Neutrophil-associated bacterial killing is reduced in CF ASL. Quantitative bacterial survival after incubating bacteria and neutrophils (ratio of 3:1) for 10 min at 37°C in normal (WT) ASL and cystic fibrosis (CF) ASL at 1/250 dilution. Data shown as mean ± SEM are from a minimum of six independent experiments. For each experiment, the colony counts were averaged from three plates. *P < 0.05.
