T. cruzi antigen and DNA in urine and relationship with systemic detection of the parasite.

aPCR from blood samples are the results obtained using primers TcZ1/TcZ2.bPCR from cardiac tissue are the results obtained using primers TcZ1/TcZ2.cA sample was considered to be antigenuria positive when we detected any of the bands of 75 kDa, 80 kDa, 120 kDa and 150 kDa.dTrans-renal DNA are the results obtained using the primers TcZ1/TcZ2.eNumber of animals in acute phase = 40.fNumber of animals in chronic phase = 20.
