brevihamaparvovirus brevihamaparvovirus brevihamaparvovirus is a genus of viruses in subfamily hamaparvovirinae of the family parvoviridae. mosquitoes serve as natural hosts. there are two species in this genus. brevihamaparvovirus virus classification (unranked): virus realm: monodnaviria kingdom: shotokuvirae phylum: cossaviricota class: quintoviricetes order: piccovirales family: parvoviridae subfamily: hamaparvovirinae genus: brevihamaparvovirus taxonomy the following two species are assigned to the genus: dipteran brevihamaparvovirus 1 dipteran brevihamaparvovirus 2 structure viruses in genus brevihamaparvovirus are non-enveloped and have t=1 icosahedral symmetry. the diameter is around 21-22 nm. genomes are linear, around 4kb in length. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation brevihamaparvovirusicosahedralt=1non-envelopedlinearnone life cycle viral replication is nuclear. entry into the host cell is achieved by attachment to host receptors, which mediates clathrin-mediated endocytosis. replication follows the rolling-hairpin model. dna-templated transcription, with some alternative splicing mechanism is the method of transcription. mosquitoes serve as the natural host. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission brevihamaparvovirusinsects: dipteranoneclathrin-mediated endocytosiscell lysisnucleusnucleusunknown
