Phenotype Homozygous State abnormal immunoglobulin level: levels of IgG2a and IgG2b neutralizing antibodies are reduced relative to controls after secondary infection with Ectromelia virus increased susceptibility to viral infection: slightly more susceptible to MCMV viral infection than controls increased susceptibility to Ectromelia virus 100% mortality by day 6-12 after primary infection infection elevated virus titers in all organs tested after primary infection but much improved after secondary infections survive secondary infections
