Chlamydiamicrovirus

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

  • Chlamydia virus Chp1
  • Chlamydia virus Chp2
  • Chlamydia virus CPAR39
  • Chlamydia virus CPG1

Structure

Viruses in Chlamydiamicrovirus are non-enveloped, with icosahedral and round geometries, and T=1 symmetry. The diameter is around 30 nm. Genomes are circular, around 6.1kb in length.[1]

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 chlamidia serve as the natural host. Transmission routes are passive diffusion.[1]
