    <p>At day 2 after infection with 5×10<sup>5</sup> pfu of <i>R. australis</i>, 50 µg of ODN control (ODN 1826 control) and CpG-B (ODN 1826) per mouse were injected i.v. into WT and IDO<sup>−/−</sup> mice (4 mice per group). At day 5 post-infection, spleen cells (1×10<sup>6</sup>/ml) from individual mice were restimulated with PMA/Ionomycin/GolgiStop for 5 h. Multiple intracellular cytokines as indicated were measured in CD4<sup>+</sup> and CD8<sup>+</sup> T cells. The percentages of intracellular cytokine production in gated T cells were shown as mean ± SD in the corner (A). Representative statistical data are shown from one of three independent experiments. * <i>p</i><0.05 (B).</p

    <p>Dual immunofluorescence staining of SFG rickettsiae (red) and VE-cadherin (green) using dual wave lengths filter system reveals that, compared to normal controls, <i>R. montanensis</i> infection (10 MOI) resulted in degradation of the density of VE-cadherin, suggesting disruption in the continuity of VE-cadherin at neighbouring areas at 72 hr post-infection.</p
