  Bovine Viral Diarrhea Virus - BVDV
• BVDV first recognized in 1946 in upstate New York
• Now identified worldwide
• Antibody prevalence studies show as high as 60-70% prevalence of BVDV in herds (Bovine Viral Diarrhea Virus, Goyal and Ridpath, Blackwell Publishing)
• Estimated that 70-90% of acute/transient infections are subclinical (Ames et al.,1986)
• Costs associated with BVDV infections are incurred from:
  • Reproductive losses
  • Increased Morbidity
  • Increased Mortality
  • Reduced Performance
• Estimated losses of $35-$56 per calf (Ridpath)
• Dairy industry losses estimated at $65 per calf (Ellis AABP 04)
• BVDV causes immunosuppression which allows for greater virulence of common pathogens
• Acts synergistically with other pathogens to cause more severe pneumonia
  • BVDV infection alone caused mild pneumonia involving 2-7% of lung
  • M. hemolytica infection alone caused pneumonia involving 15% of lung
  • BVDV infection followed by M. hemolytica caused pneumonia involving 40-75% of lung
