Question

Name four intestinal nematodes

Q122 marksShort Notes

Answer

Four intestinal nematodes:

  1. Ascaris lumbricoides — the largest intestinal nematode, causes ascariasis, soil-transmitted via egg ingestion.
  2. Ancylostoma duodenale / Necator americanus (hookworm) — causes iron-deficiency anaemia via blood feeding; transmitted percutaneously via skin penetration by larvae.
  3. Trichuris trichiura (whipworm) — causes trichuriasis, characteristic barrel-shaped eggs with polar plugs.
  4. Enterobius vermicularis (pinworm) — causes perianal itching, diagnosed via perianal swab rather than stool.

(Other valid example: Strongyloides stercoralis, notable for its unique autoinfective life cycle and risk of hyperinfection syndrome in immunocompromised hosts.)
