Study Notes

Intestinal Parasites

  • Enterobius vermicularis (Pinworms): Female worms migrate to anus and lay eggs, diagnosed with scotch tape test on anus, treated with Pyrantel pamoate.

Hookworms

  • Ancylostoma duodenale and Necator americanus: Found in rural southern US, can enter bloodstream through bare feet, larvae travel to lungs and then GI tract, causing iron deficiency anemia.

Ascaris lumbricoides

  • Large Intestinal Worm: Eats eggs, larvae migrate to lungs through gut wall and bloodstream, then return to gut to become adults, causing malnutrition and respiratory symptoms, diagnosed by finding eggs in stool, treated with Pyrantel pamoate and Albendazole.

Strongyloides stercoralis

  • Autoinfection: Penetrates skin on bottom of feet, goes to lungs then GI tract, can cause hyperinfection in immunocompromised individuals, diagnosed by finding larvae in stool, treated with Albendazole.

Trichinella spiralis

  • Found in Pork and Bear Meat: Causes periorbital edema, vomiting, and fever, forms cysts in striated muscle cells, diagnosed by finding eosinophilia, treated with Albendazole.
