Effect of preincubation of S epidermidis strain 10b with αSesC-IgGs on phagocytosis of planktonic (□) and sessile (■) bacteria by human neutrophils. Bacteria grown in planktonic form or attached to catheter fragments were tested for their ability to survive in human blood after preincubation with preimmune IgGs or αSesC-IgGs. Surviving bacteria were measured by viable counting. The data are presented as the mean log10 of surviving CFU. The data for each group are the average of six measurements in two independent experiments. The error bars represent the standard deviation of the measurements.
