We assessed the growth kinetics of our two reporter-expressing ZIKVs in BHK-21 cells following infection at a MOI of 1 with rZIKV-eGFP or rZIKV-nLUC, or with rZIKV for comparison; viral titers were determined by immunofocus assays on naïve BHK-21 cells by using a rabbit α-NS3 antiserum. This evidence concerns the gene KRAS and infection.
