Trypanosoma cruzi : sensitivity of the polymerase chain reaction for detecting the parasite in the blood of mice infected with different clonal genotypes.

The polymerase chain reaction showed high sensitivity for detecting Trypanosoma cruzi in the blood of mice, independent of clonal genotype (19, 20?T. cruzi I; 32, 39?T. cruzi II) or phase of the infection (acute or chronic)
