Unit 6, Protists and Malaria CS
Show Answers:

  1. Amoebiasis
    Diarrhoeal disease caused by several types of amoeboid protists
  2. Cryptosporidiosis
    A diarrhoeal disease caused by members of the genus Cryptosporidium
  3. Cysts
    Highly resistant structures formed by many parasitic protists, which enhances survival and transfer to new hosts
  4. Dysentry
    • Inflammation of the gut which produces fatty diarrhoea that may contain pus and mucus, and may be accompanied by abdominal cramps. 
    • Entamoeba histolytica amoebiasis
  5. Encystment
    • The process that occurs when a parasitic protist forms a cyst.
    • Can be instigated by environmental factors, such as change in pH.
  6. Excystment
    The process in which a parasitic cyst releases the vegetative form of the protist, again can be initiated by environmental factors.
  7. Flagellates
    • Protists that possess flagella during the adult stages of their life cycles
    • Giardiasis, Trichsomiasis, Trypanosomes, Leishmaniasis.
  8. Giardiasis
    A diarrhoeal disease caused by Giardia spp.
  9. Keratitis
    Inflammation of the cornea, caused by a variety of microbes, including Acanthamoeba.
  10. Oocyst
    A zygote produced by fusion of gametes in the apicomplexans (protists), which produces infective haploid spores by meiosis (sporogeny)
  11. Parasitaemia
    Any condition where parasites are present within the blood. The extent of parasitaemia can be quantified by counting the number of parasites per millilitre of blood, or by calculating the percentage of red blood cells that are infected.
  12. Protozoa
    Single-celled protists that have animal-like cells and are unable to photosynthesise.
  13. Schizogony
    Type of mitosis used by apicomplexans to produce many infective organisms.
  14. Sporogony
    Type of meiosis in apicomplexans that forms infective haploid spores.
  15. Toxoplasmosis
    Name given to any infection with the parasite Toxoplasma Gondii. This organism is found throughout the world in many birds and mammals, but it's definitive host is the Cat, since asexual reproduction of T. Gondii is confined to them.
  16. Trophozoite
    The vegetative form of a protist parasite, released from a cyst.
  17. Trypanosomiasis
    Disease caused by members of the genus Trynamosoma, including sleeping sickness in Africa, and Chagas disease in south America.
  18. Anthroponisis
    A disease that is spread from humans to other animals, such as malaria
  19. Passive immunity
    Immunity in which antibodies are transferred from one individual to another, either by mother to fetus or artificially by injecting antibodies.
  20. Enzyme-linked immunosorbent assay
    Diagnostic technique, involving serum samples which undergo various treatments before showing colour reactions based on the antibodies present.
