Abstract

The Zaire subtype of Ebola virus (EBO-Z) is lethal for newborn mice, but adult mice are resistant to the virus, which prevents their use as an animal model of lethal Ebola infection. We serially passed EBO-Z virus in progressively older suckling mice, eventually obtaining a plaque-purified virus that was lethal for mature, immunocompetent BALB/c and C57BL/6 inbred and ICR (CD-1) outbred mice. Pathologic changes in the liver and spleen of infected mice resembled those in EBOZ-infected primates. Virus titers in these tissues reached 109 pfu/g. The LD50 of mouse-adapted EBO-Z virus inoculated into the peritoneal cavity was ~1 virion. Mice were resistant to large doses of the same virus inoculated subcutaneously, intradermally, or intramuscularly. Mice injected peripherally with mouse-adapted or intraperitoneally with non-adapted EBO-Z virus resisted subsequent challenge with mouse-adapted virus.
