Protozoa are a diverse group of single-celled organisms that are classified as animals. They are heterotrophic, meaning that they rely on other organisms for their energy and nutrients. Protozoa are found in a variety of environments, including freshwater, marine, and terrestrial ecosystems.
Protozoa are classified into several different groups based on their characteristics and behaviors. Some common groups of protozoa include:
Protozoa are important because they are a major component of many ecosystems, serving as decomposers, herbivores, and predators. They are also important in human health, as some species are parasites that can cause illness in humans and animals.
Human African trypanosomiasis, also known as sleeping sickness, is a parasitic disease transmitted by vectors and caused by Trypanosoma-genus protozoa.

Schistosomiasis also termed snail fever or bilharzia is a disease caused by parasitic flatworms called schistosomes. Infection with Schistosoma mansoni, S. haematobium, and S. japonicum causes illness in humans; less commonly, S. mekongi and S. intercalatum can cause disease.
Fascioliasis is an infectious disease caused by Fasciola parasites, which are flatworms referred to as liver flukes. The adult (mature) flukes are found in the bile ducts and liver of infected people and animals, such as sheep and cattle. In general, fascioliasis is more common in livestock and other animals than in people.
Lymphatic filariasis is a parasitic disease caused by three microscopic, thread-like worms, called Wuchereria bancrofti, Brugia malayi and Brugia timori. These worms infect the lymphatic system and cause Lymphatic filariasis. The adult worm can be found in the human lymph system, this system helps to maintain the body’s fluid balance and fights against infections.
Protozoa carried out their reproduction by asexual and sexual mode of reproduction. The higher group of protozoa follow mainly sexual reproduction. Some protozoa carried out both asexual and sexual reproduction based on the types of the host cells.
The size and shape of protozoa vary based on the types of species. For example, the causative agent of Kala azar, Leishmania donovani has a size range of 1 to 4 micrometers in length, while the Amoeba proteus is 600 micrometers or more in size. Some members of ciliates can reach 2,000 micrometers or 2mm.
Protozoa are unicellular, microscopic, eukaryotic protists which are found in everywhere such as water; soil, on the body of plants and animals. They lack a cell wall and their size ranges from 5 to 250 micrometers.
The term protozoa comes from the Greek word protos and Zoon, which means “first animal”. Protozoa are microscopic single-celled, eukaryotic protists that lack cell walls. The size of protozoa varies from 5 to 250 micrometers. The detailed study of protozoa is known as protozoology.
Leishmaniasis are flagellated protists that cause a group of several human diseases collectively called leishmaniasis. Leishmaniasis also known as kala
Plasmodium is also known as the malaria parasite and is the genus of intracellular parasitic protozoa. They are digenetic parasites because Plasmodium are obligate parasites of insects (such as mosquitoes) and vertebrates.
In this article, we will discuss paramecium definition, kingdom, characters, movement, classes, shape, size, habitat, etc. Paramecium Scientific classification Paramecium
In this article, we will learn about the Habitat, structure, nutrition, characteristics, reproduction, locomotion of the Amoeba cell with diagram.
Protozoa don’t have any cell walls, instead they contain pellicle. The structure of Protozoa is similar to the eukaryotic cells.
