AIIMS 2019 Zoology Vectors and Diseases MCQ Question

Filariasis is caused by parasitic worms of the genus Wuchereria, which are transmitted through the bites of infected mosquitoes, not Trichoderma, a genus of fungi. Option B is incorrect because amoebiasis is primarily transmitted through contaminated food and water, with the housefly acting as a mechanical vector rather than a direct cause. Option C is misleading as Culex mosquitoes are vectors for diseases like lymphatic filariasis, while Anopheles mosquitoes are the true vectors for malaria. Lastly, option D is incorrect because ascariasis, caused by the roundworm Ascaris lumbricoides, is transmitted via the fecal-oral route, not through droplet infection.
