The weight of PbA-C57BL/6 mice started to decrease significantly on day 6 post infection and was the lowest on day 8 both in groups A (− 0.08 ± 0.05% decrease) and B (− 0.08 ± 0.02% decrease), when there was a highly significant difference between the PbA-infected group and the uninfected control group ( p = 9.27 × 10 −11 , Student’s t test) (Fig. 2 a).
