Titration of IBV Beaudette strain in Vero E6 cells following treatment with 10-fold serial dilutions of QR448(a) starting at 1 × 10−3 to 1 × 10−9 in cell culture maintenance medium and cell culture maintenance medium plus IBV alone (control) are presented. The 50% tissue culture infectious dose (TCID50) titers reflect the average of three replicates. No reduction in virus titer was observed for IBV treated with the diluent (data not shown).
