Vaccination with Trypanosoma rangeli modulates the profiles of immunoglobulins and IL-6 at local and systemic levels in the early phase of Trypanosoma cruzi experimental infection

Memorias do Instituto Oswaldo Cruz, 2011
In America, there are two species of Trypanosoma that can infect humans: Trypanosoma cruzi, which is responsible for Chagas disease and Trypanosoma rangeli, which is not pathogenic. We have developed a model of vaccination in mice with T.

Genetic Structure and Expression of the Surface Glycoprotein GP82, the Main Adhesin of Trypanosoma cruzi Metacyclic Trypomastigotes

The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013
T. cruzi improves the likelihood of invading or adapting to the host through its capacity to present a large repertoire of surface molecules. The metacyclic stage‐specific surface glycoprotein GP82 has been implicated in host cell invasion. GP82 is encoded by multiple genes from the trans‐sialidase superfamily.

Effects of Sheep and Mouse Urine on the Growth Pattern of Leishmania major Promastigotes

BioMed Research International, Volume 2013, Issue 1, 2013., 2013
The protozoan parasites of the genus Leishmania are the causative agents of different clinical diseases. Fetal calf serum (FCS) is the main part and the most expensive ingredient of the Leishmania culture media. Here, the efficacies of different concentrations (1%, 2.5%, 5%, and 10%) of the filtered and autoclaved sheep and mouse urine were evaluated ...

Studies on Trypanosoma rangeli Tejera 1920. VII - Its effect on the survival of infected triatomine bugs

Memorias do Instituto Oswaldo Cruz, 1984
The pathological effects of Trypanosoma rangeli on Rhodnius prolixus and R. robustus, and the relation of mortality to infection, were studied under laboratory conditions. Frequent observations revealed that when the first instar nymphs of R.

International meeting: New diagnostic tests are urgently needed to treat patients with Chagas disease. [PDF]

, 2008
Trypanosoma cruzi infection is often not detected early on or actively diagnosed, partly because most infected individuals are either asymptomatic or oligosymptomatic.

Genes for cysteine proteinases fromTrypanosoma rangeli [PDF]

FEMS Microbiology Letters, 1995
PCR amplification of genomic DNA from the American trypanosome, Trypanosoma rangeli, using as primers oligonucleotides derived from the gene of cruzipain, the major cysteine proteinase (CP) from Trypanosoma cruzi, allowed the production of a probe which was used to obtain three clones encoding a CP with 70% overall identity with cruzipain.

Successional and native forests predict the occurrence and infection status of Chagas disease vectors in Panama

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Findings here show that successional forest predicts greater kissing bug infestation risk in palm trees, whereas native forest predicts lower kissing bug occurrence but greater infection with T. cruzi. These insights can guide land use planning towards vegetation management practices that help minimize T. cruzi transmission risks for rural communities.

First Report of Trypanosoma sp. in Spectacled Caiman (Caiman crocodilus): Morphological and Phylogenetic Relationships

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
In Crocodylidae family three trypanosomes species were described, T. grayi in African crocodilian and T. cecili and Trypanosoma sp. in Caimans species from Brazil. T. grayi was transmitted by tsetse flies and the vector of Brazilian caimans trypanosomes is unknown.

TcI isolates of Trypanosoma cruzi exploit the antioxidant network for enhanced intracellular survival in macrophages and virulence in mice [PDF]

, 2016
Trypanosoma cruzi species is categorized into six discrete typing units (TcI to TcVI) of which TcI is most abundantly noted in the sylvatic transmission cycle and considered the major cause of human disease. In our study, the TcI strains Colombiana (COL),

Trypanosoma rangeli expresses a β-galactofuranosyl transferase

Experimental Parasitology, 2012
Glycoconjugates play essential roles in cell recognition, infectivity and survival of protozoan parasites within their insect vectors and mammalian hosts. β-galactofuranose is a component of several glycoconjugates in many organisms, including a variety of trypanosomatids, but is absent in mammalian and African trypanosomes.
