Titration of IBV Beaudette strain in embryonating eggs following treatment with 10-fold serial dilutions of QR448(a) starting at 0 (no dilution) to 1 × 10−7 in PBS, and PBS plus IBV (control) are presented. The 50% embryo infectious dose (EID50) titers reflect the average of two replicates. No reduction in virus titer was observed for IBV treated with the diluent (data not shown).
