    • C.

      Sheep tissue

    Correct Answer

    The virus strain used to produce vaccine COGLAPEST® is:

    • A.

      THIVERVAL strain

    • B.

      Chinese strain

    Correct Answer
    A. THIVERVAL strain
    Explanation
    Thiverval strain is
    - Cold and labile strain (Mastered multiplication at body temperature, No horizontal spreading - pig to pig - in the environment)
    - Stable strain : no reversion of virulence (Unchanged after 10 serial passages in tissue culture at 37oC)

  • 3. 

    What does COGLAPEST® contain pHENOL RED for?

    • A.

      Phenol Red is used as a dye

    • C.

      Both of them

    Correct Answer
    C. Both of them
    Explanation
    COGLAPEST® contains PHENOL RED as dye to monitor the quality of the diluent used.
    - Optimum pH from 6 to 8
    - Solution: light pink

  • 4. 

    One dose of COGLAPEST® contains:

    • A.

      10 PD50

    • B.

      100 PD50

    • C.

      1000 PD50

    Correct Answer
    C. 1000 PD50
    Explanation
    To use a vaccine which exceeds 100 PD50 per dose of CSF vaccine is necessary (OIE recommendation) :
    - To achieve a uniform protection of sows and suckling piglets
    - To limit the risk of neutralization of the vaccine strain with Maternal Derived Antibodies
    - To stop the circulation of virus and thus to eradicate the risk of intermediate strains and their subsequent immunotolerant animals

    • D.

      Safety after injection

    • E.

      All of them

    Correct Answer
    E. All of them
    Explanation
    FEATURES & BENEFITS of COGLAPEST® are:
    - Cold and labile strain
    + Cold: mastered multiplication at body temperature
    + Labile: no horizontal spreading (pig to pig, in the environment)
    - Stable strain: no reversion of virulence
    Unchanged after 10 serial passages in tissue culture at 37oC
