muscavirus muscavirus muscavirus is a genus of viruses, in the family hytrosaviridae. the fly musca domestica is the natural host. there is only one species in this genus: musca hytrosavirus. diseases associated with this genus include: salivary gland hypertrophy, and complete sterility of infected female flies by inhibiting eggs development. muscavirus virus classification (unranked): virus realm: incertae sedis kingdom: incertae sedis phylum: incertae sedis class: naldaviricetes order: lefavirales family: hytrosaviridae genus: muscavirus structure viruses in the genus muscavirus are enveloped, with rod-shaped geometries. the diameter is around 50 nm. genomes are circular, around 124kb in length. the genome has 108 open reading frames. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation muscavirusrod-shapedenvelopedcircularmonopartite life cycle viral replication is nuclear. dna-templated transcription is the method of transcription. musca domestica serve as the natural host. transmission routes are parental and contamination. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission muscavirusinsects: house fliesepithelium: secretory salivary glands; ovarioles; gonadscontact: food; horizontal; verticalbudding; horizontal; verticalnucleusnucleuscontact: food; horizontal; vertical
