What are two human diseases caused by protists?
For example, protist parasites include the causative agents of malaria, African sleeping sickness, amoebic encephalitis, and waterborne gastroenteritis in humans. Other protist pathogens prey on plants, effecting massive destruction of food crops.
What are 5 diseases caused by protists?
(2012b), Torgerson and Mastroiacovo (2013), World Health Organization (2013).
- 1.1. Malaria. Malaria is the most significant of the protozoan parasites that infect man.
- 1.2. African trypanosomiasis.
- 1.3. Chagas disease.
- 1.4. Leishmaniasis.
- 1.5. Toxoplasmosis.

What protists cause harm to humans?
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.
What are 2 ways that protists can enter the body?
The parasites enter the body through food or water that has been contaminated by feces of infected people or animals. The protozoa attach to the lining of the host’s small intestine, where they prevent the host from fully absorbing nutrients.
What are 3 diseases caused by protists?
Summary
- 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.
Do protists cause human infection?
The pathogenic protists that infect humans are all single-celled organisms, formerly called ‘protozoa’. They are responsible for a range of diseases, including: dysentery (bloody diarrhoea) caused by waterborne protists similar to the amoebae [amm-ee-bee] commonly found in freshwater ponds.
Are diseases caused by protists infectious?
What are two diseases caused by viruses?
Viral Infections Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, Ebola, and COVID-19.
Which protists cause harm to humans quizlet?
Of all the protists, algae cause the most disease in humans. Mutualistic relationships between protists and humans cause harm to human health. Sleeping sickness is a disease caused by a protozoan, which is an animal-like protist. Diseases such as sleeping sickness and Chagas disease are spread to humans by insects.
What diseases caused by protists can be transmitted to humans through drinking water?
Cryptosporidium and Giardia Diseases caused by protozoa that are transmitted by contaminated drinking water are considered waterborne diseases.
What causes human disease?
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.
