where is trypanosoma cruzi found in the body
Trypanosoma cruzi 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.
Psilocybe semilanceata The mushroom also has a widespread distribution in North America. In Canada it has been collected from British Columbia, New Brunswick, Newfoundland, Nova Scotia, Prince Edward Island, Ontario and Quebec.[45] In the United States, it is most common in the Pacific Northwest, west of the Cascade Mountains, where it fruits abundantly in autumn and early winter; fruiting has also been reported to occur infrequently during spring months.[22] Charles Horton Peck reported the mushroom to occur in New York in the early 20th century, and consequently, much literature published since then has reported the species to be present in the eastern United States. Gaston Guzman later examined Peck's herbarium specimen, and in his comprehensive 1983 monograph on Psilocybe, concluded that Peck had misidentified it with the species now known as Panaeolina foenisecii.[46][47] P.Â semilanceata is much less common in South America,[46] where it has been recorded in Chile.[45] It is also known in Australia (where it may be an introduced species)[26] and New Zealand, where it grows in high-altitude grasslands.[48] In 2000, it was reported from Golaghat, in the Indian state of Assam.[49]
