Figure 5. B. anthracis spore and LT caused mortality.

Mortality of C57BL/6J mice after intravenous injection of different doses (0 to 1×10⁷ CFU) of B. anthracis spores within one-week interval is revealed (A) (n = 8). Aliquots of B. anthracis spores (1×10⁷ CFU) was subjected to photocatalysis on TiO₂ and TiO₂ (N) photocatalysts, respectively; spores in TiO₂ (N) groups induced less mortality in mice (△) compared to untreated (○) or TiO₂ (▾) groups (B) (n = 6). Aliquots of anthrax LT (500 µg PA : LF = 5∶1) was subjected to photocatalysis on TiO₂ and TiO₂ (N) photocatalysts, respectively; LT (100 µg/g) in TiO₂ (N) groups (△) induced less mortality in mice compared to untreated (○) or TiO₂ (▾) groups (C) (n = 6).
