FIG. 4.

Spleens of mice infected with the high dose of NM II: splenomegaly (A) and bacterial genome numbers (B) in the spleen at 28 DPI. The results (means ± standard deviations) are expressed as the percentage of spleen weight based on the body weight (A) and the number of C. burnetii genomes in the whole spleen (B). An asterisk indicates that the P value is <0.05. SCID and SCIDbg mice were significantly different from PBS-inoculated groups (P < 0.05) for splenomegaly (A). Double dagger, not detected.
