Correct Answer: Filarial nematode worms (e.g., Wuchereria bancrofti) transmitted by mosquitoes
Explanation
Given data
- Disease: Filaria (lymphatic filariasis).
- Ask: Causative agent.
Concept/Approach Lymphatic filariasis is caused by filarial nematodes such as Wuchereria bancrofti and Brugia spp., typically transmitted by Culex, Anopheles, or Aedes mosquitoes.
Reasoning • Worm infection (helminth) → not bacterial, protozoal, or fungal. • Vector: mosquitoes inject larvae that mature in lymphatics.
Final Answer Filarial nematode worms (e.g., Wuchereria bancrofti) transmitted by mosquitoes
