relationship between them. As a biological discipline, the scope of

parasitology is not determined by the organism or environment in question but by their way of life. This means it forms a synthesis of other disciplines, and draws on techniques from fields such as cell biology, bioinformatics, biochemistry, molecular biology, immunology, genetics, evolution and ecology.

where one organism, the parasite, lives on or in another

organism, the host, causing it some harm, and is adapted structurally to this way of life.

causes malaria. The four species infective to humans are P.

falciparum, P. malariae, P. vivax and P. ovale. Leishmania, unicellular organisms which cause leishmaniasis Entamoeba and Giardia, which cause intestinal infections (dysentery and diarrhoea) Multicellular organisms and intestinal worms (helminths) such as Schistosoma spp., Wuchereria bancrofti, Necator americanus (hookworm) and Taenia spp. (tapeworm) Ectoparasites such as ticks, scabies and lice Medical parasitology can involve drug development, epidemiological studies and study of zoonoses.

subphylum) Sarcodina. These organisms have streaming cytoplasm and use temporary

cytoplasmic extensions called pseudopodia in locomotion (called amoeboid movement) and feeding.
Sarcodina (phylum Protozoa, subphylum Sarcomastigophora) A superclass of protozoa which form pseudopodia for feeding and locomotion. There are three classes, and many orders. The majority of species live in marine aquatic environments but some occur in fresh water (and are important members of the soil fauna) and some are parasitic in the intestinal tracts of vertebrates and invertebrates. The superclass includes the Radiolaria, known from the Cambrian, and the Heliozoa, which are exclusively freshwater and have a fossil record that extends back only to the Pleistocene.
