“…It should be noted that this level of parasitaemia corresponds to an intraperitoneal inoculum of 5 × 10 5 T. cruzi Arequipa BTs; inocula of (a) 5.0 × 10 3 BTs and (b) 5.0 × 10 4 BTs were also tested, but (a) no parasitaemia was detected (by 1/100 diluted blood microscopic counting) and, (b) parasitaemia with a mean peak lower than 0.2 × 10 parasites⋅mL -1 was shown (but infection did not occur in all mice in this group). Our experience with other strains (Olmo et al, 2015;García--Huertas et al, 2018) and a review of the literature (Rodrigues et al, 2022) suggest that the parasitaemia curve is inoculum-and strain-dependent.…”
