LPS Levels in Chamber Fluid Samples and/or Sera of C57BL/6J and Cybb−/− Mice during the Course of the Experiment
(A) LPS levels in the chamber fluid samples of C57BL/6J and Cybb−/− mice. On day 0, the two mouse strains were inoculated with 100-μl volume, 1 × 109 CFU/ml P. gingivalis strain W83 or Rbr− mutant strain.
(B) LPS levels in the chamber fluid samples and sera of mice on day 3 after challenge. The mice were challenged with a lethal dose (100-μl volume, 1 × 109 CFU/ml) of P. gingivalis strain W83. The data are presented as the means ± SD from the results obtained for three mice per group. *p < 0.05; **p < 0.01; as determined by Student's t test.
