Serum-dependent killing of SEn in patients with CKD and controls.
Killing curves of SEn strain D24954 by sera from A—a sub-group of cohort 1 with highest anti-LPS IgG titres: 10 patients with CKD and 9 controls; B–all patients with CKD and controls from cohort 2 (n = 25 and 20 respectively). Negative values correspond to a reduction in SEn compared with starting concentration. Antibody-depleted young healthy control serum (used as standard) served as a negative control. Error bars represent the mean +/- standard error of the mean.
