用C型肉毒梭菌培养物和培养滤液对小鼠进行口服给药。

Res Vet Sci. 1987 Jul;43(1):134-5.

In two of 14 tests in which adult mice were dosed per os, whole broth culture of Clostridium botulinum type C was more lethal than culture sterilised by membrane filtration. The results indicated that occasionally--though not usually--significant bacterial multiplication and toxigenesis occurred in the gut.

在对成年小鼠进行经口给药的14项试验中的2项中，C型肉毒梭菌的全菌肉汤培养物比经膜过滤灭菌的培养物毒性更强。结果表明，虽然通常不会，但偶尔肠道内会发生显著的细菌繁殖和产毒。
