in response to zymosan-activated serum, a source of C5a, was depressed (days 0 through 5, 77 +/- 4 percent of control, P less than 0.001; days 6 through 8, 70 +/- 4 percent, P less than 0.001; days 9 through 13, 74 +/- 3 percent, P less than 0.001; days 14 through 19, 90 +/- 4 percent, P less than 0.01; and days 20 through 50, 97 +/- 3 percent, P not significant) and inversely correlated with CR1- and CR3-dependent fluorescence (r = -0.559, P less than 0.001; and r = -0.709, P less than 0.001, respectively).

2 The correlation between this increase and the depression of chemotaxis in response to zymosan-activated serum suggests that C5a is responsible for systemic neutrophil activation, which may contribute to the increased susceptibility to infection of patients with burns.
