Botulism is caused by?

Correct option is D

Sol. Botulism is a rare but serious illness caused by Clostridium botulinum, which releases a powerful neurotoxin. It blocks nerve signals to muscles, leading to flaccid paralysis. Improperly canned or preserved foods are common sources. Immediate medical treatment is critical to prevent respiratory failure.
Explanation of each option:
· (a) Staphylococci – Causes skin infections, boils, and sometimes food poisoning, but not botulism.
· (b) Salmonellosis – Caused by Salmonella bacteria, which results in diarrhea and fever, not paralysis.
· (c) Clostridium tetani – Causes tetanus, leading to spastic paralysis, unlike botulism's flaccid type.
· (d) Clostridium botulinum – Correct. Responsible for botulism due to neurotoxin affecting nerve-muscle communication.
