Diagnostic test for Bovine Viral Diarrhea Virus (BVDV Ab)

Bovine viral diarrhea (BVDV) is a viral disease of cattle and other ruminants that is caused by the bovine viral diarrhea virus (BVDV). It affects cattle of any age. BVDV has two types of infection: transient and persistent. Transient infection last for less than 2 weeks. Animals become less productive, they shed the virus and are susceptible to other diseases. Animals become immune to BVDV after they recover. Persistent infection (PI) is lifelong. When a pregnant cow is infected with BVDV during the first few weeks (30-125 days) of gestation, the virus gets through the placenta and infects the unborn calf, the calf becomes a PI. PI animals shed the virus through their whole life and infect other animals. Persistently infected animals shed 1000 times more virus than a transient one and are the maim source of BVDV transmissions. BVDV may be shed in excretions and secretions, including nasal discharge, tears, saliva, urine, feces, milk and semen. Problems caused by BVD: bulls infertility during infection, abortions, stillbirths, diarrhea, bruising, bleeding lesions, difficulty with blood clotting, giving birth to weak and infected calves.
There is no specific anti-BVDV therapy.
