Neutrophil bacterial killing by cells from a patient with CGD. CGD neutrophils were incubated with bacteria (1:1) at 37°C. Viable bacterial counts were determined at 0, 30, and 120 min postinfection. Data presented are percentages of bacteria relative to the starting inoculum at each time point. ■, B. multivorans ATCC 17616; □, B. multivorans 26D7; ●, B. multivorans JTC; ▴, P. aeruginosa M2 as a susceptible control (43).
