Question

Name 3 ways that PI BVD calves shed virus?

a. Saliva, urine, and feces
b. Blood, nasal secretions, and milk
c. Respiratory droplets, semen, and vaginal secretions
d. Tears, synovial fluid, and ear wax

Answer 1

PI BVD calves predominantly shed the virus through saliva, urine and feces, blood, as well as other fluids like nasal secretions and milk.

Step-by-step explanation:

PI BVD (Persistent Infection with Bovine Viral Diarrhea) calves shed the virus through various bodily fluids and secretions. The three ways PI BVD calves shed virus are:

1. Saliva, which can be a mode of transmission through direct contact with other animals.
2. Urine and feces, which can contaminate the environment and facilitate indirect transmission to other animals.
3. Blood, which can be a source of infection through biting insects, needles, or medical procedures.

Other bodily fluids such as nasal secretions, milk, and fluids from the respiratory and urogenital tracts can also serve as vehicles for virus transmission from PI BVD calves to other animals.
