Identification and characterization of genetically divergent members of the newly established family Mesoniviridae.

ABSTRACT: The recently established family Mesoniviridae (order Nidovirales) contains a single species represented by two closely related viruses, Cavally virus (CavV) and Nam Dinh virus (NDiV), which were isolated from mosquitoes collected in Côte d'Ivoire and Vietnam, respectively. They represent the first nidoviruses to be discovered in insects. Here, we report the molecular characterization of four novel mesoniviruses, Hana virus, Méno virus, Nsé virus, and Moumo virus, all of which were identified in a geographical region in Côte d'Ivoire with high CavV prevalence. The viruses were found with prevalences between 0.5 and 2.8%, and genome sequence analyses and phylogenetic studies suggest that they represent at least three novel species. Electron microscopy revealed prominent club-shaped surface p
