A new phlebovirus (Bunyaviridae family, Phlebovirus genus), provisionally designed Chize virus, was isolated from a nymph of Ixodes (Trichotoixodes) frontalis collected on a wren (Troglodytes troglodytes) found dead in the Chize forest, western France. Chize virus produced a lethal encephalitis in one-day-old mice and cytopathic effect (CPE) in Vero cells. Extracellular particles with a mean diameter of 105 nm with surface spikes characteristic of Uukuniemi (UUK) serogroup viruses were observed in Vero cells. Chize virus reacted in complement-fixation test with several UUK serogroup viruses but was readily distinguished from all registered viruses in the serogroup. I. frontalis is highly specific for birds and unlikely to transmit Chize virus to humans or domestic animals; the pathogenicity of the new virus to wild birds remains to be clarified.
