The bactericidal activity against Pseudomonas aeruginosa strains isolated from cystic fibrosis patients was determined in a 10% concentration of normal serum or autologous cystic fibrosis serum. Of the 167 strains tested, 77 (46%) were sensitive (greater than 95% killed) in normal serum. Mucoid strains were more frequently sensitive than nonmucoid strains. Twenty-three sensitive strains tested in ethyleneglycoltetraacetic acid-chelated serum were resistant (less than 10% killed), suggesting only classical pathway activation. Absorption of cystic fibrosis serum with the autologous P. aeruginosa strain resulted in decreased killing by that serum. All sera, including the chelated and absorbed sera, had comparable total hemolytic complement levels. Patients in poor clinical condition (5 out of 12), in contrast to patients in good or moderate condition(1 out of 30), were more likely to have P. aeruginosa strains that were serum resistant in autologous serum but sensitive in normal serum. Sera from these five patients in poor clinical condition were capable of killing heterologous P. aeruginosa strains. These results suggest the presence of a protective or "blocking" activity in serum from some patients in poor clinical conditions. This association of a blocking activity with clinical condition may signal a transition point in the progression of cystic fibrosis lung disease and thus may be another contributory factor in the failure of the cystic fibrosis host to control infection.
