How do humans 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..
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.
How is protozoan infection diagnosed?
Microscopy. The most unequivocally diagnosis of protozoan infections is by demonstration of the organism in the blood, bone marrow, cerebrospinal fluid, faeces or urine. The simplest method of microscopic examination is the examination of smears.
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.
How do protozoa infect humans?
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).
How do you know if you have parasites in your body?
Symptomsabdominal pain.diarrhea, nausea, or vomiting.gas/bloating.fatigue.unexplained weight loss.abdominal pain or tenderness.
What can protozoa cause?
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.
What is protozoa infection?
Protozoal infections are characterized by hyperproliferation of the infectious agent independent of the parasites living intracellularly or extracellularly of their respective host cells.
What are 5 diseases caused by protozoa?

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.)
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.
How are protozoa harmful?
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 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 are the symptoms of a protozoan infection?
The most common symptoms associated with infection include abdominal discomfort, diarrhea, flatulence, and sometimes fever and bloating.
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.
