bdellomicrovirus bdellomicrovirus bdellomicrovirus is a genus of viruses, in the family microviridae, in the subfamily gokushovirinae. bdellovibrio bacteria serve as natural hosts. there are two species in this genus. bdellomicrovirus virus classification (unranked): virus realm: monodnaviria kingdom: sangervirae phylum: phixviricota class: malgrandaviricetes order: petitvirales family: microviridae subfamily: gokushovirinae genus: bdellomicrovirus species bdellovibrio virus mac1 bdellovibrio virus mh2k structure viruses in bdellomicrovirus are non-enveloped, with icosahedral and round geometries, and t=1 symmetry. the diameter is around 30 nm. genomes are circular, around 4.5kb in length. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation bdellomicrovirusicosahedralt=1non-envelopedcircularmonopartite life cycle viral replication is cytoplasmic. entry into the host cell is achieved by pilus-mediated adsorption into the host cell. replication follows the ssdna rolling circle model. dna templated transcription is the method of transcription. the virus exits the host cell by bacteria lysis. bdellovibrio bacteria serve as the natural host. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission bdellomicrovirusbdellovibrio bacterianonepilus adsorptionlysiscytoplasmcytoplasmpilus
