FIG. 3.

Serum AST (A) and ALT (B) levels after ConA treatment of K. pneumoniae infection. Groups of four mice were inoculated intragastrically with 2 × 10⁸ K. pneumoniae NK-5 cells per mouse. ConA (1 mg/kg of body weight) was administrated as described for Fig. 1A. The mice were sacrificed at different times postinfection, and the mouse serum samples were collected and detected as described in Materials and Methods. Treatments: ⋄, K. pneumoniae NK-5 only; ▪, K. pneumoniae NK-5 plus ConA (1 mg/kg); ▵, ConA (1 mg/kg) only. *, P < 0.05 compared with values determined for K. pneumoniae-treated mice.
