Species-specific markers for the differential diagnosis of Trypanosoma cruzi and Trypanosoma rangeli and polymorphisms detection in Trypanosoma rangeli

Parasitology Research, 2014
Trypanosoma cruzi and Trypanosoma rangeli are kinetoplastid parasites which are able to infect humans in Central and South America. Misdiagnosis between these trypanosomes can be avoided by targeting barcoding sequences or genes of each organism.

Neuraminidase activity in Trypanosoma rangeli

Molecular and Biochemical Parasitology, 1985
Supernatants of cultures and extracts of Trypanosoma rangeli readily release N-acetyl neuraminic acid from a variety of substrates. The activity in both supernatant and cell extract is precipitated between 30 and 50% ethanol, and between 40 and 70% ammonium sulfate.

Antigenic Significance of a Trypanosoma rangeli Sialidase

The Journal of Parasitology, 2002
The Trypanosoma rangeli-secreted sialidase was purified by bovine submaxillary gland mucin-sepharose affinity chromatography. In immunoblotting analysis, antibodies raised against this molecule recognized polypeptides of 73 kDa in T. rangeli medium supernatant (TrSialr) and of 70 kDa in the cell lysates of T. rangeli (TrSials) and T.

Trypanosoma rangeli: Epimastigote Immunogenicity and Cross-Reaction with Trypanosoma cruzi

The Journal of Parasitology, 1996
Trypanosoma rangeli epimastigote components, able to elicit an immune response, were defined and compared with those found in Trypanosoma cruzi epimastigotes. Using polyclonal antibodies against these parasites and immunoblotting analysis, an antigenic similarity index of 0.48 was found when anti-T.

Frequency and Distribution of Trypanosoma Cruzi and Trypanosoma Rangeli in the Republic of Panamá

The American Journal of Tropical Medicine and Hygiene, 1971
Abstract To provide information on the frequency and distribution of human trypanosomiasis in the Republic of Panama, we carried out a survey of the rural population in the nine provinces and the San Blas Territory. After direct examination of blood and hemoculture procedures, we examined 12,975 blood samples, corresponding to 10,570 persons, for ...

TRYPANOSOMA SAIMIRII RODHAIN, A JUNIOR SYNONYM OF TRYPANOSOMA RANGELI TEJERA

Journal of Parasitology, 2005
In the present study, we used sodium dodecyl sulfate-polyacrylamide gel electrophoresis to compare polypeptides of trypanosomes isolated by hemoculture of squirrel monkeys displaying Trypanosoma saimirii blood trypomastigotes, with other trypanosomes that infect primates to evaluate the validity of T. saimirii.

Use of Micro-Elisa for Quantitating Antibody to Trypanosoma Cruzi and Trypanosoma Rangeli

The American Journal of Tropical Medicine and Hygiene, 1979
Of 229 residents of a Panamanian village where both Trypanosoma cruzi and Trypanosoma rangeli are endemic, 52% had antibody to one or both species by the enzyme-linked immunosorbent assay (ELISA), 26% were positive by complement fixation, 17% were positive by direct agglutination, and 32% were positive on the basis of clinical impression.
