Innate trypanolytic factors in triatomine hemolymph against Trypanosoma rangeli and T. cruzi: a comparative study in eight Chagas disease vectors

, 2020
There is limited information about the innate immunity of triatomines against Trypanosoma rangeli, an infectious, non-pathogenic human parasite, and T. cruzi, the causative agent of Chagas’ disease. This study aimed at addressing this gap by studying the

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.

Unravelling the biochemical aspects of the interaction between ticks and Leishmania using a tick cell line

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 350-359, June 2026.
Leishmania infantum propagated in IDE8 tick cell line in vitro. L. infantum reduces tick cell viability and induces reactive oxygen species production. Lipidic profile of IDE8 tick cell line is altered during Leishmania infection. Abstract Leishmaniasis comprises a group of vector‐borne neglected tropical diseases caused by species of the obligatory ...

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 ...

Trypanosoma rangeli is phylogenetically closer to Old World trypanosomes than to Trypanosoma cruzi.

International Journal of Parasitology, 2018
Trypanosoma rangeli and Trypanosoma cruzi are generalist trypanosomes sharing a wide range of mammalian hosts; they are transmitted by triatomine bugs, and are the only trypanosomes infecting humans in the Neotropics.

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.
