Simple protozoa, in high numbers, can cause muscle paralysis and respiratory failure in humans, possibly leading to death. Types of Protozoa. There are many phyla in the Domain Protista. While this represents a wide variety of them, it is not close to all of them.
Protozoa (also protozoan, plural protozoans) is an informal term for single-celled eukaryotes, either free-living or parasitic, which feed on organic matter such as other microorganisms or organic tissues and debris. Historically, the protozoa were regarded as "one-celled animals", because they often possess animal-like behaviors, such as motility and predation, and lack a cell wall, as ...
This protozoan is of 4 types like plasmodium vivox, P. falciparum, P. malaria, P. ovale. Of them the last one is deadly. Image By Jfbranch14/commons.wikimedia.org. The protozoa in the humans reside in the red blood cells. It eats up hemoglobin and converts it into a poisonous substance Haemozoin. When the RBC breaks down, the hemozoin is ...
Protozoa that live in the blood or tissue of humans are transmitted to other humans by an arthropod vector (for example, through the bite of a mosquito or sand fly). Entamoeba histolytica is a protozoan. A microscope is necessary to view this parasite. Credit CDC.
The protozoa group comprises more than 65,000 species. All the protozoan species belong to the kingdom Protista. Many kinds of protozoa are symbionts. Some of the protozoan species are parasites and some are predators of bacteria and algae. Some examples of protozoans are dinoflagellates, amoebas, paramecia, and plasmodium.
Parasites provide an opportunity for the transfer of genetic material between species, facilitating evolutionary change. Many parasites require multiple hosts of the different species to complete their life cycles and rely on predator–prey or other stable ecological interactions to get from one host to another.
Different kinds of Protozoa. STUDY. PLAY. Sporozoa. Sporozoa include the intracellular parasites of the genus Plasmodium. These cause malaria, an illness characterised by recurrent bouts of fever and sweating. It is spread by mosquitoes of the genus Anopheles. Flagellate protozoa.

Parasites are organisms that depend on other biological hosts for deriving nutrition, shelter, and other benefits, while harming the host. There are many types of parasites that infest humans as well as animals.
