FIG. 2.
Splenomegaly (A) and splenic bacterial loads (B) in mice at 28 days p.i. (A) All infected animals developed significant splenomegaly compared to controls, and infected SCID mice had significantly larger spleens than CB-17 mice (P < 0.05). (B) Mice infected with group IV, V, and VI isolates had significantly fewer bacteria than those infected with group I isolates (P < 0.05). *, P < 0.05. The error bars indicate standard deviations.
