| Abstract | dc.description.abstract | To identify Trypanosoma cruzi clones from chronically infected individuals, they were transferred to triatomines by the xenodiagnosis test (XD) with Triatoma infestans. Polymerase chain reaction (PCR) and hybridization assays were performed to detect minicircle DNA in human blood samples and triatomine feces, using probes to determine the T. cruzi clones present. T. cruzi clone 19 (TcI) resulted the most prevalent in humans, with a frequency of 0.70 compared with a frequency of 0.53 in triatomines. T. cruzi clone 39 (TcIId) was the most prevalent in T. infestans, with a frequency of 0.65 compared with 0.33 in humans. The T. cruzi clone 43 (TcIIe) was not detected in blood samples; nevertheless, it was present at a rate of 0.17 in T infestans feces. In conclusion, the T. cruzi clones are associated to each host, suggesting that selective amplification of clones occurs in human and triatomines. | en |
