phenotype observed in females
phenotype observed in males
N normal phenotype
mortality/aging
• 14 of 16 mice die following infection with Thogoto virus

immune system
• following Thogoto virus infection, titers of 107.5 are detected in 50% of tissues
• following Thogoto virus infection, livers become pale, yellow, swollen, and friable at 72 to 96 hours
• following Thogoto virus infection, cellular degeneration in the liver is characterized by acidophilic hyalinization of the cytoplasm, pyknotic, or karyorrhetic nuclei and the formation of typical Councilman bodies
• following Thogoto virus infection, liver necrosis occurs
• IFN treatment only slightly inhibits or delays Thogoto virus multiplication in embryo cells

mortality/aging
• decreased lethality is observed in mice challenged with influenza A virus or VSV
• mice infected with VSV by an intracerebal route have longer mean survival times (2.7 days vs. 1.5)
• no lethality is observed in mice challenged with Thogoto virus while all the littermate controls died
• mice infected with influenza A virus by an intracerebal route have longer mean survival times (6.0 days vs. 3.9)
• mice infected with pneumotropic influenza A virus have increased rates of survival (33.3% vs 0%) for wild-type controls

immune system
• supernatant of embryonic fibroblasts infected with VSV contains 10-40 fold less infectious particles 25 hours after infection
• decreased lethality is observed in mice challenged with influenza A virus or VSV
• mice infected with VSV by an intracerebal route have longer mean survival times (2.7 days vs. 1.5)
