Generation and Application of a Luciferase Reporter Virus Based on Yellow Fever Virus 17D.

ABSTRACT: Yellow fever virus (YFV) is a re-emerging virus that can cause life-threatening yellow fever disease in humans. Despite the availability of an effective vaccine, little is known about the replication mechanism of YFV, and there are still no available specific anti-YFV medicines. Herein, by introducing the Renilla luciferase gene (Rluc) into an infectious clone of YFV vaccine strain 17D, we generated a recombinant virus 17D-Rluc.2A via reverse genetics approaches. The 17D-Rluc.2A had similar plaque morphology and comparable in vitro growth characteristics with its parental strain. Importantly, the reporter luciferase was efficiently expressed in 17D-Rluc.2A-infected mammalian and mosquito cells, and there was a good linear correlation between intracellular luciferase expression and extracel
