Chlamydiamicrovirus

Chlamydiamicrovirus is a genus of viruses, in the family Microviridae, in the subfamily Gokushovirinae. Various species of Chlamydia serve as natural hosts. There are four species in this genus.^[1][2]

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. Various species of Chlamydia serve as the natural host. Transmission routes are passive diffusion.^[1]
