Ectromelia virus provides a mouse model for smallpox where the virus and the host's immune response have co-evolved." "Using this model, our study investigated the role of the complement system during a poxvirus infection. By multiple inoculation routes, ectromelia virus caused increased mortality by 7 to 10 days post-infection in C57BL/6 mice that lack C3, the central component of the complement cascade.
