    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.
