摘要:
The present application describes a novel, advantageous purification method which guarantees the embryonation capability and the viability of a worm egg suspension. The T. suis worm eggs are first treated in a non-embryonated condition in a sulfuric acid solution at about <;= ph 2. Bacteria and viruses are thereby killed successfully. The germination number of yeasts and fungi is reduced. In a second step, the pH-value is increased and an orally tolerated preservative is added. Yeasts and fungi are thereby killed successfully. The suspension medium used in the second purification step can then be used as a culture medium for additional production (embryonation) and storage.
