Trypanosoma cruzi: adaptation to its vectors and its hosts
TLDR
Biological plasticity, which is probably the result of the considerable heterogeneity of the taxon, exemplifies a successful adaptation of a parasite resulting in distinct outcomes of infection and a complex epidemiological pattern. Expand
Enzootiology of Trypanosoma evansi in Pantanal, Brazil.
TLDR
The highest prevalence of T. evansi infection was recorded in horses, although no neurological signs in infected horses were observed, and Diagnosis through standard parasitological tests and IFAT should be used with caution since they may overlook comprovedly infected horses. Expand
Molecular epidemiology of American trypanosomiasis in Brazil based on dimorphisms of rRNA and mini-exon gene sequences.
TLDR
Molecular typing of human parasite isolates from three well-characterised endemic regions of Chagas disease and from Amazonas State, where T. cruzi is enzootic, suggests that in some endemic areas in Brazil there is a preferential linkage between both cycles mediated by lineage-1 stocks. Expand
Trypanosoma cruzi infection in wild mammals of the National Park 'Serra da Capivara' and its surroundings (Piaui, Brazil), an area endemic for Chagas disease.
TLDR
Serum prevalence among dogs suggests that they may be involved in the maintenance of the parasite in the peridomestic environment, in contrast to goats, which are not apparently of any epidemiological importance. Expand
The multiple and complex and changeable scenarios of the Trypanosoma cruzi transmission cycle in the sylvatic environment.
TLDR
The results demonstrate the complexity of the Trypanosoma cruzi reservoir system and its transmission strategies, indicating that there is considerably more to be learned regarding ecology of T. cruzi. Expand
Wild and synanthropic reservoirs of Leishmania species in the Americas
Graphical Abstract
Can wild Triatoma infestans foci in Bolivia jeopardize Chagas disease control efforts?
TLDR
Wild populations of Triatoma infestans are much more widespread throughout Bolivia than previously thought, and it is important to find out whether these silvatic populations could jeopardize control efforts in Bolivia, and to investigate their possible occurrence in neighboring regions of Paraguay and Argentina. Expand
Trypanosoma cruzi transmission cycle among wild and domestic mammals in three areas of orally transmitted Chagas disease outbreaks.
TLDR
T. cruzi infection in wild and domestic mammals from three orally acquired Chagas disease outbreak areas in Brazil shows a panzootic scenery, and domestic animals showed a high seroprevalence and should be considered sentinels in surveillance programs. Expand
Trypanosoma cruzi Infection in Neotropical Wild Carnivores (Mammalia: Carnivora): At the Top of the T. cruzi Transmission Chain
TLDR
Findings corroborate the coati can be a bioaccumulator of T. cruzi Discrete Typing Units (DTU) and may act as a transmission hub, a connection point joining sylvatic transmission cycles within terrestrial and arboreal mammals and vectors. Expand
Canine visceral leishmaniasis in Barra de Guaratiba, Rio de Janeiro, Brazil: assessment of risk factors.
TLDR
The presence of Lutzomyia longipalpis in the peridomestic environment indicates the possibility of appearence of new human cases and the data suggest the presence of a sylvatic enzootic cycle at this locality. Expand
