All types can cause human disease, but type A, B and E are most common". (In Harrison & Ananthanarayan, eight types of C. botulinum A, B, CI, C2, D, E, F, G have been mentioned). . Toxin production in clostridium botulinum appears to be determined by presence of bacteriophage (at least in type C & D). .
