Trypanosome infections were sought in 46 non-human primates captured principally in Amazonian Brazil. Twenty-two (47.8%) were infected with four Trypanosoma species: T. cruzi, T. minasense, T. devei and T. rangeli. These preliminary results confirmed the high prevalence and diversity of natural infections with trypanosomes in primates from Brazilian Amazon and were the first formal record of simian infections with trypanosomes in the State of Acre. The presence of T. cruzi-like and T. rangeli… Expand
Molecular Epidemiology of Trypanosomatids and Trypanosoma cruzi in Primates from Peru
The prevalence rate and risk of infection of Trypanosoma cruzi and other trypanosomatids in Peruvian non-human primates (NHPs) in the wild and in different captive conditions are determined. Expand
Trypanosoma cruzi infection in captive Neotropical primates in the Brazilian Amazon
Neotropical primates kept in captivity were infected by T. cruzi in the studied areas and a health management protocol should be put into place to prevent the transmission of infectious agents among captive populations, captive and wild populations, and between NHPs and the technicians who handle these animals.

Trypanosoma cruzi transmission in a captive primate unit, Rio de Janeiro, Brazil.
Examination of 198 primates of CPRJ for infection with the protozoan parasite Trypanosoma cruzi II found that the transmission inside the cages could be attested by the isolation of the T. cruzi from primates born in captivity. Expand

No trypanosomes were visible in blood smears, on wet blood films, or by buffy coat technique, nor were they demonstrable in a subset of C. aethiops individuals that were studied using mouse subinoculation. Expand
Ecological diversity of Trypanosoma cruzi transmission in the Amazon basin. The main scenaries in the Brazilian Amazon.
The ecological diversity of Trypanosoma cruzi transmission in the Brazilian Amazon region is directly interlinked with the parasite's extensive reservoir, composed of 33 species of wild mammalsExpand
High Trypanosoma spp. diversity is maintained by bats and triatomines in Espírito Santo state, Brazil
The ecology of an area in the Atlantic Forest, southeast Brazil, where Chagas disease has been found to occur is re evaluated to show that CD cases can occur without an enzootic cycle near residential areas and show that the host specificity of the Trypanosoma genus should be thoroughly reviewed.

Vector-borne transmission of Trypanosoma cruzi among captive Neotropical primates in a Brazilian zoo
These findings strongly suggest vector-borne T. cruzi transmission within a small-primate unit at ZooB – with vectors, and perhaps also parasites, presumably coming from nearby gallery forest – should be of special importance for captive-breeding programs involving endangered mammals, and would reduce the risk of accidental T.cruzi transmission to keepers and veterinarians.

Infection rates and genotypes of Trypanosoma rangeli and T. cruzi infecting free-ranging Saguinus bicolor (Callitrichidae), a critically endangered primate of the Amazon Rainforest.
This is the first survey of trypanosomiasis in a critically endangered species of tamarin, Saguinus bicolor (Callitrichidae), from the Brazilian Amazon Rainforest, where Trypanosoma cruzi and T. rangeli are commonly infective to non-human primates and several mammals. Expand
Molecular characterization of trypanosomatid infections in wild howler monkeys (Alouatta caraya) in northeastern Argentina
The results demonstrated the presence of T.cruzi and a species closely related to T. minasense in blood samples from free-ranging A. caraya, belonging to different T. cruzi DTUs circulating in these howler monkey populations, and could help evaluate the role of A.Caraya as a reservoir of T., cruzi in regions where Chagas disease is hyper-endemic and where the human-wildlife interface is increasing.

Background: Understanding which non-human primates (NHPs) act as a wild reservoir for blood-borne pathogens will allow us to better understand the ecology of diseases and the role of NHPs in theExpand


The infection rates of trypanosomes in squirrel monkeys at two sites in the Brazilian Amazon.
It is suggested that the validity of T. saimirii needs to be evaluated, as almost all monkeys presenting trypanosomes morphologically indistinguishable from T. rangeli in cultural forms were found through xenodiagnosis and/or haemoculture to be infected by T. minasense. Expand
Trypanosomes and microfilariae in feral owl and squirrel monkeys maintained in research colonies.
A group of 358 owl and squirrel monkeys imported from Colombia, Peru, and Bolivia for the U.S. Agency for International Development Malaria Vaccine Development Program was examined for trypanosomes and microfilariae, finding naturally occurring infections in imported animal models are potential sources of accidental transmission to animal handlers and uninfected laboratory animals.
