What is the most common protozoan infection?
Many of the most prevalent and deadly human diseases are caused by a protozoan infection, including African Sleeping Sickness, amoebic dysentery, and malaria..
How do you treat protozoa infections?
The primary therapy of choice for E. histolytica is metronidazole. It can be administered PO or IV at 250–750 mg every 8–12 hours. Other treatment modalities that can be used are diloxanide, an amebicide at the dose of 500 mg orally three times daily for 10 days.
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 is the most common parasitic infection?
Some people think of parasitic infections, like malaria, as occurring only in developing countries or in tropical areas, but parasitic infections exist in North America as well. The most common ones found in North America include Giardia infections (through contaminated water) and toxoplasmosis (spread by cats).
Can protozoa be treated with antibiotics?
“Antimicrobials” are drugs that kill bacteria, fungi, protozoa, or viruses. Antibiotics only kill bacteria. (Antifungals kill fungi; antiprotozoals kill protozoa; antivirals kill viruses.)
Where do protozoan parasites come from?
They can be found in ponds, streams, rivers, swamps and in most soil. Even the most polluted water contains some species of protozoa. Protozoa have a life process similar to animals because they can obtain their food by taking up food particles from the environment rather than making their own food by photosynthesis.
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.
Which disease is caused by protozoa?
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.
Is a protozoan a virus?
Protozoa are single celled organisms. Most protozoa do not cause infections, but a few do. Malaria, dysentery, African sleeping sickness are caused by different species of protozoa.
What are the symptoms of a protozoan infection?
The most common symptoms associated with infection include abdominal discomfort, diarrhea, flatulence, and sometimes fever and bloating.
Can protozoa make you sick?
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 5 diseases caused by protozoa?

What are 2 diseases caused by protozoans?
Common infectious diseases caused by protozoans include:Malaria.Giardia.Toxoplasmosis.
How can we get rid of protozoa?
The first line of treatment is typically oral rehydration therapy. Medications are sometimes used to treat the diarrhea. The broad-range anti-parasitic drug nitazoxanide can be used to treat cryptosporidiosis. Other anti-parasitic drugs that can be used include azithromycin and paromomycin.
