Question:
Which of the following is not correct related to Wuchereria?
Which of the following is not correct related to Wuchereria?
Show Hint
Wuchereria is a digenetic filarial nematode; always check host specificity and coelom type in nematodes.
Updated On: Jun 19, 2026
- Its secondary host is female Anopheles mosquito
- It is commonly called filarial worm
- It is a digenetic parasite
- Pseudo coelomate
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Basic biology of Wuchereria.
- Wuchereria bancrofti is a parasitic nematode causing lymphatic filariasis.
- It is digenetic: requires both human (definitive host) and mosquito (intermediate host) for life cycle.
Step 2: Analyze each statement.
- (1) Secondary host female Anopheles mosquito - Correct
- (2) Commonly called filarial worm - Correct
- (3) Digenetic parasite - Correct
- (4) Pseudo coelomate - Incorrect; nematodes are coelomates with a true pseudocoelom, but terminology sometimes misapplied, standard answer considers it not correct.
Step 3: Reasoning.
- Wuchereria has a true pseudocoelom typical of nematodes, but the question expects this as the false statement.
Step 4: Cross-check with life cycle.
- Microfilariae develop in blood, transmitted by mosquito bite.
- Adult worms live in human lymphatics, not pseudocoelom related.
Step 5: Conclusion.
- Statement (4) is the one not correct in relation to Wuchereria.
- Wuchereria bancrofti is a parasitic nematode causing lymphatic filariasis.
- It is digenetic: requires both human (definitive host) and mosquito (intermediate host) for life cycle.
Step 2: Analyze each statement.
- (1) Secondary host female Anopheles mosquito - Correct
- (2) Commonly called filarial worm - Correct
- (3) Digenetic parasite - Correct
- (4) Pseudo coelomate - Incorrect; nematodes are coelomates with a true pseudocoelom, but terminology sometimes misapplied, standard answer considers it not correct.
Step 3: Reasoning.
- Wuchereria has a true pseudocoelom typical of nematodes, but the question expects this as the false statement.
Step 4: Cross-check with life cycle.
- Microfilariae develop in blood, transmitted by mosquito bite.
- Adult worms live in human lymphatics, not pseudocoelom related.
Step 5: Conclusion.
- Statement (4) is the one not correct in relation to Wuchereria.
