Protozoa are single-celled animals too small to see with the naked eye they feed by taking in other organisms such as bacteria and algae or organic particles such as animal or plant debris. Super-powered protists protozoa are also known as protists these are the bad boys of the microbe world (bad meaning advanced) protists are eukaryotes with special structures that may be the base organisms of multicellular organisms. The protozoa were all thought to be single celled eukaryotes the concept was popular for much of the 20th century, but it has become clear that some are relatives of animals and fungi, others have closer relationships with algae than with other protozoa, and that protozoa are not closely related. While the term protozoa is commonly used, it has little basis in evolutionary history, or phylogeny, of these organisms taxonomic systems try to assign organisms to a monophyletic group, that is, one that includes an ancestor and all of its descendants.
Spore-forming protozoa: all of these organisms may be common worldwide, and their frequency may be related to the adequacy of sanitation in general, the infections are more common in developing countries.

Protozoa are single-celled eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy they are often. Spirochaete bacteria are another group that is commonly found in pond water unlike cyanobacteria, which have numerous hair-like structures that make them fast movers protozoa their cells also have membrane bound cell organelles. Rotifers are a relatively common microorganism that can be found pretty much everywhere in the world and they're also one of the most common drinking water contaminants, despite growing as large as 1mm at times (which is hardly microscopic—you can see that with your naked eye.
Protozoa are a diverse group of microorganisms most are free-living organisms that can reside in fresh water and pose no risk to human health some enteric protozoa, such as giardia and cryptosporidium, are pathogenic and have been associated with drinking water related outbreaks they may be found. The protozoa are considered to be a subkingdom of the kingdom protista, although in the classical system they were placed in the kingdom animalia more than 50,000 species have been described, most of which are free-living organisms protozoa are found in almost every possible habitat.

Protozoa are eukaryotic microorganisms although they are often studied in zoology courses, they are considered part of the microbial world because they are unicellular and microscopic protozoa are notable for their ability to move independently, a characteristic found in the majority of species. While the term protozoa is commonly used, it has little basis in evolutionary history, or phylogeny, of these organisms protozoa are ubiquitous (found. Found in freshwater, marine, and moist terrestrial habitats many serve as food for other organisms in aquatic habitats called zooplankton (protozoans) or phytoplankton (algae) all reproduce asexually but a few can also reproduce sexually, exchanging genetic information.
Common infectious diseases caused by protozoans include malaria, giardia, and toxoplasmosis these infections are found in very different parts of the body — malaria infections start in the blood, giardia starts in the gut, and toxoplasmosis can be found in lymph nodes, the eye, and also worrisomely the brain. Overview of intestinal protozoan and microsporidia infections multiple pathogenic parasites and nonpathogenic commensal organisms may be present in the intestine. Organisms that fit the contemporary definition of a protozoan are found in all major groups of protists that are recognized by protistologists, reflecting the paraphyletic nature of protozoans.
