Experimental Trypanosoma rangeli infection in a murine model.

Revista de biologia tropical, 1998
Trypanosoma rangeli experimental murine infections were peñormed in order to study parasitemias and anti-parasite antibody levels. Three groups of miee were used: a) miee infected with metatrypomastigotes derived from infected bugs; b) miee which received four reinoculations of metatrypomastigotes and c) miee immunosuppressed with cyclophosphamide.

A simplified method for sample collection and DNA isolation for polymerase chain reaction detection of Trypanosoma rangeli and Trypanosoma cruzi in triatomine vectors

Memorias do Instituto Oswaldo Cruz, 2000
Due to the overlapping distribution of Trypanosoma rangeli and T. cruzi in Central and South America, sharing several reservoirs and triatomine vectors, we herein describe a simple method to collect triatomine feces and hemolymph in filter paper for ...

Phylogenetic and syntenic data support a single horizontal transference to a Trypanosoma ancestor of a prokaryotic proline racemase implicated in parasite evasion from host defences

Parasites & Vectors, 2015
Background Proline racemase (PRAC) enzymes of Trypanosoma cruzi (TcPRAC), the agent of Chagas disease, and Trypanosoma vivax (TvPRAC), the agent of livestock trypanosomosis, have been implicated in the B-cells polyclonal activation contributing to ...

Behavioral fever response in Rhodnius prolixus (Reduviidae: Triatominae) to intracoelomic inoculation of Trypanosoma cruzi

Revista da Sociedade Brasileira de Medicina Tropical
: INTRODUCTION: Behavioral fever is a response to infections with microorganisms observed in some poikilothermic animals. Rhodnius prolixus is involved in the transmission of two parasites: Trypanosoma cruzi (pathogenic for humans and transmitted in ...
