It is now well known that the toxin of Clostridium botulinum type E can be altered by some proteolytic enzyme so that its activity is increased. On the other hand, attempts to activate types A and B toxins in the same manner have been unsuccessful. More recently, however, BONVENTRE and KEMPE observed that the toxicity of young cell extract of type A or B organisms was much enhanced by treatment with trypsin, and they suggested the presence of so called potential toxin or protoxin in these extracts. In the previous work,9) the present author also confirmed the presence of type A protoxin and observed that culture filtrates of the organisms contained a certain factor which enhances the toxicity of the protoxin preparation. Besides, it was emp...
