Chastek paralysis is a dietary disease, primarily affecting foxes, caused by consuming certain species of raw fish. It is an acute, paralytic, and often fatal condition.
Understanding Chastek Paralysis
Chastek paralysis is a thiamine (vitamin B1) deficiency resulting from the presence of the enzyme thiaminase in certain raw fish. This enzyme breaks down thiamine, preventing its absorption and leading to deficiency.
Key Aspects:
- Cause: Consumption of raw fish containing thiaminase.
- Affected Animals: Primarily foxes, but can also affect other animals.
- Symptoms: Paralysis, neurological dysfunction.
- Outcome: Often fatal if untreated.
Thiaminase and Raw Fish
Thiaminase is an enzyme that breaks down thiamine. Some fish species naturally contain this enzyme, posing a risk when consumed raw. The reference states the disease is caused by "incorporating certain species of raw fishes into the diet."
Prevention and Treatment
The reference states that chastek paralysis "may be prevented or cured by supplemented thiamine." This highlights the importance of adequate thiamine intake or avoiding raw fish known to contain thiaminase.
Prevention Strategies:
- Avoid feeding raw fish known to contain thiaminase.
- Supplement the diet with thiamine.
- Cook fish thoroughly to deactivate thiaminase.
Treatment:
- Administer thiamine injections.
