Figure Legend Snippet: Compare NMI reinfection induced innate and adaptive cellular responses between PBS and different doses of primary NMI-infected mice. BALB/c mice were IP infected with PBS, 1 × 10 2 , 1 × 10 4 , or 1 × 10 5 GE of NMI bacteria. All dose of NMI-infected and PBS control mice were IP challenged with 1 × 10 7 GE of NMI bacteria at 35 days post primary NMI infection. In addition, naive BALB/c mice were used as uninfected normal mouse controls. The absolute cell numbers of macrophages plus monocytes, neutrophils, dendritic cells, B cells, CD8 + T cells, and CD4 + T cells in the spleen were determined by flow cytometry and compared between PBS control and primary NMI-infected mice at 14 days after NMI reinfection. (A) , macrophages plus monocytes (CD11b + CD11c − Ly6G − ). (B) , neutrophils (CD11b + Ly6G + ). (C) , Dendritic cells (CD11c + ). (D) , B cells (CD19 + ). (E) , CD8 + T cells (CD3 + CD8 + ). (F) , CD4 + T cells (CD3 + CD4 + ). Data presented in each group are the averages with SD for four mice, with error bars representing the SD from the means. *P < 0.05; **P < 0.01 and ****P < 0.0001 were determined by one-way ANOVA with Tukey’s post-test.
Techniques Used: Infection, Bacteria, Control, Flow Cytometry
Figure Legend Snippet: The protective efficacy of primary NMI-infection induced protection against NMI reinfection in B cell, T cell, CD4 + T cell or CD8 + T cell deficient mice. C57BL/6J WT and B cell, T cell, CD4 + T cell or CD8 + T cell deficient mice were IP infected with 1 × 10 4 GE of NMI bacteria and challenged with 1 × 10 7 GE of NMI bacteria at 35 days post-primary NMI-infection. Additionally, naive WT mice were mock infected with PBS and served as controls. Splenomegaly and bacterial burden in the spleen were measured at 14 days post-challenge. (A) , Relative body weights (current body weight/day 0 body weight) were measured throughout the challenge period. (B) , Splenomegaly (% of spleen weight/body weight). (C) , bacterial burden in the spleen was determined by real-time qPCR and is expressed as log10 C . burnetii com1 gene copy numbers. Data presented in each group are the averages with SD for five mice, with error bars representing the SD from the means. *P < 0.05; **P < 0.01; ***P < 0.001; and ****P < 0.0001 were determined by one-way ANOVA with Tukey’s post-test.
