Trypanosoma cruzi and Trypanosoma rangeli: Interplay with Hemolymph Components of Rhodnius prolixus

Journal of Invertebrate Pathology, 1995
Studies were carried out on the course of infection of Trypanosoma cruzi (clone Dm28c) and Trypanosoma rangeli (clone San Agustin) and their interactions with hemolymph components of Rhodnius prolixus. These parasites when inoculated into the hemocoel of adult R. prolixus (i) had different courses of infection (T.

Human urine stimulates in vitro growth of Trypanosoma cruzi and Trypanosoma rangeli

Parasitology Research, 2007
Previous studies conducted in Leishmania led us to test the hypothesis that addition of human urine (HU) to the Liver Infusion Tryptose (LIT) medium would stimulate the in vitro growth of Trypanosoma cruzi and Trypanosoma rangeli strains. Herein, we show that the addition of 3% HU to LIT medium (LIT-HU3) significantly stimulated the growth of all the T.

Search for Trypanosoma Rangeli in Endemic Areas of Trypanosoma Cruzi in Argentina and Brazil

The American Journal of Tropical Medicine and Hygiene, 1977
Because the presence of Trypanosoma rangeli in Argentina and Brazil has not been confirmed, a serach was carried out in man and triatomine insects. Fifty-nine of 207 persons (28.5%) were infected when studied with one or more xenodiagnosis (40 Triatoma infestans/xenodiagnosis); 0.1% to 13% of 7,821 bugs' feces and 4% of 875 dissected midguts showed T ...

Immune Response and Trypanosoma Cruzi Infection in Trypanosoma Rangeli-Immunized Mice

The American Journal of Tropical Medicine and Hygiene, 1991
The capacity of Trypanosoma rangeli antigens to induce immune response in mice was analyzed and the course of the infection was studied in immunized animals challenged with virulent forms of T. cruzi. BALB/c mice were immunized with supernatant of disrupted epimastigotes of T. rangeli and with epimastigotes (EPI) of T. rangeli fixed with glutaraldehyde.

Interspecific differentiation of "Trypanosoma cruzi", "Trypanosoma conorhini" and "Trypanosoma rangeli" by lectins in combination with complement lysis

Acta tropica, 1984
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, 1981
Abstract 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, 1994
Kinetoplast 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.

Sequencing and analysis of chromosomal extremities of Trypanosoma rangeli in comparison with Trypanosoma cruzi lineages

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,

Differentiation of Trypanosoma cruzi and Trypanosoma rangeli of Colombia using minicircle hybridization tests

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.

Antigenic Differentiation of Trypanosoma Cruzi and Trypanosoma Rangeli by means of Monoclonal-Hybridoma Antibodies

The American Journal of Tropical Medicine and Hygiene, 1981
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,
