Parasitaemia by qPCR. Quantitative PCR amplification of the T. cruzi satellite DNA from the blood of TcN-infected untreated mice and treated with BNZ-MP or BNZ at 50 mg kg⁻¹ day⁻¹ (RL 50, RS 50 or BNZ 50, respectively). Each symbol represents the parasite equivalents mL⁻¹ (Eq mL⁻¹) at 92 d.p.i. measured by qPCR in each mouse as described in the Materials and methods section. The dotted line represents the limit of detection of the technique.
