*pre denotes treatment before induction of pneumonia; post denotes treatment after induction of pneumonia. MoAb III/5-1 was administered 1 hour before induction of pneumonia.
Pneumonia was induced at 0 hours by intranasal instillation of 1 × 103 CFU of K pneumoniae B5055 as described in Materials and Methods.
PBS was administered either IV (at −1 hour) or sc (all other time points).
