Parasite Morphology and Vector Map

Protozoa, helminths, vectors, and eggs

  1. Parasite clue family

    Sort first by protozoan versus helminth, then use vector, cyst, egg, and tissue-stage vocabulary.

    Reference Giardia duodenalis · Plasmodium species · Schistosoma species · Taenia species

    1. Protozoa

      Giardia, Entamoeba, Cryptosporidium, Plasmodium, Toxoplasma, Trypanosoma, and Leishmania are common morphology/lifecycle anchors.

      Reference Giardia duodenalis · Entamoeba histolytica · Cryptosporidium · Plasmodium species · Toxoplasma gondii · Trypanosoma cruzi · Leishmania species

    2. Helminths

      Ascaris, Taenia, and Schistosoma separate by nematode, cestode, and trematode vocabulary.

      Reference Ascaris lumbricoides · Taenia species · Schistosoma species

    3. Vector or host term

      Use mosquito, sandfly, triatomine, snail, cat, and reservoir-host terms as lifecycle vocabulary.

      Reference Plasmodium species · Leishmania species · Trypanosoma cruzi · Schistosoma species · Toxoplasma gondii · Vector, reservoir, and definitive host
