glossinavirus glossinavirus glossinavirus is a genus of viruses, in the family hytrosaviridae. glossina sp serve as natural hosts. there is only one species in this genus: glossina hytrosavirus. diseases associated with this genus include: partial sterility due to ovarian abnormalities or to testicular degeneration; can be asymptomatic in laboratory colonies. glossinavirus virus classification (unranked): virus realm: incertae sedis kingdom: incertae sedis phylum: incertae sedis class: naldaviricetes order: lefavirales family: hytrosaviridae genus: glossinavirus structure viruses in the genus glossinavirus are enveloped, with rod-shaped geometries. the diameter is around 50 nm. genomes are circular, around 190kb in length. the genome has 160 open reading frames. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation glossinavirusrod-shapedenvelopedcircularmonopartite life cycle viral replication is nuclear. dna-templated transcription is the method of transcription. glossina species serve as the natural host. transmission routes are parental. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission glossinavirusinsects: tsetse fliesepithelium: secretory salivary glands; ovarioles; gonadshorizontal; verticalhorizontal; verticalnucleusnucleushorizontal; vertical
