Group 3 biomedical importance of protozoa

Group 3: Biomedical importance of Protozoa

By: Ben, Sarah, Ryan, Lawrence, and Dory


Biomedical importance of protista water treatment

Biomedical Importance of Protista: Water Treatment

  • The biodegradation potential of ciliated protozoa allow natural waste-water treatment to be possible.

  • Protists feed off bacteria resulting in lower organic loads within waste water

  • Protozoa allow self-purification and matter cycling in natural ecosystems.


Pathogenic protozoa

Pathogenic Protozoa

  • giardia (genus)

  • African Sleeping Sickness:trypanosoma brucei

  • Malaria:plasmodium (genus)

  • Five species can be infected and transmitted by humans.


Giardia

giardia

  • Caused by 40 different species from the genus giardia

  • Most common waterborne illness in the country

  • Causes diarrhea and on occasion vomiting

  • Protist has two nuclei for 4 flagella

  • Cycles from ‘hibernating cyst’ to an active state of feeding and motility

  • The cyst protects it from extreme conditions while being transferred from host to host

  • The protist should only be active when inside host

Malaria

Malaria

  • Mosquito born infectious disease.

  • Two phases one that involves the liver and one that involves red blood cells.

  • In 2010 there were 219 million cases 2 million deaths estimated.

  • Antimalarial medications are available but no vaccine exists.


African sleeping sickness

African Sleeping Sickness

- Caused by protozoans from the genus trypanosom.

- The bloodborne sickness is transferred through the bite of a tsetse fly, from mother to fetus, and through infected needles.

- Infection is broken up into two stages

First Stage- Fever, headache, itching, and joint pain

Second Stage- Confusion, behavioral changes, poor coordination, disturbances in sleep cycle, death.
