FIG 1.

Neutrophil discovery and elimination of S. aureus attached to a serum-coated glass surface. Representative images from time 0 h (top row) and time 4 h (bottom row) from experiments with no neutrophils (A and B), low density of neutrophils (C and D), high density of neutrophils (E and F), and high density of neutrophils with preformed bacterial aggregate wherein bacteria were allowed to grow for 3 h prior to neutrophil addition (G and H) (see also Videos S1 and S4 to S6 in the supplemental material).
