Killer Protists

Rachel Heileson Tic Tac Toe


•The genus name for the single-celled parasite which causes malaria is Plasmodium. In the genus, there are five species which infect humans: Plasmodium falciparum (the most deadly kind), P. vivax, P. ovale, P. malariae and P. knowlesi.

-Malaria is a parasitic disease that involves high fevers, shaking chills, flu-like symptoms, and anemia which in severe cases can progress to coma or death.

-Malaria is a mosquito-borne infectious disease of humans and other animals.

-Disease transmission can be reduced by preventing mosquito bites by using mosquito nets and insect repellents, or with mosquito-control measures such as spraying insecticides and draining standing water

Trypanosoma; (trypanosoma brucei)

- causes African sleeping sickness.

- starts with with a fever and headaches, accompanied by vital organ dysfunction, is followed by the swelling of lymph nodes and ends with mental confusion, disruption of sleep cycle and extreme fatigue.

- It is transmitted by the tsetse fly's bite and takes over the lymphatic system.

- gradually crosses over to the blood stream and once it gets past the blood barrier of the brain, the protist kills the person it inhabits.

- All trypanosomes are heteroxenous

- Trypanosomes infect a variety of hosts and cause various diseases, including the fatal human diseases sleeping sickness, caused by Trypanosoma brucei, and Chagas disease, caused by Trypanosoma cruzi.

Entamoeba; (Entamoeba histolytica)

- causes amoebic dysentery.

- It is caused by eating/drinking food or water contaminated with these amoeba or when hands are not properly sanitized after coming in contact with something contaminated.

- travels to the intestines where it settles and forms cysts that cause symptoms like abdominal pain, fatigue and cramps.

- can lead to severe diarrhea and other digestive problems.

- Entamoeba cells are small, with a single nucleus

Giarda (Giarda lamblia)

- infectious protist that can be transmitted by coming into contact with an infected person or contaminated water

- causes giardiasis, a form of diarrhea.

-invades the small intestine and symptoms include stool, flatulence and accumulation of bad-smelling stomach gas, vomiting, abdominal cramps and bad breath.

- Their life cycle alternates between an actively swimming trophozoite and an infective, resistant cyst.

- has 40 different species names
