Trypanosoma is a genus of kinetoplastids class Kinetoplastidaa monophyletic  group of unicellular parasitic flagellate protozoa. The name is derived from the Greek trypano- borer and soma body because of their corkscrew-like motion.
Trypanosomatidae – definition of Trypanosomatidae by The Free Dictionary
Most trypanosomes are heteroxenous requiring more than one obligatory host to complete life cycle and most are transmitted via a vector. The majority of species are transmitted by blood-feeding invertebratesbut there are different mechanisms among the varying species.
Some, such as Trypanosoma equiperdumare spread by direct contact. In an invertebrate host they are generally found in the intestinebut normally occupy the bloodstream or an intracellular environment in the mammalian host.
Trypanosomes infect a variety of hosts and cause various diseases, including the fzmilia human diseases sleeping sicknesscaused by Trypanosoma bruceiand Chagas disease tfypanosomatidae, caused by Trypanosoma cruzi. The mitochondrial genome of the Trypanosomaas well as of other kinetoplastids, known as the kinetoplastis made up of a highly complex series trgpanosomatidae catenated circles and minicircles and requires a cohort of proteins for organisation during cell division.
InGabriel Valentin found flagellates that today are included in Trypanoplasma in the blood of trout. InDavid Bruce identified the protozoan parasite and the tsetse fly vector of African trypanosomiasis. The monophyly of the genus Trypanosoma is not supported by a number of different methods.
Rather, the American and African trypanosomes constitute distinct clades, implying that the major human disease agents T. Phylogenetic analyses suggest an ancient split into a branch containing all Salivarian trypanosomes and a branch containing all non-Salivarian lineages.
The latter branch splits into a clade containing bird, reptilian and Stercorarian trypanosomes infecting mammals and a clade with a branch of fish trypanosomes and a branch of reptilian or amphibian lineages. Salivarians are trypanosomes of the subgenera of DuttonellaTrypanozoonPycnomonas and Nannomonas.
These trypanosomes are passed to the recipient in the saliva of the tsetse fly Glossina spp. The sub genus Duttonella contains the species T. Stercorians are trypanosomes passed to the recipient in the feces of insects from the subfamily Triatominae most importantly Triatoma infestans. The sub genus Schizotrypanum contains T. The bat species include Trypanosoma cruzi marinkelleiTrypanosoma trypanosomatidaeeTrypanosoma erneyiTrypanosoma livingstonei and Trypanosoma wauwau.
Other related species include Trypanosoma conorhini and Trypanosoma rangeli. The relationships between the species have not been worked out to date. It has been suggested that T. It has been shown that T.
Two different types of trypanosomes exist, and their life cycles are different, the salivarian species and the stercorarian species.
Stercorarian trypanosomes infect insects, most often the triatomid kissing bugby developing in the posterior gut followed by release into the feces and subsequent depositing on the skin of the host.
The organism then penetrates and can disseminate throughout the body. Insects become infected when taking a blood meal. Salivarian trypanosomes develop in the anterior gut of insects, most importantly the Tsetse flyand infective organisms are inoculated into the host by the insect bite before it feeds.
As trypanosomes progress through their life cycle they undergo a series of morphological changes as is typical of trypanosomatids. The life cycle often consists of the trypomastigote form in the vertebrate host and the trypomastigote or promastigote form in the gut of the invertebrate host. Intracellular lifecycle stages are normally found in the amastigote form.
The trypomastigote morphology is unique to species in the genus Trypanosoma. Evidence has been obtained for meiosis in T.
