 | | The bacterium Clostridium botulinum is a strictly anaerobic, spore-forming, gram-positive rod that excretes botulin, a potent neurotoxic exotoxin, during bacterial growth and autolysis. |
 | | Currently, 7 antigenic types of botulin are recognized: A through G. Types A, B, E, and F are the principal causes of botulism in humans; C and D occur primarily in birds and mammals. |
 | | The diagnosis of botulism is based on the presence of appropriate neurological signs and symptoms, results of laboratory tests to detect botulin, or culturing C botulinum from specimens of the patient’s stool, wound, blood, or other secretions. |
