The kinetoplastids are a group of flagellate protozoa, including a number of parasites responsible for serious diseases in humans and other animals, as well as various forms found in soil and aquatic environments. Trypanosoma cruzi is a species of parasitic Euglenoid Trypanosomes The species causes the Trypanosomiasis diseases Animals Plants fungi, and Protists are eukaryotes (juːˈkærɪɒt or -oʊt Organisms whose cells are organized into complex The excavates are a major assemblage of Protists often known as Excavata. The Euglenozoa are a large group of Flagellate protozoa They include a variety of common free-living species as well as a few important parasites some of which infect humans The kinetoplastids are a group of Flagellate Protozoa, including a number of Parasites responsible for serious diseases in humans and other animals as well Trypanosomes are a group of Kinetoplastid protozoa distinguished by having only a single Flagellum. Flagellates are cells with one or more whip-like organelles called flagella. Protozoa (in Greek πρῶτον proton "first" and ζῷα zoia "animals" are unicellular Eukaryotes (singular Parasitism is a type of symbiotic relationship between Organisms of different Species. They are included in the Euglenozoa, and are distinguished from other such forms mainly by the presence of a kinetoplast, a DNA-containing granule located within the single mitochondrion and associated with the flagellar bases. The Euglenozoa are a large group of Flagellate protozoa They include a variety of common free-living species as well as a few important parasites some of which infect humans A Kinetoplast is a disk-shaped mass of circular DNAs inside a large Mitochondrion that contains many copies of the Mitochondrial genome. Deoxyribonucleic acid ( DNA) is a Nucleic acid that contains the genetic instructions used in the development and functioning of all known In Cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed Organelle found in most eukaryotic cells.
Most forms have a leading and trailing flagellum, the latter of which may or may not be attached to the side of the cell and is often used to glide along or attach to surfaces. The cytostome is often bordered by a ridge or rostrum. A cytostome or cell mouth is a part of a cell specialized for Phagocytosis, usually in the form of a Microtubule -supported funnel or groove Bodo is a typical genus, including various common free-living species which feed on bacteria. Bodo is a genus of Flagellate Protozoan They are free-living relatives of the parasitic Trypanosomes The most well-known species is The Bacteria ( singular: bacterium) are a large group of unicellular Microorganisms Typically a few Micrometres in length bacteria have Others include Cryptobia and Trypanoplasma. There is also one family of kinetoplastids, the trypanosomes, which only have a single emergent flagellum, including several genera which are exclusively parasitic. Trypanosomes are a group of Kinetoplastid protozoa distinguished by having only a single Flagellum.
Trypanosomes have reduced or absent cytostomes, feeding entirely through absorption, and smaller kinetoplasts than other forms. They typically have complex life-cycles involving more than one host, and go through various morphological stages. The most distinctive of these are the Trypomastigote stages, where the flagellum runs along the length of the cell and is connected to it forming an undulating membrane. Diseases caused by trypanosomes include sleeping sickness and Chagas disease, from species of Trypanosoma, and leishmaniasis, from species of Leishmania. Sleeping sickness or human African trypanosomiasis is a Parasitic Disease of people and animals caused by Protozoa of species Chagas disease (doença de Chagas enfermedad de Chagas mal de Chagas in both languages also called American trypanosomiasis) is a tropical Parasitic Trypanosoma are of the class kinetoplastida a Monophyletic group of unicellular parasitic Protozoa. Leishmaniasis is a Disease caused by Protozoan Parasites that belong to the genus Leishmania and is transmitted by the bite of certain Leishmania is a Genus of Trypanosome Protozoa, and is the Parasite responsible for the disease Leishmaniasis.
The kinetoplastids were first defined by Honigberg in 1961 as the flagellate order Kinetoplastida[1]. Year 1961 ( MCMLXI) was a Common year starting on Sunday (link will display full calendar of the Gregorian calendar. They are traditionally divided into the biflagellate Bodonidae and uniflagellate Trypanosomatidae, which may be promoted to orders; the former appears to be paraphyletic to the latter.
