FIGURE 5.
Survival analysis, viral RNA detection in tissues, and gross pathology findings of EBIV-challenged mice. (A) Survival curve of mice challenged with serial dilutions of EBIV. Adult mice (n = 5 per group, replicated three times) were challenged intraperitoneally with 106 PFU (dark blue), 104 PFU (dark green), and 102 PFU (dark red) of EBIV. (B) The viral RNA copies in blood, brain, kidney, liver, and spleen tissues were detected by quantitative RT-PCR, and the brain tissue presented a significant difference (*P < 0.05) compared to the other tested tissues. (C) In situ picture of organs in EBIV-infected animals with hemorrhaging and mock-infected animals.
