- 2.
The virus strain used to produce vaccine COGLAPEST® is:
- A.
THIVERVAL strain
- B.
Chinese strain
Correct Answer
A. THIVERVAL strainExplanation
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)Rate this question:

- 3.
What does COGLAPEST® contain pHENOL RED for?
- A.
Phenol Red is used as a dye
- B.
To monitor the quality of the diluent used
- C.
Both of them
Correct Answer

- 4.
One dose of COGLAPEST® contains:
- A.
10 PD50
- B.
100 PD50
- C.
1000 PD50
Correct Answer
C. 1000 PD50Explanation
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 animalsRate this question:

All of them
Correct Answer
E. All of themExplanation
FEATURES & BENEFITS of COGLAPEST® are:
- Cold and labile strain
