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 infections are 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.

Plasmodium protozoa are also known to cause Malaria. Mosquitos become carriers through inhabiting contaminated water.

What is protozoa in simple words?

They are often grouped in the kingdom Protista together with the plant-like algae and fungus-like water molds and slime molds.

What medicine kills protozoa?

Antiprotozoal drug, any agent that kills or inhibits the growth of organisms known as protozoans. Protozoans cause a variety of diseases, including malaria and Chagas’ disease.
