Delayed development of inflammatory milieu in lungs of O. tsutsugamushi CCR2-/- mice. CCR2-/- and C57BL/6 mice were infected with 5,000 sfu O. tsutsugamushi i.d. and sacrificed on days 0, 10, 14, 17 and 21 p.i. From homogenates of lung tissue, transcription of ifn-γ, inos and tnf-α, il-4, arg1 and ccl2 mRNA was measured by real-time PCR from tissue lysates and expressed as -fold induction at the indicated time points p.i. (A–F). Shown are pooled results from two independent experiments (total of n=6 mice per genotype and timepoint; mean ± SD). *p < 0.05; **p < 0.01; ***p < 0.001 by one-way ANOVA.
