Abstract: Trypanosoma cruzi (Kinetoplastea: Trypanosomatidae) infects all tissues of its hosts, which along with humans, include hundreds of mammalian species in the Americas. The epidemiology of T. cruzi has been changing in that currently the majority of the cases and/or outbreaks of Chagas disease occur by the ingestion of comestibles contaminated by T. cruzi metacyclic forms. These cases/outbreaks occur in distinct regional scenarios, mainly in the Amazon biome and are related to the local interaction mode of humans… Show more

“…As recently described [9,10], the association of T. cruzi lineages with hosts, biomes or habitats is complex and not fixed. Infecting lineage composition may fluctuate within mammalian populations over time if there is varying exposure and transmission efficiency.…”

“…Although DTUs TcIII and TcIV are widely distributed and may infect a wide variety of mammals, they appear to occur at significantly lower rates, most likely because they are maintained in very low parasitemia in nature, which hampers their detection [23,32]. Although classically associated to armadillos [38,39], T. cruzi TcIII has also proved to be able to infect wild rodents, marsupials, carnivores, and artiodactyls, as well domestic dogs [5,23]. Previous long-term carnivore monitoring studies in the same area (Limoeiro Region, Cumari) registered two hoary foxes (Lycalopex vetulus) that were infected by T. cruzi DTU TcIII [22,23], which indicate the putative share of these DTUs between small mammals and canids of the same area.…”

“…In humans, T. cruzi is the etiological agent of Chagas disease and six Discrete Typing Units (DTU) are currently recognized in this parasite: TcI to TcVI, besides Tcbat, a seventh DTU described in bats [3,4]. Despite proposed attempts to correlate T. cruzi subpopulations with host species, geographic distribution, and/or human disease, it has not yet been possible to detect any unequal association [5].Leishmania spp. currently comprises more than 30 species, some of which are responsible for distinct clinical forms of human leishmaniasis as zoonotic diseases with high public health impact [6,7].…”
