Four-day-old epimastigote culture forms of Trypanosoma cruzi, Trypanosoma rangeli and Trypanosoma conorhini were tested with 21 lectins. Furthermore T. conorhini was incubated with the following sera: rat, Wistar HAN, germ free; normal fresh hen, rat and human serum. T.

Trypanosoma cruzi and Trypanosoma rangeli: Glutamate dehydrogenases and proteolytic activities
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1981Abstract 1. 1. Trypanosoma (Herpetosoma) rangeli contains proteolytic activity with azocasein, casein and BAPA as substrates, and aminopeptidase activity with Arg-BNA as substrate. The respective pH optima were 5.5, 7.0, 8.5 and 7.0. 2. 2. The effect of the protease inhibitors PMSF, TLCK and trasylol was studied.

Characterization of kinetoplast DNA minicircles in Trypanosoma rangeli
Molecular and Biochemical Parasitology, 1994Kinetoplast DNA, the mitochondrial DNA of kinetoplastid protozoans, is a network of interlocked minicircles and maxicircles. We analyzed the sequence organization of minicircle DNAs in the El Tocuyo strain and the San Augustin clone B6 of Trypanosoma rangeli.

With the aim of identifying and differentiating Trypanosoma cruzi from Trypanosoma rangeli, culture epimastigotes from 30 Honduran trypanosomatid isolates were analyzed by susceptibility to complement lysis, reactivity to lectins, reactivity to monoclonal antibodies specific for T. cruzi, and isoenzymatic electrophoretic patterns.

Parasitology Research, 2010
The aim of this study was to investigate the genetic variability of sequences present in the chromosome ends of Trypanosoma rangeli strains defined by the presence (+) or absence (-) of KP1 minicircles, and to compare the mean terminal restriction fragment (TRF) lengths to those of Trypanosoma cruzi populations representative of groups TcI, TcII, TcIV,

Diagnostic Microbiology and Infectious Disease, 2010
Although Trypanosoma rangeli is harmless for humans, it is a serious problem since it may be confused with diagnosis of Trypanosoma cruzi, the etiologic agent of Chagas disease. Both parasites overlap geographically, share antigenic protein, and are able to infect the same Triatominae vector and vertebrate host, including human.

Vaccination with Trypanosoma rangeli induces resistance of guinea pigs to virulent Trypanosoma cruzi
Veterinary Immunology and Immunopathology, 2014Chagas' disease, endemic in Latin America, is spread in natural environments through animal reservoirs, including marsupials, mice and guinea pigs. Farms breeding guinea pigs for food are located in some Latin-American countries with consequent risk of digestive infection.

Trypanosoma rangeli: Effect on excretion in Rhodnius prolixus
Journal of Invertebrate Pathology, 1971Abstract Excretion is severely reduced in Rhodnius prolixus infected with Trypanosoma rangeli , particularly in those bugs with hemocoelic infections. Several factors probably contribute to this reduction: tissue damage, lack of diuretic hormone or the presence of a chemical inhibitor in the hemolymph, and changes in its osmotic pressure.

Sera from Balb/c mice, hyperimmunized with ruptured epimastigotes of either Trypanosoma cruzi or Trypanosoma rangeli, lacked species-specificity when assayed for antibodies by indirect immunofluorescent microscopy and by the enzyme-linked immunosorbent assay. However, when plasma cells from those mice were fused with syngeneic mouse plasmacytoma cells,

Histology of Rhodnius prolixus infected with Trypanosoma rangeli
Journal of Invertebrate Pathology, 1971Abstract Intracellular stages of Trypanosoma rangeli develop in most tissues of infected Rhodnius prolixus , but they show a predilection for gut musculature, fat body, epidermis, and salivary glands. Heavy hemocoelic infections often result in severe nerve damage and hypertrophy of tracheal cells, which finally rupture and release flagellates. T.
