What Are Three Diseases Caused By Protists?

How are protists ecologically important?

Protists function at several levels of the ecological food web: as primary producers, as direct food sources, and as decomposers.

In addition, many protists are parasites of plants and animals and can cause deadly human diseases or destroy valuable crops..

Do protists make their own food?

Protists are mostly one-celled organisms. Some make their own food, but most take in or absorb food. Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms.

What disease is caused by a protist?

Most protist diseases in humans are caused by protozoa. Protozoa make humans sick when they become human parasites. Trypanosoma protozoa cause Chagas disease and sleeping sickness. Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.

What are 2 diseases caused by protozoans?

The infectious diseases that are caused by protozoa include Chagas diseases, Human African Tripanosomiasis, and Leishmaniasis, among others. Chagas disease is a tropical parasitic disease caused by the Protist, Trypanosoma cruzi which spreads through insects like “kissing bugs”.

What are three diseases caused by protozoa?

What Diseases Do They Cause?Common infectious diseases caused by protozoans include malaria, giardia, and toxoplasmosis. … Human African trypanosomiasis is caused by Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense. … Treatment options just depend on what protozoa are infecting you.More items…

Is protists good or bad?

But, like any other organism, they can also inflict harm, particularly to humans. Most harmful protists are classified as animal-like protists that act as parasites, or organisms that benefit from causing harm to other organisms. … African sleeping sickness is caused by trypanosoma protists.

How do protists affect humans?

Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. … For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis.

What are the harmful effects of protist?

Some severe diseases of humans are caused by protists, primarily blood parasites. Malaria, trypanosomiasis (e.g., African sleeping sickness), leishmaniasis, toxoplasmosis, and amoebic dysentery are debilitating or fatal afflictions.

Where can protists be found?

Most protists can be found in moist and wet areas. They can also be found in tree trunks and other organisms.

How do protists survive?

There are many plant-like protists, such as algae, that get their energy from sunlight through photosynthesis. Some of the fungus-like protists, such as the slime molds (Figure below), decompose decaying matter. The animal-like protists must “eat” or ingest food. Some animal-like protists use their “tails” to eat.

Why is it important to study protists?

The slime molds are important to ecosystems because they are decomposers, which release vital nutrients back into the environment. You could say life on Earth depends on the protists because they supply us with oxygen, are critical organisms in food chains, and recycle important nutrients for other life forms to use.

How are protist diseases treated?

Antibiotics don’t work exclusively against bacteria: some ‘broad-spectrum’ ones are also effective against protists. Malaria is a disease caused by protozoa that are carried by certain mosquitoes. Antibiotics, such as doxycycline, can be used in both treatment and prevention of malaria.
