      Background: The Trypanosoma cruzi satellite DNA (satDNA) OligoC-TesT is a standardised PCR format for diagnosis of Chagas disease. The sensitivity of the test is lower for discrete typing unit (DTU) TcI than for TcII-VI ...
    • Campos Soto, Ricardo; Díaz Campusano, Gabriel; Quiroga, Nicol; Muñoz San Martín, Catalina; Rives Blanchard, Ninette; Torres Pérez, Fernando (Peerj Inc, 2020)
      Trypanosoma cruzi, the cause agent of Chagas disease, is transmitted mainly by blood-feeding insects of the subfamily Triatominae. The T. cruzi life cycle alternates between triatomines and mammalian hosts, excluding birds ...
