“…On the other hand, although Trypanosoma rangeli infection in humans is harmless, this parasite is a serious concern for the epidemiology and diagnosis of Chagas disease due to its morphological similarity and immunological cross-reactivity with T. cruzi 14 . Moreover, these trypanosomes are sympatric and share triatomine insects as well as vertebrate hosts, allowing the occurrence of mixed infections 7 .…”

“…Moreover, these trypanosomes are sympatric and share triatomine insects as well as vertebrate hosts, allowing the occurrence of mixed infections 7 . Colombia is one of the countries in which T. cruzi shares vectors and reservoirs with T. rangeli 7,13,14 . Recently, two important epidemiological groups of T. rangeli have been described: KP1(-) strains, associated with the adaptive line of Rhodnius, represented by R. colombiensis, R. pallescens, and R. ecuadoriensis, and KP1(+) strains, associated with R. prolixus [30][31][32] .…”

SUMMARYTrypanosoma rangeli is non pathogenic for humans but of important medical and epidemiological interest because it shares vertebrate hosts, insect vectors, reservoirs and geographic areas with T. cruzi, the etiological agent of Chagas disease. Therefore, in this work, we set up two PCR reactions, TcH2AF/R and TrFR2, to distinguish T. cruzi from T. rangeli in mixed infections of vectors based on amplification of the histone H2A/SIRE and the small nucleolar RNA Cl1 genes, respectively. Both PCRs were able to appropriately detect all T. cruzi or T. rangeli experimentally infected-triatomines, as well as the S35/S36 PCR which amplifies the variable region of minicircle kDNA of T. cruzi. In mixed infections, whereas T. cruzi DNA was amplified in 100% of samples with TcH2AF/R and S35/S36 PCRs, T. rangeli was detected in 71% with TrF/R2 and in 6% with S35/S36. In a group of Rhodnius colombiensis collected from Coyaima (Colombia), T. cruzi was identified in 100% with both PCRs and T. rangeli in 14% with TrF/R2 and 10% with S35/S36 PCR. These results show that TcH2AF/R and TrF/R2 PCRs which are capable of recognizing all T. cruzi and T. rangeli strains and lineages could be useful for diagnosis as well as for epidemiological field studies of T. cruzi and T. rangeli vector infections.

“…Trypanosoma rangeli has been reported in Colombia, Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Guyana, Fr Guyana, Uruguay, Paraguay, Peru, Chile, Venezuela, Trinity, Argentina, Ecuador, Bolivia and Brazil 2,3 . In Brazil, it was found in wild animals and triatomines in the south (Santa Catarina), southeast (Minas Gerais), northeast (Ceará, Alagoas and Bahia), central west (Federal District, Goiás, Mato Grosso and Mato Grosso do Sul) and north (Amazonas, Pará, Rondônia, Acre and Tocantins) regions 2,4,5 .…”

Introduction: This study reports for the fi rst time the infection of Rhodnius montenegrensis by Trypanosoma rangeli. Methods: The triatomines were manually collected in Attalea speciosa in the municipality of Buritis, Rondônia. The identifi cation of the trypanosomatid species was confi rmed by multiplex PCR. Results: All of the collected triatomines were R. montenegrensis. The analysis confi rmed that all of the adults were infected with the epimastigote form of T. rangeli. Conclusions: This report of a new vector of T. rangeli raises a warning for the State of Rondônia because the simultaneous presence of T. rangeli with T. cruzi in the same geographic region enables the occurrence of mixed infections in hosts and vectors, which complicates the differential diagnosis.
