Study Notes

Dracunculus Medinesis (Dracunculiasis)

  • Dracunculus medinesis is a type of parasite, also known as Dracula.
  • It is transmitted through water contaminated with copepods containing larvae.
  • Diagnosis is made by observing worms coming out of the skin, often accompanied by red ulcers.
  • Treatment involves pulling out the worms with spinning matchsticks.

Onchocerca Volvulus (River Blindness)

  • Onchocerca volvulus is a type of parasite, transmitted by the black fly's bite.
  • The larvae burrow into the host, causing microfilariae to form, which can lead to hyper and hypo-pigmented spots.
  • Can cause blindness, also known as river blindness.
  • Eosinophilia is a common feature of the disease.
  • Diagnosed through skin biopsy under a microscope.

Wucheria Bancrofti (Lymphatic Filariasis)

  • Wucheria bancrofti is a type of parasite, also known as the witch.
  • Causes lymphadenopathy, characterized by swelling of the lymph nodes.
  • Can lead to elephantiasis, a condition characterized by swelling of the limbs.
  • Microfilariae travel to the lungs, causing a hypersensitivity reaction.
  • Mosquito is the intermediate host of the parasite.
  • Diagnosed through thick blood smear examination.

Toxicara Canis (Toxocariasis)

  • Toxicara canis is a type of parasite, also known as the wolfman.
  • Transmitted through the feces of dogs or cats.
  • The parasitic larvae never mature and can get into the eye, causing blindness.
  • Eosinophilia is a common feature of the disease.

Loa Loa (African Eye Worm)

  • Loa Loa is a type of parasite, also known as the swamp creature.
  • Causes transient angioedema, characterized by localized subcutaneous swellings.
  • Worms can be seen wriggling across the eyeball.
  • Diagnosed through blood smear examination.

Treatment Options

  • Diethylcarbamazine is used to treat Wucheria bancrofti and Loa Loa infections.
  • Albendozole is used to treat Toxicara canis and Loa Loa infections.
  • Ivermectin is used to treat Onchocerca volvulus infections.

Dracunculus Medinesis (Dracunculiasis)

  • Dracunculus medinesis is a type of parasite, also known as Dracula.
  • It is transmitted through water contaminated with copepods containing larvae.
  • Diagnosis is made by observing worms coming out of the skin, often accompanied by red ulcers.
  • Treatment involves pulling out the worms with spinning matchsticks.

  • Transmitted through the feces of dogs or cats.
  • The parasitic larvae never mature and can get into the eye, causing blindness.
  • Eosinophilia is a common feature of the disease.

  • Causes transient angioedema, characterized by localized subcutaneous swellings.
  • Worms can be seen wriggling across the eyeball.
  • Diagnosed through blood smear examination.

Treatment Options

  • Diethylcarbamazine is used to treat Wucheria bancrofti and Loa Loa infections.
  • Albendozole is used to treat Toxicara canis and Loa Loa infections.
  • Ivermectin is used to treat Onchocerca volvulus infections.
