Fig. 1 Distinct morbidity and mortality after MA-EBOV infection in CC-RIX mouse lines.
Distinct morbidity and mortality after MA-EBOV infection in CC-RIX mouse lines. (A) Percent of starting body weight over the course of infection in susceptible (red squares) and resistant (blue circles) mice. Data shown are mean ± SEM from five mice per CC-RIX line. (B) Kaplan-Meier survival curve for susceptible (red) and resistant (blue) mice. Five mice were used for each CC-RIX line. (C to F) Gross appearance of liver at necropsy in uninfected susceptible (C) and resistant (E) mice and on day 5 p.i. in susceptible (D) and resistant (F) mice. Angela L. Rasmussen et al.

Fig. 2 MA-EBOV replication in CC-RIX mouse lines.
MA-EBOV replication in CC-RIX mouse lines. (A and B) Quantitative real-time polymerase chain reaction showing the expression of MA-EBOV genomes relative to mouse 18S ribosomal RNA in spleen (A) and liver (B). Data shown are mean ± SEM for three mice per time point per RIX line. (C and D) Titration of infectious MA-EBOV in organ homogenates from spleen (C) and liver (D) quantified as FFUs per milliliter. No infectious virus was detected before day 3 p.i. Data shown are mean ± SEM from two experiments using two or three mice per time point per CC-RIX line. (E to H) Immunohistochemical staining for VP40 in resistant liver [(E) and (F)] and susceptible liver [(G) and (H)]. The arrows indicate representative hepatocyte morphology (t test, *P < 0.05).

Fig. 3 Quantification of coagulopathy and hemorrhage in CC-RIX mouse lines.
Quantification of coagulopathy and hemorrhage in CC-RIX mouse lines. (A to C) Coagulation times in seconds for thrombin (A), prothrombin (B), and activated partial thromboplastin (C) over the course of MA-EBOV infection. (D) Serum fibrinogen levels in CC-RIX mice over the course of MA-EBOV infection. All data shown are the mean ± SEM for two experiments including two to five animals per time point. (ANOVA with Tukey’s HSD post-hoc test; * P < 0.05, ** P < 0.05, *** P < ). Angela L. Rasmussen et al. Science 2014;346: Published by AAAS

Fig. 4 Distinct host responses associated with disease phenotype.
Distinct host responses associated with disease phenotype. (A and B) Number of differentially expressed genes either up-regulated (positive y axis) or down-regulated (negative y axis) relative to time-matched mock-infected samples in spleen (A) and liver (B).
