First detection of a Mesonivirus in Culex pipens in five countries around the Mediterranean basin [PDF]

, 2017
Culex pipiens is a mosquito vector of West Nile virus (WNV), the causing agent of West Nile fever. Epizooties of WNV have taken place in Europe, mainly in France, Italy and Spain, and in some instances, human cases have been diagnosed. However, beyond WNV, little is known on the viruses associated to Culex pipiens, above all on viruses non-pathogenic ...

Dianke virus: A new mesonivirus species isolated from mosquitoes in Eastern Senegal. [PDF]

Virus Res, 2020
An increasing number of insect-specific viruses are found around the world. Very recently, a new group of insect-specific viruses, the Mesoniviridae family, was discovered in Africa, Asia, North America and Australia. Here we report the first detection and isolation of a new virus belonging to Mesonivirus genus in Senegal, West Africa.

Classification, replication, and transcription of Nidovirales. [PDF]

Front Microbiol, 2023
Nidovirales is one order of RNA virus, with the largest single-stranded positive sense RNA genome enwrapped with membrane envelope. It comprises four families (Arterividae, Mesoniviridae, Roniviridae, and Coronaviridae) and has been circulating in humans

Structural basis for catalysis and substrate specificity of a 3C-like cysteine protease from a mosquito mesonivirus. [PDF]

Virology, 2019
Cavally virus (CavV) is a mosquito-borne plus-strand RNA virus in the family Mesoniviridae (order Nidovirales). We present X-ray structures for the CavV 3C-like protease (3CLpro), as a free enzyme and in complex with a peptide aldehyde inhibitor mimicking the P4-to-P1 residues of a natural substrate.

First Report of a Mesonivirus and Its Derived Small RNAs in an Aphid Species Aphis citricidus (Hemiptera: Aphididae), Implying Viral Infection Activity. [PDF]

J Insect Sci, 2020
Abstract We report a new positive-sense single-stranded RNA (ss RNA+) virus from the brown citrus aphid Aphis citricidus. The 20,300 nucleotide (nt)-long viral genome contains five open-reading frames and encodes six conserved domains (TM2, 3CLpro, TM3, RdRp, Zm, and HEL1).

Mechanism, structural and functional insights into nidovirus-induced double-membrane vesicles. [PDF]

Front Immunol
During infection, positive-stranded RNA causes a rearrangement of the host cell membrane, resulting in specialized membrane structure formation aiding viral genome replication. Double-membrane vesicles (DMVs), typical structures produced by virus-induced

Spatial scale influences the distribution of viral diversity in the eukaryotic virome of the mosquito Culex pipiens [PDF]

, 2023
Our knowledge of the diversity of eukaryotic viruses has recently undergone a massive expansion. This diversity could infuence host physiology through yet unknown phenomena of potential interest to the felds of health and food production.

Isolation and characterization of a novel mesonivirus from Culex mosquitoes in China. [PDF]

Virus Res, 2017
A new insect nidovirus (named Yichang virus) from the family Mesoniviridae was isolated, identified, and characterized from Culex mosquitoes in Hubei, China. Results showed a high number of viral RNA copies (up to 1011 copies/ml) within 48h in C6/36 cells.

Negeviruses reduce replication of alphaviruses during co-infection [PDF]

, 2021
Negeviruses are a group of insect-specific virus (ISV) that have been found in many arthropods. Their presence in important vector species led us to examine their interactions with arboviruses during co-infections.
