摘要

A novel type A botulinum toxin preparation isprovided. A neuromuscular transmission blocking agentcomprising as an active ingredient a highly purified type Abotulinum toxin from Clostridium botulinum as infantbotulism pathogen and a medicament for treating a diseasewith muscle overactivity comprising as an active ingredientsaid toxin.
