Figure 4: Experimental findings of mice given equine antisera or F(ab′)2.

Groups of 8 BALB/c mice were administered IP with either F(ab′)2, twice daily for 3 days starting at 1 or 2 dpi with MA-EBOV, or one injection of antisera at 1 or 2 dpi. Injections contained 200 μg of antisera or F(ab′)2. (A) The survival and (B) percentage weight change are shown for mice administered F(ab′)2, whereas (C) the survival and (D) percentage weight change are shown for animals given equine antisera.
