How does protozoa affect 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..
What protozoa means?
Protozoa (also protozoan, plural protozoans) is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. … Some examples of protozoa are Amoeba, Paramecium, Euglena and Trypanosoma.
Where do protozoa live?
Protozoa are single celled organisms. They come in many different shapes and sizes ranging from an Amoeba which can change its shape to Paramecium with its fixed shape and complex structure. They live in a wide variety of moist habitats including fresh water, marine environments and the soil.
What medicine kills protozoa?
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.
Can protozoa be killed by antibiotics?
“Antimicrobials” are drugs that kill bacteria, fungi, protozoa, or viruses. Antibiotics only kill bacteria. (Antifungals kill fungi; antiprotozoals kill protozoa; antivirals kill viruses.)
What are 5 diseases caused by protozoa?

How can protozoa be controlled?
Prevention (prophylaxis) and treatment of diseases caused by microorganisms has been attempted in four ways:(1) improvements in housing, sanitation and hygiene.(2) control of vectors.(3) development of vaccines.(4) development of drugs.
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.
What is protozoa life cycle?
During its life cycle, a protozoan generally passes through several stages that differ in structure and activity. Trophozoite (Greek for “animal that feeds”) is a general term for the active, feeding, multiplying stage of most protozoa. In parasitic species this is the stage usually associated with pathogenesis.
Which disease is caused by protozoa?
The infectious diseases that are caused by protozoa include Chagas diseases, Human African Tripanosomiasis, and Leishmaniasis, among others.
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.
What do protozoa cause?
Diseases caused by protozoa and helminths, such as malaria and schistosomiasis, are the cause of most parasite related morbidity and mortality, with an estimated 1.1 million combined deaths annually.
