Linear, dsDNA genome of about 330 kb with crosslinked hairpin ends. PBCV-1 genome encode for approximately 700 ORFs.




  1. Virus attaches to host receptors , inducing release of viral genome into the cell.
  2. Migration of the DNA core to the nucleus?
  3. Synthesis of early proteins.
  4. Replication of genomic DNA..
  5. Late proteins synthesis, assembly of new virions in the cytoplasm
  6. Cell lysis and virion release in the extracellular space.
