Life Cycle[edit | edit source]
Viral replication is cytoplasmic. Entry into the host cell is achieved by attachment of the viral proteins to host receptors, which mediates endocytosis. Replication follows the DNA strand displacement model. DNA-templated transcription is the method of transcription. The virus exits the host cell by budding, and tubule-guided viral movement. Humans and birds serve as the natural host. Transmission routes are sexual, blood, and contact.
