Fig 7. Kaplan-Meier plots showing differences in survival of C57/BL/6 mice after intra-tracheal challenge with P. gingivalis, P. gingivalis plus pyocyanin, PBS, and PBS plus pyocyanin.

Fig 7

Mice (10 animals per group) were inoculated with 3×109 CFU of wild-type P. gingivalis W83 (Pg) or P. gingivalis plus 40 μg pyocyanin (Pg+PCN) into the lungs via the trachea. Control groups were challenged with PBS or with PBS plus 40 μg pyocyanin (PCN). The survival of mice was monitored during whole time of procedure. Log-rank test, n = 10 in all cases, **P<0.01 and ***P<0.001 for control PBS or PBS+PCN-inoculated, and P. gingivalis- or P. gingivalis+PCN-inoculated animals, respectively.
