Question

  Wuchereria bancrofti
• B.
  Ancylostoma duodenale
• C.
  Taenia solium
• D.
  Salmonella typhimurium

Answer 1

The correct option is A

Wuchereria bancrofti
Symptoms like deformities and thickening of lower limbs and genital organs occurs in Lymphatic filariasis. It is a parasitic disease caused by three species of microscopic, thread-like worms. The adult worms only live in the human lymph system. The lymph system maintains the body's fluid balance and fights infections.

One of the causative agent of lymphatic filariasis (LF) is mosquito-borne filarial nematodes Wuchereria bancrofti (Bancroftian filariasis). The larval form of the parasite transmits the disease to humans by the bite of a mosquito.

Salmonella typhimurium can only infect humans. It causes typhoid fever.

Taenia solium tapeworm infections can lead to cysticercosis, which is a disease that can cause seizures.

Intestinal hookworm disease in humans is caused by Ancylostoma duodenale


Therefore, the correct answer is "option a".
