Explanation:
Protozoan infections are parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa. They are usually contracted by either an insect vector or by contact with an infected substance or surface and include organisms that are now classified in the supergroups Excavata, Amoebozoa, SAR, and Archaeplastida.
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.
The species originally termed "protozoa" are not closely related to each other and only have superficial similarities (eukaryotic, unicellular, motile, though with exceptions). The terms "protozoa" (and protist) are usually discouraged in the modern biosciences. However, this terminology is still encountered in medicine. This is partially because of the conservative character of medical classification and partially due to the necessity of making identifications of organisms based upon morphology.
Within the taxonomic classification, the four protist supergroups (Amoebozoa, Excavata, SAR, and Archaeplastida) fall under the Domain Eukarya. Protists are an artificial grouping of over 64,000 different single-celled life forms. This means that it is difficult to define protists due to their extreme differences and uniqueness. Protists are a polyphyletic [(of a group of organisms) derived from more than one common evolutionary ancestor or ancestral group and therefore not suitable for placing in the same taxon][2] a collection of organisms and they are unicellular, which means that they lack the level of tissue organization which is present in more complex eukaryotes. Protists grow in a wide variety of moist habitats and a majority of them are free-living organisms. In these moist environments, plankton and terrestrial forms can also be found. Protists are chemoorganotrophic [organisms which oxidize the chemical bonds in organic compounds as their energy source][3] and are responsible for recycling nitrogen and phosphorus. Parasites also are responsible for causing disease in humans and domesticated animals.
Protozoa are chemoorganotrophic protists and have three different ways of acquiring nutrients. The first method of acquiring nutrients is through saprotrophic nutrition. In saprotrophic nutrition, nutrients are obtained from dead organic matter through enzymatic degradation. The second method of acquiring nutrients is through osmotrophic nutrition. In osmotrophic nutrition, nutrients are obtained through absorbing soluble products. The third method of acquiring nutrients is through holozoic nutrition. In holozoic nutrition, solid nutrients are absorbed through phagocytosis.[1]
Some protozoa are photoautotrophic protists. These protists include strict aerobes, and use photosystems I and II in order to carry out photosynthesis which produces oxygen.[1]
