Ct values for virus-specific nucleoprotein RNA in mice engrafted with rhesus monkey immune cells infected with diverse simarteriviruses causing hemorrhagic disease. NSG-SGM3 (NOD.Cg-Prkdcscid Il2rgtm1Wjl Tg[CMV-IL3,CSF2,KITLG]1Eav/MloySzJ) mice were engrafted with fetal CD34+-enriched hematopoietic stem and progenitor cells isolated from rhesus monkeys. Engrafted and unengrafted NSG-SGM3 transgenic mice and background-matched wild-type NOR/LtJ mice were injected intraperitoneally and intravenously with 1 of 4 viruses: A) simian hemorrhagic fever virus; B) Kibale red colobus monkey virus 1; C) Pebjah virus; or D) Southwest baboon virus 1. Production of virus-specific nucleoprotein RNA in blood was measured over time by using quantitative reverse transcription PCR. Dotted lines indicates limit of detection. Ct, cycle threshold.
