Parasitic Protozoa of medical interest. Life cycle of most important blood and tissue parasitic protozoa: haemoflagellates (Leishmania, Trypanosoma); human malaria parasites; Toxoplasma gondii; free-living amebae (Acanthamoeba, Naegleria). Life cycle of most important intestinal and urogenital parasitic protozoa: host-associated amebae (Entamoeba histolytica); ciliate (Balantidium coli); coccidia (Cryptosporidium, Cyclospora, Isospora); microsporidia; flagellates (Dientamoeba fragilis, Giardia intestinalis, Trichomonas vaginalis). Parasitic helminths of humans. Life cycle of most important blood and tissue parasitic helminths: cestodes (Echinococcus - hydatidosis; Taenia solium - cysticercosis); nematodes (Filaria, Trichinella, Toxocara); trematodes (Fasciola, Schistosoma).
Life cycle of most important intestinal parasitic helminths: cestodes (Diphyllobotrium latum, Hymenolepis nana, Taenia saginata, Taenia solium); nematodes (Enterobius vermicularis, Ascaris lumbricoides, Ancylostoma, Strongyloides stercoralis, Trichuris trichiura).
