Molecular karyotype and chromosomal localization of genes encoding ß-tubulin, cysteine proteinase, hsp 70 and actin in Trypanosoma rangeli

Memorias do Instituto Oswaldo Cruz, 2001
The molecular karyotype of nine Trypanosoma rangeli strains was analyzed by contour-clamped homogeneous electric field electrophoresis, followed by the chromosomal localization of ß-tubulin, cysteine proteinase, 70 kDa heat shock protein (hsp 70) and ...

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. The

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.

Cytochrome c oxidase subunit 1 gene as a DNA barcode for discriminating Trypanosoma cruzi DTUs and closely related species

Parasites & Vectors, 2017
Background The DNA barcoding system using the cytochrome c oxidase subunit 1 mitochondrial gene (cox1 or COI) is highly efficient for discriminating vertebrate and invertebrate species.

Secuenciación del gen de la Sialidasa de Trypanosoma rangeli en aislados con y sin actividad enzimática, de la provincia de Panamá Oeste, República de Panamá

Visión Antataura, 2021
Trypanosoma rangeli es un hemoparásito no patógeno, frecuente en humanos y otros mamíferos. La forma epimastigota de T. rangeli expresan una enzima con actividad de sialidasa (SA), la cual es diferente a la trans-sialidasa encontrada en T. cruzi.
