Figure 1. In vitro growth kinetics of tick-borne flaviviruses.

BHK21 cells were infected with either OHFV Guriev, KFDV P9605, AHFV 2003, or AHFV Zaki-1 at an MOI of 0.01, and supernatant (A) and cell-associated (B) fractions were harvested daily for 5 days. Titers are expressed as TCID₅₀ ml⁻¹, and error bars represent standard deviations.
