immune system
• mice infected with a mouse adapted (MA15) version of severe acute respiratory syndrome coronavirus (SARS-CoV) show enhanced lung damage compared to wild-type mice, showing increased perivascular inflammation with interstitial edema, and alveolar and interstitial spaces filled with proteinaceous fluid and inflammatory cells, however they show a similar weight loss, viral titer, and recovery as wild-type control mice
• aged mice (20-24 weeks old) show increased susceptibility to SARS-CoV infection compared to older wild-type mice, showing higher levels of lung damage, increased edema, perivascular cuffing, interstitial inflammation and cuffing around airways, and enhanced cellular proliferation in lungs
• aged mice infected with SARS-CoV show 80% lethality by 5 dpi compared to 30% lethality in wild-type controls

mortality/aging
• aged mice infected with SARS-CoV show 80% lethality by 5 dpi compared to 30% lethality in wild-type controls
