Figure 1From: Inhibitory effect of essential oils obtained from plants grown in Colombia on yellow fever virus replication in vitroDirect inactivation of essential oils from Colombian plants on yellow fever virus (YFV). About 9.5 × 104 PFU of YFV were incubated for 24 h at 4°C with concentrations of essential oil and then were adsorbed on Vero cells. Virus titers in supernatants of cell cultures were determined by plaque assays method at 48 h after adsorption. The data represent the means for three replicate samples of two independent experiment. Error bars indicate standard deviations.Back to article page
