Untangling the transmission dynamics of primary and secondary vectors of Trypanosoma cruzi in Colombia : Parasite infection, feeding sources and discrete typing units
(2016)
Background: Trypanosoma cruzi is the causative agent of Chagas disease. Due to its genetic diversity has been classified into six Discrete Typing Units (DTUs) in association with transmission cycles. In Colombia, natural ...
Simple methodology to directly genotype Trypanosoma cruzi discrete typing units in single and mixed infections from human blood samples
(Elsevier Science, 2016-09)
Different DNA markers to genotype Trypanosoma cruzi are now available. However, due to the low quantity of parasites present in biological samples, DNA markers with high copy number like kinetoplast minicircles are needed. ...
Infecção por Trypanosoma spp. em mamíferos cativos da Fundação Parque Zoológico de São Paulo, e em triatomíneos e pequenos mamíferos silvestres das áreas de mata do entorno
(2019)
Trypanosoma cruzi é um protozoário flagelado da família Trypanosomatidae, cujo ciclo de transmissão é primariamente enzoótico. É um parasito antigo de mamíferos selvagens. Infecções causadas por Trypanosoma cruzi em animais ...
Are all bony fishes oxygen regulators? Evidence for oxygen regulation in a putative oxygen conformer, the swamp eel Synbranchus marmoratus
(2019-01-01)
This study investigated the oxygen consumption of the putative oxygen conformer marbled swamp eel Synbranchus marmoratus during progressive hypoxia. Earlier studies have not reached an agreement on whether S. marmoratus ...
Geographic variation of Trypanosoma cruzi Discrete Typing Units from the main vector Triatoma infestans at different scales
(Elsevier, 2014-08-01)
tWe assessed the diversity and distribution of Trypanosoma cruzi discrete typing units (DTU) in Triatomainfestans populations and its association with local vector-borne transmission levels at various geographicscales. At ...
Diagnóstico parasitológico e molecular da doença de Chagas humana e tipagem do Trypanosoma cruzi recém-isolado de pacientes portadores de diferentes formas clínicas
(Universidade Federal de Minas GeraisUFMG, 2013-05-17)
This study evaluated two diagnostic methods for Chagas disease, such as blood culture and polymerase chain reaction (PCR) as well as genetic profile of Trypanosoma cruzi populations freshly isolated from 91 untreated chronic ...
Lectinoma de Trypanosoma cruzi: nova ferramenta para caracterização das Discrete Typing Units (DTUs)
(Universidade Estadual Paulista (Unesp), 2017)
O Trypanosoma cruzi causa uma infecção conhecida como doença de chagas. Ele possui seis subdivisões genéticas, as Discrete Typing Units (DTUs Tc I a VI), que possuem características distintas como sua distribuição geográfica ...
Expressão gênica dos alelos da proteína P21 na infectividade de cepas pertencentes a diferentes linhagens filogenéticas de Trypanossoma cruzi
(Universidade Federal de UberlândiaBRPrograma de Pós-graduação em Imunologia e Parasitologia AplicadasCiências BiológicasUFU, 2016)
Guide RNA Repertoires in the Main Lineages of Trypanosoma cruzi: High Diversity and Variable Redundancy Among Strains
(Frontiers Media, 2021-05-31)
Trypanosoma cruzi, as other kinetoplastids, has a complex mechanism of editing of mitochondrial mRNAs that requires guide RNAs (gRNAs) coded in DNA minicircles in the kinetoplast. There are many variations on this mechanism ...
