What Disease Is Caused By A Protozoan?

What does protozoa do to the body?

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..

Why is it difficult to treat protozoan infections?

Protozoa may have complex life-cycles, infections are typically difficult to treat and in most cases prophylactic immunization is ineffective. One redeeming feature is that the organisms are large enough to be seen in stool, other tissue fluids and histologic sections in many cases.

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.

How are protozoan diseases transmitted?

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 can kill protozoa?

Since protozoa are relatively large micro- organisms, they are easier to filter out than bacteria and viruses. Drinking water is disinfected to destroy or inactivate the micro-organisms that are not filtered out. Chlorine is the most common disinfectant in the world.

Are protozoa harmful to humans?

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.

Can protozoa infections be cured?

Protozoan infections can be cured through medications that kill the single-celled parasites that cause the condition. A protozoan infection should be treated as soon as possible. If the condition is allowed to persist, permanent damage to the major organs can occur.

Antimalarial drugs include mefloquine, chloroquine, proguanil with atovaquone and doxycycline. They kill or inhibit the growth of protozoa by affecting different stage of the parasitic life cycle.
