Novosviirus

Novosviirus is a genus of viruses in the order Mononegavirales, family Rhabdoviridae, and subfamily Sigmodirhabdinae. Viruses in this genus are characterized by their bullet-shaped morphology and single-stranded, negative-sense RNA genome. The name "novosviirus" is derived from the Latin word "novus" meaning new, and "svirus" meaning virus, reflecting its relatively recent discovery and classification.

These viruses are primarily transmitted by arthropod vectors, particularly mosquitoes. They have been identified in various insect species across different geographical regions. The genomic structure of novosviiruses typically includes genes encoding for nucleoprotein, phosphoprotein, matrix protein, glycoprotein, and RNA-dependent RNA polymerase. The glycoprotein, located on the viral envelope, plays a crucial role in host cell entry and is a target for the host's immune response.

While the specific host range and pathogenicity of most novosviiruses are still under investigation, some members of this genus have been associated with infections in insects, causing no apparent disease or mild symptoms. Research into novosviiruses is ongoing to understand their evolutionary relationships within the Rhabdoviridae family, their replication cycles, and their potential impact on insect populations and, indirectly, on broader ecosystems. The study of these viruses contributes to the broader field of virology and insect pathology.
