    Study Notes

    Parasite Definitions

    • Incidental (accidental) parasite: Parasite that is not typically found in a specific host, but may accidentally be hosted there.
    • Amoebiasis: Infection caused by Entamoeba histolytica parasite.
    • Parasitism: Relationship where one organism (parasite) benefits at the expense of another (host).
    • Intermediate host: Organism that harbors the larval stage of a parasite.
    • Encystation: Process by which a protozoan forms a cyst.
    • Cercaria larva: Larval stage of some trematodes.
    • Ascaris lumbricoides: A roundworm that causes ascariasis.
    • Balantidium coli: A ciliated protozoan that causes balantidiasis.
    • Definitive host: Organism that harbors the adult stage of a parasite.

    Parasite Morphology and Differences

    • Amastigotes and promastigotes: Different morphological forms of Leishmania.
    • Extraintestinal amoebiasis: Amoebiasis that occurs outside of the intestines.
    • Egg or nits stage of pediculus: Stage where pediculus species lay their eggs.

    Life Cycles

    • Asexual phase of Plasmodium life cycle: Flow chart describing the asexual reproduction of Plasmodium in the host.
    • Sexual phase of Plasmodium life cycle: Flow chart describing the sexual reproduction of Plasmodium in the host.
    • Fasciola hepatica: Description and information about the liver fluke parasite
    • Ascaris lumbricoides life cycle: Paragraph describing the life cycle of this roundworm.
    • Pre-erythrocytic cycle of Plasmodium: Brief description of this step in the life cycle.
    • Trematodes characteristics: Basic characteristics.
    • Classification of helminths: Brief account
    • Entamoeba histolytica life cycle: Flow chart of its life cycle
    • Differences between hard and soft ticks: Information and description

    Infective Stage of Plasmodium

    • Infective stage of plasmodium: Sporozoite is the infective stage of Plasmodium for humans.

    Cercaria Larvae and Paragonimus

    • Cercaria larvae: Belong to the Fasciola hepatica.
    • Paragonimus species: Liver fluke.
