Question

Botulism caused by Clostridium botulinum affects the
A. Intestine
B. Lymph glands
C. Neuromuscular junction
D. Spleen

Answer 1

Hint: Clostridium botulinum is an anaerobic, rod-shaped spore-forming bacterium that produces a protein with characteristic neurotoxicity. Clostridium botulinum is a bacterium that produces perilous poisons (botulinum poisons) under low-oxygen conditions. Botulinum poisons are one of the most deadly substances known. Botulinum poisons block nerve works and can prompt respiratory and solid loss of motion.

Complete Answer:
- Clostridium botulinum is a soil living bacteria. Botulism is an uncommon and possibly deadly disease brought about by a poison created by the bacterium Clostridium botulinum. The malady starts with shortcoming, obscured vision, feeling tired, and inconvenience talking.
- This may then be trailed by shortcoming of the arms, chest muscles, and legs. It causes Botulism in which the spores of Clostridium botulinum releases botulinum toxin which is taken in the bloodstream.
- Botulinum toxin blocks the release of acetylcholine at the neuromuscular junction. Impulses are not transferred to the muscles thus causing paralysis. They are anaerobic, meaning they live and grow in low oxygen conditions.
- The bacteria form protective spores when conditions for survival are poor. The spore has a hard protective coating that encases the key parts of the bacterium and has layers of protective membranes.

Hence the correct answer is option C.

Note: Botulism is of three types. They are food-borne botulism, wound botulism, and infant botulism. Food-borne botulism is caused by the intake of food that contains preformed botulinum toxin. The major source of this disease is the homemade canned food that gets contaminated by the bacteria. Wound botulism is caused by contamination of the wound by spores of the bacteria. Infant botulism is the type of botulism shown by infants after the intake of food with spores of clostridium botulinum bacteria.
