Clinical Effects



  • Limited data is available but BIV transmission is believed to be via contact with body fluids, such as milk and semen.

Pathological effects

  • BIV infection cycle begins when the free virus attaches to cell surface receptors. The viral RNA is released into the cytoplasm where the viral reverse transcriptase (RT) transcribes the genome into double-stranded DNA. This DNA forms a provirus which is transported to the nucleus and incorporated into the host genome. This provirus remains silent unless stress factors reactivate it via cellular signals.
  • When reactivated the DNA is converted into infectious RNA before infectious particles are assembled near the plasma membrane.

Other Host Effects

  • BIV infection can cause immunosuppression in some animals, making them more susceptible to other infections.


Control via animal

  • As BIV is believed to be transmitted through contact with infected body fluids any animals displaying clinical signs should be quarantined.
  • Other animals within the herd should be tested.


  • None available.
