Eukaryotes comprise animals, plants, and fungi – which are mostly multicellular . Primitive eukaryotes are also important in medicine and veterinary science: some cause human and animal diseases such as giardia (hikers’ diarrhea) and trypanosomiasis (African sleeping sickness). Yet others live in symbiotic relationships with other organisms: the flagellate Streblomastix shown above lives in the intestines of termites, and it and several other protists assist in the digestion of wood.
