Figure 2From: Inhibitory effect of essential oils obtained from plants grown in Colombia on yellow fever virus replication in vitroIncrease of direct yellow fever virus (YFV) inactivation by the presence of essential oil in the supernatant of virus-infected cells culture. YFV previously incubated with serial dilutions of essential oil (Figure 1) was replicated in Vero cells at 37°C in M-199 medium containing varied concentration of essential oil. 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
