Influence of Mouse Age on the Outcome of Mouse-Adapted Ebola Virus Infection

	CD-1 survival (n = 6)

	Survival	Time to death, days after infection	Survival	Time to death, days after infection
6 wk	0%	5–7	0%	6–7

Groups of 6 mice of the noted ages were intraperitoneally infected with 10 focus-forming units of mouse-adapted Ebola virus (1000 lethal dose causing 50% mortality), with or without additional daily intraperitoneal injections of Dulbecco’s modified Eagle medium.
