It beginswith an introduction to parasitology, coveringdefinitions of animal associations (phoresis, commensalism, mutualism, parasitism, predation), host-parasite relationships (specificity, physiological, morphological, immunological and behavioral adaptations), parasite effects on hosts, host defenses, and biological cycles (direct or indirect). The course thendetails the classification and study of numerousparasites: 1. ParasiticProtozoa: o Sarcomastigophora:Trypanosoma (trypanosomiasis/sleeping sickness), Leishmania (visceral and cutaneousleishmaniasis), Giardia (giardiasis), Trichomonas (trichomoniasis). o Apicomplexa: Plasmodium (malaria), Toxoplasma (toxoplasmosis), Eimeria (coccidiosis). o Sarcodina: Entamoeba histolytica (intestinal and hepaticamoebiasis). o Ciliates:Balantidium coli (balantidiasis). 2. ParasiticMetazoa: o Platyhelminthes:Trematodes (Fasciolahepatica, Schistosomahaematobium) and Cestodes (Taeniasaginata, T. solium, Echinococcusgranulosus, Diphyllobothriumlatum). o Nemathelminthes (Nematodes):Enterobiusvermicularis, Trichuristrichiura, Trichinella spiralis, Ankylostomaduodenale, Necatoramericanus, Ascaris lumbricoides. o Arthropods:Insects (Anoplura: lice; Siphonaptera: fleas; Diptera: mosquitoes of genera Aedes and Culex). Each parasite isdescribed in terms of morphology, life cycle, symptoms, diagnosis, treatment, and prophylaxis.enParasitology ; Protozoa; Metazoan; Host; Vector; Direct life cycle; Indirect life cycle; Host specificity; Parasitic adaptations; Zoonosis; Trypanosoma; Leishmania; Giardia; Trichomonas; Plasmodium; malaria; Toxoplasma; Entamoeba; Amoebiasis; Balantidium; Platyhelminthes; Trematodes; Fasciola; Schistosoma; Schistosomiasis; Cestodes; Taenia; Echinococcus; hydatidcyst; Diphyllobothrium; Nemathelminthes; Ascaris; Enterobius; Trichuris; Trichinella; Hookworm; Ankylostoma; Arthropods; Lice; fleas; Mosquitoes; Anopheles; Prophylaxis; ParasitologicaldiagnosisOther
