^aData are averages of infections performed in duplicate. MAGI cells were infected with 10² to 10⁴ infectious virions, as determined by sMAGI assay. A value of 0 indicates that no cells were infected when cultured with a minimum of 10⁴ infectious virions. 

^bRNA, virions associated with vRNA; TCID_sMAGI, titers of virus stocks with sMAGI indicator cells (infectious virions/ml).
