Disease Vectors and Pathogens

Malaria is caused by the Plasmodium parasite, which is a type of protozoa transmitted by the Anopheles mosquito.

Taenia solium is a digenetic endoparasitic platyhelminth whose primary host is man and secondary host is pig.

It is the non-feeding larval stage of Fascicola hepatica or liver fluke.

African trypanosomiasis is a parasitic disease transmitted by the tsetse fly. It gets its nickname ‘sleeping sickness’ because symptoms can include a disturbed sleep pattern.

Trichonympha is a genus of parabasalid protists that live in the intestines of many, if not most, termite species. They are symbiotes, in that they break down the cellulose in the wood and plant fibers their hosts eat.

Unlike most other protozoans, sporozoans have no cilia or flagella. All species are parasitic and have elaborate life cycles, often requiring more than one host. The best-known sporozoan is Plasmodium falciparum, the causative organism of malaria.

A parasite lives on or inside a host and derives nutrients at the host's expense. Lice living on a human scalp is a classic example of an ectoparasitic relationship.

Malaria is a protozoan disease transmitted to humans through the bite of an infected female Anopheles mosquito. The other diseases listed have different transmission routes.

Trypanosoma is a genus of kinetoplastids, a monophyletic group of unicellular parasitic flagellate protozoa, which are responsible for African sleeping sickness. The other options are bacteria or other types of parasites not associated with this specific disease.
