Comparisons of Ct values for different viruses infecting cells from rhesus monkeys in study of diverse simarteriviruses causing hemorrhagic disease. PBMCs and splenocytes were isolated from rhesus monkeys, infected with different simarteriviruses, and analyzed for infection by using quantitative reverse transcription PCR. Dots for each cell type and numbers in parentheses indicate number of experiments performed for each virus. Horizontal lines between dots indicate mean Ct values for each group. Statistical significance was determined by using 1-way analysis of variance. A, adherent; Ct, cycle threshold; KRCV-1, Kibale red colobus monkey virus 1; N, nonadherent; PBJV, Pebjah virus; PBMCs, peripheral blood mononuclear cells; SHFV, simian hemorrhagic fever virus.
