BALF was collected from 3-4 mice in each group on day 1 and day 5 after infection. Each BALF was analyzed to determine cytokine concentrations by ELISA. aP < 0.05 versus control by Student’s t-test. bP < 0.01 versus control by Student’s t-test. cP < 0.05 versus TBBPA by Student’s t-test. dP < 0.01 versus TBBPA by Student’s t-test.
