Detection of the Xanthi Chryso-like Virus in New Geographical Area and a Novel Arthropod Carrier

Abstract

Here, we report on a serendipitous finding of a chryso-like virus associated with Culex pipiens mosquitos in the course of study aimed to detect and characterize West Nile virus (WNV) circulating in mosquitos in Serbia, Southern Europe. Upon initial detection of unexpected product in a PCR protocol for partial WNV NS5 gene amplification, further confirmation and identification was obtained through additional PCR and Sanger sequencing experiments. Bioinformatic and phylogenetic analysis identified the obtained sequences as Xanthi chryso-like virus (XCLV). The finding is particular for the fact that it associates XCLV with a new potential vector species and documents a novel geographical area of its distribution. © 2023 by the authors.
