<Tr> <Th_colspan="2"> Binomial name </Th> </Tr> <Tr> <Td_colspan="2"> Trypanosoma cruzi Chagas, 1909 </Td> </Tr> <P> Trypanosoma cruzi is a species of parasitic euglenoids . Amongst the protozoa, the trypanosomes characteristically bore tissue in another organism and feed on blood (primarily) and also lymph . This behaviour causes disease or the likelihood of disease that varies with the organism: for example, trypanosomiasis in humans (Chagas disease in South America), dourine and surra in horses, and a brucellosis - like disease in cattle . Parasites need a host body and the haematophagous insect triatomine (descriptions "assassin bug", "cone - nose bug", and "kissing bug") is the major vector in accord with a mechanism of infection . The triatomine likes the nests of vertebrate animals for shelter, where it bites and sucks blood for food . Individual triatomines infected with protozoa from other contact with animals transmit trypanosomes when the triatomine deposits its faeces on the host's skin surface and then bites . Penetration of the infected faeces is further facilitated by the scratching of the bite area by the human or animal host . </P> <P> The Trypanosoma cruzi life cycle starts in an animal reservoir, usually mammals, wild or domestic, including humans . A triatomine bug serves as the vector . While taking a blood meal, it ingests T. cruzi . In the triatomine bug (Triatoma infestans) the parasite goes into the epimastigote stage, making it possible to reproduce . After reproducing through binary fission, the epimastigotes move onto the rectal cell wall, where they become infectious . Infectious T. cruzi are called metacyclic trypomastigotes . When the triatomine bug subsequently takes a blood meal from a human, it defecates . The trypomastigotes are in the feces and are capable of swimming into the host's cells using flagella, a characteristic swimming tail dominant in the Euglenoid class of protists . </P>
