High-Yield Explanation
Eight types of C.botulinum have been identified (A, B, C1, C2, D, E, F and G) based on the immunological difference in the toxins produced by them.

An exception is a C2 toxin which shows enterotoxic activity while others are neurotoxins. Reference: Textbook of Microbiology; Anathanarayan and paniker's; 10th edition; Page no: 269
