Final answer:
The severe consequence of ingestion of the Clostridium botulinum toxin is paralysis, leading to flaccid paralysis of the muscles and respiratory failure. The answer is option B.
Step-by-step explanation:
The severe consequence of ingestion of the Clostridium botulinum toxin is paralysis. When the toxin is absorbed through the gastrointestinal tract, it causes progressive flaccid paralysis, leading to a gradual weakening and loss of control over the muscles. This paralysis can eventually result in death from respiratory failure.
For example, a patient with botulism may experience symptoms such as blurred vision, drooping eyelids, difficulty swallowing, abdominal cramps, nausea, vomiting, constipation, and possibly diarrhea. The paralysis affects the muscles of the upper airway, diaphragm, and chest, ultimately causing respiratory failure.
