(A) After 12, 24, and 96 hrs post infection, bacterial burdens were quantified in the lung homogenates of mice infected with 1.0× 106 CFU of EF3030 or JEN18 (**P=0.0022 for 12 hrs and *P=0.0157 for 24 hrs). (B) After 12, 24, and 96 hrs post infection, bacterial burdens were quantified in the BAL of mice infected with 1.0× 106 CFU of EF3030 or JEN18 (**P=0.0022 for 12 hrs and *P=0.0157 for 24 hrs). The horizontal bars indicate the medians. These data are representative of two independent experiments.
