Reynolds induces early infiltration of PMNs into brain abscesses. Abscess-associated cells were recovered from mice (3–4 animal/group/time point) at days 1, 3 and 7 following S. aureus strain RN6390 or Reynolds infection using a Percoll gradient method and analyzed by FACS. Results are presented as the percent positive cells for each population pooled from three independent experiments (mean±SEM). Significant differences between S. aureus strain RN6390- and Reynolds-infected mice are denoted with asterisks (*, p<0.05).
