Aging is associated with more efficient killing of complement-opsonized pneumococci by PMNs. (A) The percentage of complement-opsonized S. pneumoniae TIGR4 killed upon a 45-min incubation with PMNs isolated from young and elderly donors was determined by comparing surviving CFU to a no PMN control. Shown are the averages of triplicate reactions from 6 young donors and 8 elderly donors within the same experiment. Significance was determined by unpaired student's t-test. (B) Pearson correlation analysis revealed a significant (p < 0.05) correlation between PMN bacterial killing and age, denoted by “^*.”
