Protozoal infection results in tissue damage leading to disease. In chronic infections the tissue damage is often due to an immune response to the parasite and/or to host antigens as well as to changes in cytokine profiles. Alternatively, it may be due to toxic protozoal products and/or to mechanical damage.

How do protozoa affect humans?
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 happens if you get protozoa?
Infected individuals may be asymptomatic or have gastrointestinal signs and symptoms, sometimes accompanied by weight loss. Common symptoms, which appear one to three weeks after exposure, include diarrhea, nausea, stomach cramps, gas, greasy stool (because fat absorption is being blocked), and possible dehydration.
How do protozoa cause infection?
Transmission of protozoa that live in a human's intestine to another human typically occurs through a fecal-oral route (for example, contaminated food or water or person-to-person contact).
What disease is caused by protozoa?
Many of the most widespread and fatal human diseases caused by a protozoan infection are African Sleeping Sickness, amoebic dysentery, and malaria. > Two diseases caused by protozoans are Malaria and African Sleeping sickness.
How a protozoa or protozoans can affect our lives?
Protozoan infections are responsible for diseases that affect many different types of organisms, including plants, animals, and some marine life. Many of the most prevalent and deadly human diseases are caused by a protozoan infection, including African Sleeping Sickness, amoebic dysentery, and malaria.
Are all protozoa harmful to humans?
Most protozoa living in the environment are not harmful, except for the disease-producing protozoa that we'll talk about soon. Many types of protozoa are even beneficial in the environment because they help make it more productive. They improve the quality of water by eating bacteria and other particles.
Why are protozoa useful to infection?
Protozoa love moisture, so intestinal infections and other diseases they cause, such as amebiasis and giardiasis, often spread through contaminated water. Some protozoa are parasites, which means that they need to live on or in another organism (like an animal or plant) to survive.
Which protozoa causes sleeping sickness?
Human African trypanosomiasis, also known as sleeping sickness, is a vector-borne parasitic disease. It is caused by infection with protozoan parasites belonging to the genus Trypanosoma.
How do parasites spread from person to person?
Some parasitic infections can be passed from person to person. The most common way this occurs is when food that has been prepared by someone with an infection is eaten. In some cases, the condition can be spread by a tainted blood transfusion or when sharing a needle with someone infected.
Which of the following sets of protozoans cause disease in humans?
Items - Plasmodium, Cuscuta, Trypanosoma. Category - Protozoan parasites.
What are 3 examples of protozoa?
Some examples of protozoa are Amoeba, Paramecium, Euglena and Trypanosoma.
What is protozoal infections?
Protozoal infections are characterized by hyperproliferation of the infectious agent independent of the parasites living intracellularly or extracellularly of their respective host cells. From: Significant Pharmaceuticals Reported in US Patents, 2007.
