Characterization of tubulin genes in Trypanosoma rangeli [PDF]
Molecular and Biochemical Parasitology, 1989 Tubulin genes in Trypanosoma rangeli, the only trypanosome besides T. cruzi to infect humans in America, are organized in homogeneous, alternate alpha and beta gene tandem repeats of 3.8 kb. The basic repeat was cloned, mapped and partially sequenced.

Disease Markers, Volume 2020, Issue 1, 2020., 2020 Chagas disease is a neglected tropical disease caused by the parasite Trypanosoma cruzi. Despite the efforts and distinct methodologies, the search of antigens for diagnosis, vaccine, and drug targets for the disease is still needed. The present study is aimed at identifying possible antigens that could be used for diagnosis, vaccine, and drugs targets

Metalloproteases in Trypanosoma rangeli-infected Rhodnius prolixus [PDF]
Memórias do Instituto Oswaldo Cruz, 1999 Protease activities in the haemolymph and fat body in a bloodsucking insect, Rhodnius prolixus, infected with Trypanosoma rangeli, were investigated. After SDS-polyacrylamide gel electrophoresis containing gelatin as substrate, analysis of zymograms performed on samples of different tissues of controls and insects inoculated or orally infected with ...

Karyotype variability in Trypanosoma rangeli
Parasitology, 1996 SUMMARYThe molecular karyotypes of several different protozoan parasites show high intra-species variation, including different kinetoplastids such as Trypanosoma brucei, Trypanosoma cruzi and Leishmania ssp. In this study, the molecular karyotype of Trypanosoma rangeli was examined.

Trypanosoma rangeli (Tejera, 1920): observations upon pleomorphism [PDF]
Memórias do Instituto Oswaldo Cruz, 1992 Meta-trypomastigotes of Trypanosoma rangeli Tejera, 1920, harvested from LIT medium, were inoculated i.p. or s.c. into 6, 16, and 26 g NMRI mice, these representing increasing degrees of immunological maturity. In all cases, similar pleomorphic patterns were observed.

Trypanosoma rangeli sialidase lacks trans-sialidase activity [PDF]
Molecular and Biochemical Parasitology, 1993 Extracts and tissue culture supernatants of axenic forms of T. rangeli were assayed for the presence of sialidase and trans-sialidase activities. Using sialyl(alpha 2-3)lactose, sialyl(alpha 2-6)lactose, poly(alpha 2-8)N-acetylneuraminic acid, fetuin and 4-methylumbelliferyl-N-acetylneuraminic acid as sialic acid donors, and lactose as a sialic acid ...
